Beavers

Mon, 24 Nov 2025 01:07:00 +0000

Beavers are castorimorph rodents, a suborder of rodents who live in North America and Europe. There are two species of beaver, the European or Eurasian beaver (Castor fiber) and the North American beaver (Castor canadensis). Beavers are the second largest rodent in the world after the capybara.

Beavers have webbed hind-feet, and broad, scaly tails. Beavers do not have good eyesight, but they posses good senses of smell, hearing, and touch. Their teeth grow continuously throughout their lives so as not to be worn down by chewing wood. Their powerful front teeth are used to cut trees and plants used by beavers for food and for constructing their homes. While slow on land, beavers are excellent swimmers and are able to stay under water for around 15 minutes.

Beavers are herbivores. They prefer the wood of birch, maple, cottonwood, willow, quaking aspen, alder and cherry trees. They also eat water lilies, sedges and pondweed.

Beavers are well known for building dams on rivers and streams, and for building "lodges" in the ponds created by their dams. They also construct canals used to float their building materials. Their incredible construction abilities makes beavers a keystone species as they create wetlands that are inhabited by many other species. No other animal, with the exception of humans, shapes their landscape as much as beavers. The ponds and the wetlands they create help to remove sediments and pollutants from waterways.

If a beaver's chosen home has no existing ponds, they must construct a dam along a river to create a pond before building their lodges. Sometimes they create a series of dams. The dams also provide protection against predators, such as bears, coyotes and wolves, and create easy access to food sources during the winter months.

To construct a dam, beavers erect vertical poles which are then filled with a crisscross of horizontal branches. The gaps between the branches are stuffed with weeds and mud. They always work at night. Beavers carry their building supplies with their fore-paws and their teeth.

Beaver lodges are constructed similarly to their dams. Lodges have underwater entrances, making it almost impossible for other types of animals to enter. Two den areas within the lodge allow a space for drying off, and another space designated as a living area.

Lodges house up to four adult beavers and up to eight children. Beavers spend the winter in their lodges with a winter stock of wood for eating. Throughout winter, they eat the underbark of sticks and logs they keep stored in their ponds. The top of the pile accumulates snow in the winter, insulating the water and providing an area where they can breathe when outside their lodge. When the ice breaks up in the spring, they leave their lodges to roam until fall.

Eurasian beavers don’t always build lodges—sometimes they dig burrows in stream banks. The entrance, however, is also underwater.

Beavers are known for their unique alarm signal. Frightened and startled beavers rapidly dive while slapping the water with their tails, making a loud sound that can be heard both above and below water. The warning signal alerts other nearby beavers to dive to safety.

Beaver families consist of a monogamous adult male and female couple and their kits and yearlings. While they mate for life; if their spouse dies they will partner with another beaver. Beaver families have up to ten members, in addition to the pair. The mother and father both take part in raising the children. They also both mark and defend their territory, and together they build and repair their dams and lodges.

Baby beavers spend their first month inside the lodge, being taken care of mostly by their mother while their father maintains the territory. They spend most of their time playing. As yearlings they learn to help their parents repair dams and lodges and collect food caches in the fall. Older offspring often continue to live with their families. They continue to help keep up repairs and build food caches, and also help with grooming, feeding, and guarding younger beavers. Older siblings will also take over the responsibility of parenting if the original parents die or are somehow separated from them.

When beavers do leave their childhood home, they usually do not move far away. They recognize their family members through smells created by anal gland secretions, creating more tolerant behavior among neighboring beavers.

Beavers continue to grow throughout their lives, with adults growing to over 55 lb. Females are as big as or larger than males. In the wild, beavers live up to 24 years.

THREATS TO BEAVERS

There were once over 60 million North American beaver, but as a result of hunting for its fur, its glands for medicine and because the beavers tree-felling and dams affect other land uses, the population has declined to around 12 million.

The principal threats to beaver populations are habitat destruction and degradation. Human population growth and increasing demands on water resources lead to water storage, diversion, and channelization projects that affect rivers, lakes, and wetlands. Water uses can cause short and long-term effects on beaver habitat by changing seasonal flow regimes and stream morphology, and by causing loss or degradation of riparian vegetation.

Intense grazing by wild and domestic ungulates in a riparian zone is also a primary cause of beaver habitat degradation. Although commercial trapping is no longer a threat to the species, depredation trapping to mitigate beaver damage, and illegal shooting and trapping are localized threats.

Koalas

Sun, 23 Nov 2025 01:07:00 +0000

ADOPT A KOALA

Koalas have soft, wool-like fur that is gray above and white below. Their fur is mostly white on the underside below the neck, and their ears have long white hairs on the tips. The koala resembles a bear, but is actually a marsupial, a special kind of mammal which carries its young in a pouch. They are rather small, round animals, weigh about 30 pounds and on average grow to be 2 feet tall.

Koalas can live as long as 17 years, although high mortality rates (due to car fatalities and dogs) for males lower their life expectancy to 2 to 10 years. The koala's historic range stretches across Australia. Today they can be found only in Queensland, New South Wales, Victoria, and South Australia. There are fewer than 100,000 koalas left in the wild.

Koalas prefer to live in eucalyptus forests, coastal islands, and low woodlands. They consume eucalyptus leaves and bark from 12 different eucalyptus tree species. They also consume mistletoe and box leaves.

Nocturnal mammals, koalas sleep for up to 20 hours a day. They are arboreal, which means that they live in trees. They do not live in big groups but rather prefer to be alone. Females are solitary and occupy distinct home ranges that they rarely leave. In the more fertile areas, these ranges overlap; in areas where suitable food trees are scarce they tend to be larger and more exclusive. Males are not territorial, but do not tolerate one another, particularly not during the breeding season. Dominant individuals attack subordinate ones, and most adult males carry scars on their face, ears and forearms as a result.

