Snow Leopard


True Wild Life | Snow Leopard | The snow leopard  is a moderately large cat native to the mountain ranges of South Asia and Central Asia. Although sharing its name with the common leopard, the snow leopard is not believed to be closely related to the Leopard or the other members of the Pantherine group and is classified as the sole member of the genus Uncia uncia. The classification of this species has been subject to change and its exact taxonomic position will not be resolved until further studies are conducted.


Snow leopards live between 3,000 and 5,500 metres above sea level in the rocky mountain ranges of Central and South Asia. Their secretive nature means that their exact numbers are unknown, but it has been estimated that between 3,500 and 7,000 snow leopards exist in the wild and between 600 and 700 in zoos worldwide. 


Snow leopards are carnivores and actively hunt their prey, though, like all cats, they are opportunistic feeders, eating whatever meat they can find, including carrion and domestic livestock. The Snow Leopard eats goats, sheep, rabbits and birds. It can catch prey over 3 times its own weight!


At one time, the Snow Leopard was nearly hunted into disappearance for its fur. Its rare, beautiful fur could sell for a very high price. Now, conservation actions, for the Snow Leopard's numbers are slowly becoming popular. Sadly, the hunters kill the leopard for its fur, and some leopards are killed by people to protect domestic goats.

Iberian Lynx


True Wild Life | Iberian Lynx | The Iberian lynx also known as Spanish lynx is a critically endangered species native to the Iberian Peninsula in Southern Europe. It is one of the most endangered cat species in the world. The species used to be classified as a subspecies of the Eurasian Lynx, but is now considered a separate species. Both species occurred together in central Europe in the Pleistocene epoch, being separated by habitat choice. Iberian lynx resembles other species of lynx, with a short tail, tufted ears and a ruff of fur beneath the chin. Iberian lynx has leopard-like spots with a coat that is often light grey or various shades of light brownish-yellow. The coat is also noticeably shorter than in other lynxes, which are typically adapted to colder environments.


In spite of its strong resemblance to the Eurasian Lynx, the Iberian Lynx has a smaller body and the facial features of a house cat. Iberian lynx typically hunts smaller animals, usually no larger than hares. It also differs in habitat choice, with Iberian lynx inhabiting open scrub and Eurasian lynx inhabiting forests.


The Iberian Lynx must really like rabbit because it accounts for an amazing 80% of their diet. They also eat young deer and duck. At one time, rabbits disappeared due to an epidemic outbreak and the number of Iberian Lynx plummeted. This is because rabbits are its main food. Today, development continues to destroy forest environments and could trigger another decline in rabbits. If that happens, it will cause irreparable damage to the already scarce population of Iberian Lynx.


There are only a few forests in Spain and Portugal where the remaining Iberian Lynx live, making them one of the most critically endangered species of the Felidae family. Forest development is one of the main reasons they have become so rare. Their habitat has diminished and they live sporadically due to roads and towns being built in the forest. Further damage comes from poachers who continue to violate bans on their hunting.

Ryukyu Tip-Nosed Frog


True Wild Life | Ryukyu Tip-Nosed Frog | The Ryukyu Tip-Nosed Frog is a species of frog in the Ranidae family. It is endemic to Japan. Ryukyu Tip-Nosed Frogs only live in the northern main island of Okinawa. Not like the other frogs, Ryukyu Tip-Nosed Frogs have nostrils at the tip of their faces. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss. Ryukyu Tip-Nosed Frogs enjoy eating small bugs or centipedes, and some shellfishes on the land.

Now, the forests that Ryukyu Tip-Nosed Frogs need for living became smaller because people cut down trees to build dams and roads. Many people come to see rare Ryukyu Tip-Nosed Frogs with their own eyes, but their visits hurt the environment. Exotic animals in Okinawa can adapt to the changes in nature. But they are not comfortable living with dams or roads, and being gazed by humans.

Ishikawa's Frog


True Wild Life | Ishikawa's Frog | Ishikawa's Frog is the most beautiful frog in Japan. Forests are disappearing and rivers are becoming dirty. Ishikawa's frog is in danger. Amphibians have trouble changing when their environment changes. They have a purple and green pattern that looks like moss. It hides them from their enemies.


The population of Okinawajima is designated as a natural monument by Okinawa and Kagoshima Prefectures, but there remains a need for improved protection of forest habitat on both Okinawajima and Amamioshima.


Ishikawa's Frog only lives on Okinawa's main island, and is a very special frog. Some people believe they are Japan's most beautiful frog. Ishikawa's Frog needs small mountain streams in forests to live. However, forests are disappearing and rivers are becoming dirty. Ishikawa's Frog cannot live safely. Their numbers are becoming smaller, and we worry about their disappearance in the future. To stop the disappearance of Ishikawa's Frog, severe rules about catching and caring for them were made. But, that's not enough to save Ishikawa's Frog. Frogs are amphibians, and are very sensitive to changes in environment. We must give back the rivers, forests, and the surrounding nature to Ishikawa's Frog.