The koala does not make nests, but sleeps in a tree fork or on a branch. It climbs using its powerful claws for gripping, usually moving quite slowly but can climb rapidly when needed.

The koala will leap confidently from one tree to another if they are reasonably close together. Its climbing is aided by a pair of thumbs on each paw, and it is the only other animal aside from primates to possess fingerprints. Longer distances are traversed on the ground in a slow but effective waddle. If threatened, the koala breaks into a surprisingly athletic gallop, heading for the nearest tree and bounding up it to a safe height. There the koala waits for the intruder to go away. The koala is also rather adept at swimming.

Koalas breed once a year. Gestation lasts 35 days, after which one koala is born. A baby koala is referred to as a joey and is hairless, blind and earless. At birth the joey, only the size of a jelly bean, crawls into the downward facing pouch on the mother's belly (which is closed by a drawstring like muscle that the mother can tighten at will) and attaches itself to one of the two teats. Young remain hidden in the pouch for about six months, only feeding on milk. During this time they grow ears, eyes and fur. The joey then begins to explore outside of the pouch. At about 30 weeks it has begun to eat the semi liquid form of the mother’s excrement called "pap". The baby koala will remain with the mother for another six months or so, riding on her back, and feeding on both milk and gum leaves until weaning is complete at about 12 months of age. Young females disperse to nearby areas at that time; young males often stay in the mother's home range until they are two or three years old.

THREATS TO KOALAS

Once numbering in the millions, koalas suffered major declines in population during the 1920s when they were hunted for their fur. The koala was hunted almost to extinction. Today, habitat destruction, traffic deaths, and attacks by dogs kill an estimated 4,000 koalas yearly. In recent years, some colonies have been hard hit by disease, especially chlamydia. The koala requires large areas of healthy, connected forest and will travel long distances along tree corridors in search of new territory and mates. The ever increasing human population of the coastal parts of the continent continues to cut these corridors by agricultural and residential development, forestry and road building...marooning koala colonies in decreasing areas of bush. Although the species covers a massive area, only 'pieces' of Koala habitat remain. These pieces need to be managed, protected and restored in a coordinated way. Presently, many are being lost to weeds, cleared for agriculture, or carved up by developers.

In contrast to the situation on much of the mainland, where populations are declining, the koalas of many island and isolated populations have flourished. In the absence of predators and competition, combined with an inability to migrate to new areas, koala populations can become unsustainable. Although culling has been suggested as a means to reduce koala numbers, this has met with fierce opposition both domestically and internationally, and the species remains protected. The popularity of the koala has made the possibility of a cull politically improbable, with any negative perception likely to impact on tourism and a government's electability. In place of a cull, sterilization and translocation programs have had only limited success in reducing numbers thus far, and remain expensive. There is evidence that koalas relocated to the mainland have difficulty establishing themselves in the different circumstances. A mooted alternative to the complex sterilization method, wherein the animal must first be captured, are hormonal implants that can be injected via darts.

Koalas displayed to the public for human entertainment are disturbed constantly by human visitors, putting them in an alert state which interrupts their normal activity resulting in chronic stress. This is even more hazardous for koalas than for other species, since koalas have an extremely low energy diet of eucalyptus leaves and must minimize energy by sleeping 18 to 20 hours a day. Even in captivity, koalas need to sleep most of the day. Some “wildlife parks” and zoos even allow hands-on experiences with koalas, increasing their level of stress.

Porcupines

Sat, 22 Nov 2025 01:08:00 +0000

ADOPT A PORCUPINE

Porcupines are rodents with a coat of sharp spines, or quills, that protect them against predators. The term covers two families of animals, the Old World porcupines and New World porcupines. Both families belong to the Hystricognathi branch of the vast order Rodentia, both display similar coats of quills, but they still are quite different and are not closely related.

Porcupines occupy a short range of habitats in tropical and temperate parts of Asia, Southern Europe, Africa, and North and South America. Porcupines live in forests, deserts, rocky outcrops and hillsides. Some New World porcupines live in trees, but Old World porcupines stay on the rocks. Porcupines can be found on rocky areas up to 12,100 feet high.

Porcupines are the third largest of the rodents, behind the capybara and the beaver. Most porcupines are about 25 to 36 inches long, with an 8 to 10 inch long tail. Weighing 12 to 35 lb, they are rounded, large and slow. Porcupines come in various shades of brown, gray, and the unusual white. Porcupines' spiny protection resembles that of the unrelated hedgehogs and Australian spiny anteaters.

Quills come in varying lengths and colors, depending on the animal's age and species. Porcupines' quills, or spines, take on various forms, but all are modified hairs coated with thick plates of keratin, and embedded in the skin musculature. Old World porcupines have quills embedded in clusters, whereas in New World porcupines, single quills are interspersed with bristles, underfur and hair. Quills are released by contact with them or may drop out when the porcupine shakes its body. New quills grow to replace lost ones.

Porcupines have a relatively high longevity and had held the record for being the longest-living rodent, until it was recently broken by the naked mole-rat.

The New World porcupines are indigenous to North America and northern South America. They live in wooded areas and can climb on trees, where some species spend their entire lives. They are less strictly nocturnal than their Old World relatives, and generally smaller. In taxonomic terms they form the family of the Erethizontidae.

The two subfamilies of New World porcupines are mostly smaller than Old World porcupines, have their quills attached singly rather than grouped in clusters, and are excellent climbers. The New World porcupines are more closely related to several other families of rodent than they are to the Old World porcupines.

New World porcupines are stout animals, with blunt, rounded heads, fleshy, mobile snouts, and coats of thick, cylindrical or flattened spines ("quills"). The spines are mixed with long, soft hairs. They vary in size from the relatively small prehensile-tailed porcupines, which are around 12 inches long, and weigh about 32 oz, to the much larger North American porcupine, which has a body length of 34 inches, and weighs up to 40 lb.

They are distinguished from the Old World porcupines in that they have rooted molars, complete collar bones, entire upper lips, no trace of first front toes, and four teats. Their long and powerful prehensile tails help them balance when they are in the tree tops. Their diets consist mainly of bark, leaves, and conifer needles, but can also include roots, stems, berries, fruits, seeds, nuts, grasses, and flowers. Some species also eat insects and small reptiles. Solitary offspring (or, rarely, twins) are born after a gestation period of up to 210 days, depending on the species. The young are born fully developed, with open eyes, and are able to climb trees within a few days of birth.

The Old World porcupines live in southern Europe, Asia, and most of Africa. They are large, terrestrial, and strictly nocturnal. In taxonomic terms they form the family of the Hystricidae. The eleven Old World porcupines tend to be fairly big, and have spikes that are grouped in clusters.

Old World porcupines are stout, heavily built animals, with blunt, rounded heads, fleshy, mobile snouts, and coats of thick cylindrical or flattened spines, which form the whole covering of their bodies and are not intermingled with ordinary hairs. The habits of most species are strictly terrestrial. They vary in size from the relatively small long–tailed porcupine with body lengths of 11 to 18.9 inches, and a weight of 3.3 to 5.1 lb, to the much larger crested porcupines, which are 24 to 33 inches long, discounting the tail, and weigh from 29 to 60 lb.

The various species are typically herbivorous, eating fruit, roots, and bulbs. Some species also gnaw on dry bones, perhaps as a source of calcium. Like other rodents, they have powerful gnawing incisors, and no canine teeth. One or two (or, rarely, three) young are born after a gestation period between 90 and 112 days, depending on the species. Females typically give birth only once a year, in a grass-lined underground chamber within a burrow system. The young are born more or less fully developed, and the spines, which are initially soft, harden within a few hours of birth. Although they begin to take solid food within two weeks, they are not fully weaned until 13 to 19 weeks after birth. The young remain with the colony until they reach sexual maturity at around two years of age, and share the burrow system with their parents and siblings from other litters. Males, in particular, help defend the colony from intruders, although both sexes are aggressive towards unrelated porcupines.

Old World porcupines are also characterized by imperfectly rooted cheek-teeth, imperfect collar-bones, cleft upper lips, rudimentary first front-toes, smooth soles, six teats arranged on the side of the body, and many cranial characters.

THREATS TO PORCUPINES

Porcupines are only occasionally eaten in western culture, but are very popular in Southeast Asia, particularly Vietnam, where the prominent use of them as a food source has contributed to significant declines in their populations. Kenya porcupines are eaten as a delicacy. Overhunting has been cited as the porcupine's greatest threat. They are also commercially farmed.

Porcupine quills have long been harvested for clothing, musical instruments, containers and accessories. When porcupine populations are near cultivated areas, they can become viewed as “agricultural pests”. They are smoked out of their burrows and hunted with spears, nets, or dogs. These practices have eliminated them from densely settled areas.

Jaguars

Fri, 21 Nov 2025 01:08:00 +0000

ADOPT A JAGUAR

It’s no surprise that pre-Columbian South Americans once revered the jaguar as a potent symbol of power and strength – these enormous felines are some of the most impressive and beautiful members of all the large cat species, and the only Panthera species from the Felidae family that’s native to the Americas. These powerful predators are at the top of their food chain, and they have a current range that extends from the southwestern United States (though extremely rare in occurrence there) down to Mexico, Central America, and northern Argentina. While they do prefer rainforest habitat, they can also thrive across a range of forested habitats as well as more open living environments, especially those near water – jaguars happen to be talented swimmers.

Interestingly, research into the DNA of the jaguar shows that it shares a common ancestor with lions and tigers, but the jaguar is the most similar in appearance to the spotted leopard. Their body is compact, muscular and stocky, with shorter legs than other big cat species, allowing them to skillfully climb, crawl or leap after their prey. Their tawny coats blend in exceptionally well with the dappled lights of their forested habitats, usually ranging from tawny yellow to red-brown in color, with black rosettes or spots over the body, neck and tail. Their underside is typically white, however, similar to other large cats.

In some individuals, a color morph coat variation occurs, with the coat appearing almost black, but with spots still highly visible, while the completely melanistic coat variation (which is entirely black with extremely faint discernible spots) happens far more rarely. These jaguars are referred to as black panthers, though they’re still classified as the same species.

A jaguar’s blocky, muscular head also means that it has an extremely forceful bite, allowing it to crush the heavy bones of its prey and even pierce tough turtle shells. These big cats can vary in weight and height, depending on habitat (more southern dwelling jaguars tend to be bigger), ranging anywhere from 125-210 lb and 25 to 30 inches at the shoulder, with males typically reaching sizes 10 to 20 percent larger than females.

As the largest carnivores in Central and South America, jaguars are devastatingly effective hunters with a diet that includes over 80 species. Hunting mainly in the early evening and early morning, they prefer prey that’s as big or often even larger than they are, since they need to eat several pounds of food at a time to meet their energy requirements. They’ll even gorge on meat between hungry periods, and some jaguars have been seen to eat up to 50lb or more at one sitting. A jaguar’s diverse buffet includes caimans, deer, tapirs, dogs, anacondas, fish, sloth, monkeys, frogs, mice, and armadillos. Even sea turtles (which can reach an average weight of around 350lb) are on the menu.

Because the jaguar has a physiology that’s more effective for simply overpowering its prey, it tends to stalk and ambush rather than sprint to catch each meal, quickly immobilizing it by biting the animal’s skull or grasping their head between paws and mouth to dislocate their neck. Jaguars will even hunt their prey into the water, since they can easily drag large prey onto the bank and up a tree, or to a more secluded spot to eat. Although they’ll return to larger kills multiple times, they’ll usually consume the more nutrient-dense heart and lungs of their prey in the first meal.

Like many other large cat species, these fascinating hunters are solitary dwellers, with the exception of mothers and their cubs. Adults tend to secure sizable territories for themselves, marking them with urine, feces and scratch marks, but generally avoiding other jaguars outside of mating season. They will communicate to one another through various vocal antics. Roaring is used to warn competitors away, and grunts and mews are used during courtship and counter-calling. Any aggression or conflict that happens is usually between males when they intrude on each others territory.

While jaguars have no specific mating season, they don’t reach sexual maturity until at least two years of age (males take three or four years). Both male and female will extend their territories during the time when the female is in season, although after mating they separate and the female raises the cubs entirely on her own to prevent the male from killing them (similar to tiger behavior). Cubs, born 3 to 4 months after mating, are usually born small, weak and blind in litters of two to four, weaning after three months but staying almost exclusively in their birth den until around six months of age. At this point, they start travelling with their mother on hunts, and eventually leave her side at one to two years of age to eke out their own territories. In the wild, the average jaguar lifespan is thought to be around 12 to 15 years, although some can live well over 20 years of age in captivity.

THREATS TO JAGUARS

Because of its role as an apex predator (at the top of its food chain), the jaguar has no natural predators in the wild, though it plays an important role in controlling the population levels of other, smaller species. Threats from human activity are another story, however; the continued loss and fragmentation of jaguar habitat through deforestation is a major risk for most jaguar populations. Hunting is also another issue contributing to the decline in jaguar numbers; not only by poachers, but also by ranchers who shoot jaguars that prey on their livestock. Jaguars are currently listed as Near Threatened by the IUCN, is illegal to hunt in many countries, and trade in jaguars or their parts is prohibited internationally by CITES.

Jaguars are rarely used today in circus acts, but are often displayed for entertainment at zoos. Jaguars kept captive in zoos are known for pacing due to the stress and frustration of their inability to carry out their natural routines and behaviors. Their stressful pacing increases as the number of visitors and noise level increases. Zoo jaguars are deprived of their natural environments and social structures for profit and human amusement.

Amphibians

Fri, 21 Nov 2025 01:08:00 +0000

ADOPT AN AMPHIBIAN

Amphibians are cold blooded, breathe air through their skin and do not have hair or scales. Amphibians go through a metamorphosis; starting from an egg, morphing into larvae that is typically aquatic, breathing by gills, and growing into semi-terrestrial adults that breathe by lungs and through moist skin.

REPTILE OR AMPHIBIAN?

Amphibious means ‘belonging to both land and water’ - but not all amphibious creatures are amphibians. Marine iguanas, sea snakes, crocodiles and pond turtles are all amphibious but they are considered reptiles because they do not go through a metamorphosis. They also have scales; amphibians have no scales. While both amphibians and reptiles come from eggs, amphibian eggs need to stay moist or wet as they develop and are usually laid in water.

WHO’S INCLUDED?

Amphibians include frogs, toads, newts, salamanders and caecilians – who resemble earthworms or snakes and hide in the ground, making them the least familiar of amphibians.. Most amphibians eat small animals like insects. Amphibians are divided into 3 major groups; salamanders, frogs and toads.

Amphibian Extinction Crisis

Amphibians have the sad privilege of being endangered more than any other animal group. At least 30 percent of all amphibian species are now threatened to disappear. Toads, frogs, and salamanders are vanishing due to animal agriculture, habitat loss, air and water pollution, global warming, UV light exposure, disease, and the introduction of exotic species. Because this group of animals is overly sensitive to environmental change, they should be regarded as the canary in the global coal mine. Amphibians alert us to minor but definite changes in the ecosystem that could lead to the extinction of many more species, not excluding humans.

FASCINATING AMPHIBIAN FACTS

THE BIGGEST

The largest amphibian is the giant salamander at 4 feet 8 inches long. The giant salamander is also the heaviest, weighing in at a whopping 88 pounds.

THE SMALLEST

The smallest amphibian in the world is a frog from New Guinea, Paedophryne amauensis, at only 0.30 inches.

THE FASTEST

The fastest amphibian is an Andean salamander, which can travel at speeds of 15 mph.

THE LONGEST LIVED

The giant salamander lives the longest, over 50 years.

METAMORPHOSIS

Baby amphibians hatch from eggs in water, starting off as polliwogs or tadpoles with no limbs and breathing through gills like fish. Some amphibians care for their eggs and babies, while others abandon their eggs in water and offer no care. When amphibian eggs hatch, the babies do not look like their parents. They start off as a larva, then undergo metamorphosis to transform into an adult form. Some amphibians, like toads, the process of going from an egg to a toad may only takes a few weeks. For others, like bullfrogs, the process may take two years.

DEVOTED DADS

Giant South African bullfrogs are devoted fathers who have attacked lions and elephants while defending tadpoles. Some male frogs in the rainforest, who send messages by drumming with their feet, are the sole caretakers of their young. After the mother lays eggs, the father guards the nest and carries his children on his back.

Scorpions

Thu, 20 Nov 2025 01:08:00 +0000

ADOPT A SCORPION

Scorpions are predatory arthropod animals of the order Scorpiones within the class Arachnida. They have eight legs and are easily recognized by a pair of grasping pincers (claws) and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. They have adapted to a wide range of environmental conditions and can now be found on all continents except Antarctica. Scorpions did not occur naturally in Great Britain, New Zealand and some of the islands in Oceania, but now have been accidentally introduced in some of these places by human trade and commerce.

Scorpions are invertebrates but are not considered insects. Scorpions, along with ticks, mites, harvestmen and spiders, are called arachnida.

Scorpions number about 1,750 described species. Only about 25 of these species are known to have venom capable of killing a human being.

Scorpions prefer areas where the temperatures range from 68 to 99 °F, but may survive temperatures ranging from well below freezing to desert heat. They are nocturnal and fossorial (adapted to digging and life underground), finding shelter during the day in the relative cool of underground holes or undersides of rocks, and emerging at night to hunt and feed. Scorpions exhibit photophobic behavior (they prefer to stay out of the light), primarily to evade detection by predators such as birds, centipedes, lizards, mice, possums and rats.

Scorpions are opportunistic predators of small arthropods, although the larger kinds have been known to kill small lizards and mice. The large pincers are studded with highly sensitive tactile hairs, and the moment an insect touches these, they use their pincers to catch the prey. Depending on the toxicity of their venom and size of their claws, they will then either crush the prey or inject it with neurotoxic venom. This will kill or paralyze the prey so the scorpion can eat it. Scorpions have an unusual style of eating using chelicerae, small claw-like structures that protrude from the mouth. The chelicerae, which are very sharp, are used to pull small amounts of food off the prey. Scorpions can ingest food only in a liquid form; they have external digestion. Digestive juices from the gut are excreted onto the food to liquify it.

Scorpions can consume huge amounts of food at one sitting. They have a very efficient food storage organ and a very low metabolic rate combined with a relatively inactive lifestyle. This enables scorpions to survive long periods when deprived of food; some are able to survive 6 to 12 months of starvation. Scorpions excrete very little waste.

Most scorpions reproduce sexually, and most species have male and female individuals. However, some species reproduce through parthenogenesis, a process in which unfertilized eggs develop into living embryos.

Scorpions possess a complex courtship and mating ritual. Mating starts with the male and female locating and identifying each other using a mixture of pheromones and vibrational communication. Once they have satisfied the other that they are of opposite sex and of the correct species, mating can commence. The courtship starts with the male grasping the female; the pair then perform a dance called the "promenade à deux". In this dance, the male leads the female around searching for a suitable place to deposit his sperm capsule. When the male has identified a suitable location, he deposits the capsule and then guides the female over it. This allows the capsule to enter her, which triggers release of the sperm, thus fertilizing the female. The mating process can take from 1 to over 25 hours. Once the mating is complete, the male and female will separate. The male will generally retreat.

Baby scorpions are carried about on their mother's back until they have undergone at least one moult. Before the first moult, scorplings cannot survive naturally without the mother, since they depend on her for protection and to regulate their moisture levels. Mothering can continue for an extended period of time. The size of the litter depends on the species and environmental factors, and can range from two to over a hundred scorplings. The average litter, however, consists of around 8 scorplings.

Baby scorpions generally resemble their parents. Growth is accomplished by periodic shedding of the exoskeleton. Scorpions typically require between five and seven moults to reach maturity. Moulting commences with a split in the old exoskeleton. The scorpion then emerges from this split. When it emerges, the scorpion's new exoskeleton is soft, making the scorpion highly vulnerable to attack. The scorpion must constantly stretch while the new exoskeleton hardens to ensure that it can move when the hardening is complete.

All known scorpion species possess venom and use it primarily to kill or paralyze their prey so that it can be eaten. In general, it is fast-acting, allowing for effective prey capture. However, as a general rule they will kill their prey with brute force if they can, as opposed to using venom. Venom is also used as a defense against predators.

THREATS TO SCORPIONS

Like most animals, the primary threat to scorpions is the destruction of their habitat. Human development has taken an alarming toll on the environment. Impact from land use practices such as agricultural conversion, deforestation, and urban sprawl continue to degrade and fragment remaining pockets of habitat and accelerate biodiversity loss. Pesticides and other forms of pollution are also of serious concern, as well as genetically modified organisms (GMOs).

Scorpions are also threatened by the pet trade. Captivity is cruel for wild animals. Animals are captured from their native habitat and transported to various countries to be sold as “pets”. Backyard breeders also supply exotic animals. The sellers of these animals often disregard the dangers, difficulties, physical and physiological needs of the animals they peddle. The suffering of the animals in the hands of unqualified and hapless buyers appears to be of no concern in the lucrative exotic pet trade.

Corals

Wed, 19 Nov 2025 01:09:00 +0000

ADOPT A CORAL

Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.

Corals are sessile, which means that they permanently attach themselves to the ocean floor, essentially "taking root" like most plants do. We certainly cannot recognize them by their faces or other distinct body parts, as we can most other animals. So what exactly are corals? Corals actually comprise an ancient and unique partnership, called symbiosis, that benefits both animal and plant life in the ocean. Corals are animals, though, because they do not make their own food, as plants do. Corals have tiny, tentacle-like arms that they use to capture their food from the water and sweep into their inscrutable mouths.

Most structures that we call "coral" are, in fact, made up of hundreds to thousands of tiny coral creatures called polyps. Each soft-bodied polyp - most no thicker than a nickel - secretes a hard outer skeleton of limestone (calcium carbonate) that attaches either to rock or the dead skeletons of other polyps.

In the case of stony or hard corals, these polyp conglomerates grow, die, and endlessly repeat the cycle over time...slowly laying the limestone foundation for coral reefs and giving shape to the familiar corals that reside there. Because of this cycle of growth, death, and regeneration among individual polyps, many coral colonies can live for a very long time.

Most corals contain algae called zooxanthellae, which are plant-like organisms. Residing within the coral's tissues, the microscopic algae are well protected and make use of the coral's metabolic waste products for photosynthesis, the process by which plants make their own food. The corals benefit, in turn, as the algae produce oxygen, remove wastes, and supply the organic products of photosynthesis that corals need to grow, thrive, and build up the reef. More than merely a clever collaboration that has endured between some of the tiniest ocean animals and plants for some 25 million years, this mutual exchange is the reason why coral reefs are the largest structures of biological origin on earth, and rival old-growth forests in the longevity of their ecological communities.

Corals are a vital part of the marine world. There are around 70,000 different species of coral throughout the oceans of the world. They are most numerous in warm and tropical climates in the southern hemisphere.

Corals are divided into two subspecies based on how many tentacles they have. Corals with eight tentacles are known as Alcyonaria, which includes sea fans, soft coral and sea pens. Corals with more than eight tentacles are known as Zoantharia, which includes the coral species found in coral reefs.

Although some corals can catch small fish and plankton, using stinging cells on their tentacles, most corals obtain the majority of their energy and nutrients from algae that live within the coral's tissue. Corals require sunlight and grow in clear, shallow water, typically at depths shallower than 200 feet. Some species have adapted to living in deeper levels of the oceans.

Corals live from 3 months to 30 years, depending on the species. Coral species that make up the extensive coral reefs usually live much longer than species like the softer corals, which live on their own.

Coral reefs support more species than any other marine environment. Reefs rival rainforests in the amount of biodiversity they support. Thousands of creatures rely on coral reefs for their survival. They provide hiding places for marine animals to evade predators, and serve as a meeting and breeding ground.

Hidden beneath the ocean waters, reefs are also some of the oldest ecosystems on the planet, reflecting thousands of years of history. Although individual coral polyps are tiny, they create the largest living structures on earth - some reefs are visible from space.

THREATS TO CORAL

Coral reefs are under stress around the world. In particular, coral mining, agricultural and urban runoff, pollution (organic and inorganic), overfishing, blast fishing, disease, and the digging of canals and access into islands and bays are localized threats to coral ecosystems. Broader threats are sea temperature rise, sea level rise and pH changes from ocean acidification.

General estimates show approximately 10% of the world's coral reefs are dead. About 60% of the world's reefs are at risk due to human-related activities. The threat to reef health is particularly strong in Southeast Asia, where 80% of reefs are endangered. Over 50% of the world's coral reefs may be destroyed by 2030.

In the Caribbean and tropical Pacific, direct contact between common seaweeds and coral causes bleaching and death to the coral via transfer of lipid-soluble metabolites. Seaweed and algae proliferate given adequate nutrients and limited grazing by herbivores such as parrotfish.

Coral disease, tropical storms, tourism and recreation, vessel damage, marine debris and aquatic invasive species also threaten coral.

Many governments now prohibit removal of coral from reefs, and inform coastal residents about reef protection and ecology. While local action such as habitat restoration and herbivore protection can reduce local damage, the longer-term threats of acidification, temperature change and sea-level rise remain a challenge.

To eliminate destruction of corals in their indigenous regions, projects have been started to grow corals in non-tropical countries.

Fish

Tue, 18 Nov 2025 01:09:00 +0000

ADOPT A FISH

Fish are cold blooded, live in water and are covered in scales. They breathe through gills located on the sides of their heads. Their gills take oxygen out of the water around them so they can breathe. Their limbs, if they have any, are in the shape of fins and do not have digits. They exhibit greater species diversity than any other group of vertebrates, with over 32,000 known species.

Fish live in oceans and freshwater ecosystems. Well adapted to their water world, fish secrete a special type of mucus from their skin. The slime coating helps them move through water faster, protects them against parasites and diseases and covers wounds to prevent infection.

Most fish have color vision that is at least as good as a human's. Many fish also have chemoreceptors that are responsible for extraordinary senses of taste and smell. Sensitive receptors allow fish to detect gentle currents and vibrations, and to sense the motion of nearby fish and prey. Some fish have organs that detect electric currents. Some can even produce electric currents, which they use in navigation and social communication.

Fish orient themselves using landmarks and mental maps based on multiple landmarks or symbols. They possess spatial memory and visual discrimination.

Over 97% of all known fish are oviparous, that is, the eggs develop outside the mother's body. Newly hatched babies are called larvae and do not look like their parents until they go through metamorphosis.

Jaws allow fish to eat a wide variety of food, including plants and other organisms. Many are specialists, eating very limited diets. Others will eat almost anything. Cleaner wrasses eat parasites off of other fish, setting up cleaning stations that predators visit who even allow the wrasse into their mouths to clean their teeth.

Fish Extinction Crisis

Fishing, rising water demand, river dams, water pollution and invasive species place aquatic ecosystems among the most endangered on Earth. Therefore, the fact that many species of fish – both marine, and freshwater – are currently endangered, does not come as a surprise. More than one fifth of all known fish species are now considered to be at imminent risk.

FASCINATING FISH FACTS

THE BIGGEST

Fish range in size from the nearly microscopic to the gigantic. The longest fish is the whale shark at over 55 feet. The whale shark is also the heaviest, weighing 80,000 pounds.

THE SMALLEST

The smallest fish is the tiny stout infantfish at only 0.3 in.

THE FASTEST

The fastest fish is the swordfish, swimming at seeds of 40 mph.

THE LONGEST LIVED

European eels live the longest, well over 80 years.

SMART & SOCIAL

Fish have been proven to be as intelligent as mammals. They can distinguish between larger and smaller quantities and can count. Fish clean and massage one another by rubbing up against each others’ pectoral fins. They have advanced nervous systems that allow them to feel pain. They have highly-developed hearing capabilities that allow them to detect electric currents in the water, and can create their own electric currents. Archerfish fire jets of water to knock insects off foliage and into the water, requiring complex calculus calculations.

TOGETHER FOR LIFE

French angelfish mate for life and spend most of their time swimming together in their coral reef homes. When couples reunite after being separated, they joyfully encircle each other round-and-round in a romantic dance called "carouseling."

WORKING TOGETHER

Coral trout hunt in collaboration with moray eels. Cleaner wrasse perform rituals to coherce predators into letting them pick off parasites.

PROTECTIVE MOTHERS

Some fish protect their babies by opening their mouths and letting the babies swim inside until the predator has passed by.

TOOL USERS

Squid are very curious, have the ability to learn complex skills and use tools to repress their boredom and protect them from harm. They can change their body color and texture to not only blend in with their surroundings, but to convey different messages on both sides of their bodies, such as projecting a mating color on one side and warning off a predator on the other.

FRIENDS & FAMILY

Fish live in groups with social hierarchies. They are able to recognize individual family members, form bonds with other fish, cooperate and even tell time.

LOVERS OF MUSIC

Goldfish not only enjoy listening to music, but they also can distinguish one composer from another and detect complex properties of sounds, such as pitch and timbre. Goldfish can tell different faces apart and are able to distinguish between different shapes, colors and sounds.

FISH FEEL PAIN

While fish may have different brain structures than mammals, they do have nervous systems that comprehend and respond to pain. Numerous studies have proven that fish feel and react to pain. Without the ability to feel pain, it would be impossible for fish to survive. Pain perception is essential to animal survival and has deep evolutionary origins across all vertebrate species. Billions of fish are killed yearly for food in the U.S. alone, with no federal laws to protect fish from pain on aquaculture factory farms, during fishing events or at slaughter.

Elephants

Mon, 17 Nov 2025 01:09:00 +0000

ADOPT AN ELEPHANT

The elephant is the largest land mammal on earth and perhaps one of the most intelligent. The trunk of the elephant has two finger-like structures at its tip that allow the animal to perform both delicate and powerful movements. Its remarkable tusks first appear when the animal is two years of age and continue to grow throughout life. Elephants use tusks for peeling bark off trees, digging for roots, herding young, “drilling” for water and sometimes as a weapon.

Male African elephants reach a length of 18 to 21 feet and weigh up to 13,200 pounds. Females are about two feet shorter and weigh half as much.

Asian elephants are usually smaller than African elephants and have the highest body point on the head. Their backs are convex or level, and their ears are small with dorsal borders folded laterally. Their feet have more nail-like structures than those of African elephants—five on each forefoot, and four on each hind foot.

Elephants can live 50 to 60 years. Elephants are capable of surviving in nearly any habitat that has adequate quantities of food and water. They spend about 16 hours a day eating. Their diet is varied and includes grass, leaves, twigs, bark and fruit.

Elephants form deep family bonds and live in tight social units. A family is led by an older matriarch and typically includes three or four of her offspring and their young. Males leave the family unit between the ages of 12 and 15 and may lead solitary adult lives. Elephants live in a very structured social order.

The social lives of male and female elephants are very different. The females spend their entire lives in tightly knit family groups made up of mothers, daughters, sisters and aunts. These groups are led by the eldest female, or matriarch. Adult males, on the other hand, live mostly solitary lives. The social circle of the female elephant does not end with the small family unit. In addition to encountering the local males that live on the fringes of one or more groups, the female's life also involves interaction with other families, clans, and subpopulations. Most immediate family groups range from five to fifteen adults, as well as a number of immature males and females. When a group gets too big, a few of the elder daughters will break off and form their own small group. They remain very aware of which local herds are relatives and which are not.

The life of the adult male is very different. As he gets older, he begins to spend more time at the edge of the herd, gradually going off on his own for hours or days at a time. Eventually, days become weeks, and somewhere around the age of fourteen, the mature male, or bull, sets out from his natal group for good. While males do live primarily solitary lives, they will occasionally form loose associations with other males. These groups are called bachelor herds. The males spend much more time than the females fighting for dominance with each other. Only the most dominant males will be permitted to breed with cycling females. The less dominant ones must wait their turn. It is usually the older bulls, forty to fifty years old, that do most of the breeding. The dominance battles between males can look very fierce, but typically they inflict very little injury. Most of the bouts are in the form of aggressive displays and bluffs. Ordinarily, the smaller, younger, and less confident animal will back off before any real damage can be done. However, during the breeding season, the battles can get extremely aggressive, and the occasional elephant is injured. During this season, known as musth, a bull will fight with almost any other male it encounters, and it will spend most of its time hovering around the female herds, trying to find a receptive mate.

Elephant social life, in many ways, revolves around breeding and raising of the calves. A female will usually be ready to breed around the age of thirteen, at which time she will seek out the most fit male to mate with. Females carry their young for almost two years. At birth, the calf weighs about 250 pounds. A cow may give birth every three to four years.

Elephants have a very long childhood. They are born with fewer survival instincts than many other animals. Instead, they must rely on their elders to teach them the things they need to know. The ability to pass on information and knowledge to their young has always been a major asset in the elephant's struggle to survive. Today, however, the pressures humans have put on the wild elephant populations, from poaching to habitat destruction, mean that the elderly often die at a younger age, leaving fewer teachers for the young.

All members of the tightly knit female group participate in the care and protection of the young. Since everyone in the herd is related, there is never a shortage of baby sitters. In fact, a new calf is usually the center of attention for all herd members. All the adults and most of the other young will gather around the newborn, touching and caressing it with their trunks. The baby is born nearly blind and at first relies, almost completely, on its trunk to discover the world around it. After the initial excitement dies down, the mother will usually select several full time baby sitters, or "allomothers", from her group. They walk with the young as the herd travels, helping the calves along if they fall or get stuck in the mud. The more allomothers a baby has, the more free time its mother has to feed herself.

THREATS TO ELEPHANTS

Habitat loss and the ivory trade are the greatest threats to the elephants’ future. The threat to the African elephant presented by the ivory trade is unique to the species. Another threat to elephant's survival in general is the ongoing cultivation of their habitats with increasing risk of conflicts of interest with human cohabitants.

Lacking the massive tusks of its African cousins, the Asian elephant's demise can be attributed mostly to loss of its habitat. Elephants need massive tracts of land because, much like the slash and burn farmers, they are used to crashing through the forest, tearing down trees and shrubs for food and then cycling back later on, when the area has regrown. As forests are reduced to small pockets, elephants become part of the problem, quickly destroying all the vegetation in an area, eliminating all their resources.

Larger, long lived, slow breeding animals, like the elephant, are more susceptible to overhunting than other animals. They cannot hide, and it takes many years for an elephant to grow and reproduce.

Elephants in captivity lead miserable lives. In stark contrast to their natural tendency to roam several miles each day, they are bound in shackles and chains and forced to perform tasks that are the antithesis of their innate instincts. For a short time, it was illegal to capture a wild elephant for use in a circus or zoo, but the CITES decision in 1997 changed all of that. The training endured by circus animals is almost always based on intimidation; trainers must break the spirit of the animals in order to control them. It is not uncommon for an elephant to be tied down and beaten for several days while being trained to perform.

While zoos may appear to be educational and conservation-oriented, most are designed with the needs and desires of the visitors in mind, not the needs of the animals. Many animals in zoos exhibit abnormal behavior as a result of being deprived of their natural environments and social structures. Most animals in zoos were either captured from the wild or bred in captivity for the purpose of public display, not species protection.

Clownfish

Sat, 15 Nov 2025 01:12:00 +0000

ADOPT A CLOWNFISH

Clownfish, or Anemonefish, are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized. In the wild they are known for forming symbiotic relationships with sea anemones.

The most commonly known clownfish species is orange with white markings, but clownfish are found in many different colors and can also differ in shape. Depending on species, clownfish are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. The largest can reach a length of 7.1 inches, while the smallest barely reach 3.9 inches.

Clownfish are native to warmer waters of the Indian and Pacific oceans, including the Great Barrier Reef and the Red Sea. While most species have restricted distributions, others are distributed elsewhere. Clownfish live at the bottom of shallow seas in shallow reefs or lagoons. There are no clownfish in the Atlantic.

Clownfish are omnivorous and can feed on undigested food from their host anemones. The fecal matter from the clownfish provides nutrients to the sea anemone. Clownfish primarily feed on small zooplankton, with a small portion of their diet coming from algae.

Clownfish and sea anemones have a symbiotic, mutualistic relationship, each providing a number of benefits to the other. Sea anemones are a group of water-dwelling, predatory animals. A close relative of jellyfish and coral, they are stinging polyps that attach themselves with an adhesive foot to rocks on the sea bottom, or on coral reefs. They wait for fish to pass close enough to get ensnared in their venom-filled tentacles. Clownfish are immune to the anemone's sting, protected by a mucus layer.

The sea anemone protects the clownfish from predators, and provides food through scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators and parasites. The anemone also picks up nutrients from the clownfish's excrement, and functions as a safe nest site. The nitrogen excreted from clownfish increases the amount of algae incorporated into the tissue of their hosts, which aids the anemone in tissue growth and regeneration. The clownfish may use their bright coloring to lure small fish to the anemone, and provides greater water circulation around the sea anemone. Clownfish are the best known example of a fish that are able to live among the venomous sea anemone tentacles.

In a group of clownfish, there is a strict dominance hierarchy. The largest and most aggressive female is found at the top. Only two clownfish in a group, a male and a female, reproduce through external fertilization. Clownfish are sequential hermaphrodites, meaning that they develop into males first, and when they mature they become females. If the female clownfish is removed from the group, such as by death, one of the largest and most dominant males will become a female. The remaining males will move up a rank in the hierarchy.

Clownfish lay eggs on any flat surface close to their host anemones. They spawn around the time of the full moon. Depending on the species, clownfish can lay hundreds or thousands of eggs. The male parent guards the eggs until they hatch. In contrast to most animal species, the female only occasionally takes responsibility for the eggs. Male clownfish care for their eggs by fanning and guarding them for 6 to 10 days until they hatch. Eggs develop more rapidly in a clutch when males fan properly, suggesting that males have the ability to control the success of hatching an egg clutch by investing different amounts of time and energy towards the eggs.

THREATS TO CLOWNFISH

The biggest threats to the survival of clownfish are pollution, the commercial fishing industry and destruction of their habitat.

Clownfish are also victims of the pet trade and animal entertainment industry, making up 43% of the global marine ornamental trade and 25% of the global trade from fish bred in captivity...accounting for decreased densities in exploited areas. Captured from their native habitat and transported to various countries to be sold as aquarium "ornamentals", the dangers, difficulties, physical and physiological needs of the animals appears to be of no concern in the lucrative pet trade and animal entertainment industry. Removed from their natural habitat they are deprived of the ability to freely engage in instinctual behaviors. Even under the best of circumstances, captivity is cruel for fish. Confined to tiny tanks, captive fish endure constant stress and boredom. With little room to exercise, they become listless, their immune systems are weakened, and they become prone to sickness; many resort to self-mutilation in reaction to stress or boredom. Mental illness is rampant among confined animals. Members of some clownfish species become aggressive in captivity. Torn from their families and deprived of all dignity, every part of their lives is controlled by their captors. Clownfish in captivity live short lives, compared to clownfish in the wild.

Anemones are even more susceptible to overexploitation due to their long lifespans, slower relative growth rates, and lower reproductive rates than their resident fish. Aquarium fishing activities significantly impact the populations of anemones and anemonefish by drastically reducing the densities of each in exploited areas. They also negatively impact anemone shrimp, and any organisms associated with sea anemones.