Goliath Frog


True Wild Life | Goliath Frog | The Goliath Frog is the biggest frog in the world. They have been popular as food from a long time ago. They are also caught to keep as pets or for their skin, and their numbers have gone down to half of what they were before. This animal has a relatively small habitat range, mainly in Cameroon and Equatorial Guinea. Its numbers are dwindling due to habitat destruction, its collection for consumption as food and its collection for the pet trade.


The goliath frog is normally found in and near fast-flowing rivers with sandy bottoms in the West African countries of Cameroon and Equatorial Guinea. These rivers are usually clear and highly oxygenated. Their actual range spans from the last 200 km of the Sanaga basin in Cameroon to the north to the last 50 km  of the Benito River basin in Equatorial Guinea to the south. The river systems in which these frogs live are often found in dense, extremely humid areas with relatively high temperatures. The goliath frog can live up to 15 years in the wild. In captivity, they can live up to 21 years. While male Goliath frogs weigh up to 8 pounds, females can weigh up to 7. These frogs have acute hearing but no vocal sac, and additionally lack nuptial pads.


The goliath frog, like most frogs, feed on worms, and insects, such as dragonflies and locusts. Bees and wasps could be prey, but since they have stingers they use as a weapon, the goliath frog rarely even catch one. Goliath Frogs also eat smaller frogs, largely crabs, baby turtles, and young snakes. The goliath frog is also preyed on by snakes, Nile crocodiles and Nile monitors.


Like all amphibians the water is vital for their reproduction. The males will construct spawning and breeding areas alongside and within rivers by pushing rocks into semicircular patterns. Not much is known about the goliath frog's reproduction; however, some African scholars have started to do more research for medical reasons. They are the biggest frogs in the world. As tadpoles they are pretty small, and become frogs about 1.4cm in length. Once they become frogs they get bigger little by little.

The increase of people in the Goliath Frog's living space has become a problem. First, the spaces where they can live have become fewer. Also, Goliath Frogs are skilled swimmers and live near rivers. Because of people, the rivers have started to get dirtier, and the frogs are no longer able to live in a safe environment like before.

Golden Poison Frog


True Wild Life | Golden Poison Frog | The Golden Poison Frog is the most poisonous animal in the world. Unfortunately, they are on the brink of extinction because tropical rainforests are disappearing. The golden poison Frog's skin is densely coated in alkaloid poison, one of a number of poisons common to dart frogs  which prevents nerves from transmitting impulses, leaving the muscles in an inactive state of contraction. This can lead to heart failure or fibrillation.


The Golden Poison Frog's natural enemy is a genus of snakes called the Leimadophis Epinephelus. These snakes are unaffected by the lethal poison of the Golden Poison Frog. The Golden Frog lives on the ground in humid forests, and is only known from primary forest. It is not known whether or not it can adapt to secondary habitats. The eggs are laid on the ground and the males transport the larvae to permanent pools.  The main natural sources of food of Golden Poison Frogs are the ants in the genera Brachymyrmex and Paratrechina, but many kinds of insects and other small invertebrates can be devoured, specifically termites and beetles, which can easily be found on the rainforest floor. This frog is considered the most voracious of the dendrobatids.


In captivity, the frog is fed with Drosophila fruit flies, cochineals and crickets, the larvae of various insects, and other small live invertebrate foods. An adult frog can eat food items much larger in relation to its size than most other dendrobatids. Golden Poison Frog is a very important frog to the local indigenous cultures, such as the Choco Emberá people in Colombia's rainforest. The frog is the main source of the poison in the darts used by the natives to hunt their food. The Emberá people carefully expose the frog to the heat of a fire, and the frog exudes small amounts of poisonous fluid. The tips of arrows and darts are soaked in the fluid, and keep their deadly effect for over two years.


In many ways, humans have benefited from the Golden Poison Frog. Yet today, the wild frogs are in danger of extinction. They live in only certain parts of tropical rainforests that are disappearing as deforestation and farm land development continues in various parts of the world.

Przewalski's Horse


True Wild Life | Przewalski's Horse | The Przewalski's Horse is the only remaining wild horse still surviving in the world. Once, it became extinct because it was hunted or it lost in the feeding frenzy with farm animals. Przewalski's Horse is a rare and endangered subspecies of wild horse  native to the steppes of central Asia, specifically China and Mongolia. At one time extinct in the wild, it has been reintroduced to its native habitat in Mongolia at the Khustain Nuruu National Park, Takhin Tal Nature Reserve and Khomiin Tal.


In the wild, Przewalski's Horses live in social groups consisting of a dominant stallion, a dominant lead mare, other mares, and their offspring. The patterns of their daily lives exhibit horse behavior similar to that of feral horse herds. Each group has a well-defined home range; within the range, the herd travels between three and six miles a day, spending time grazing, drinking, using salt licks and dozing. At night, the herd clusters and sleeps for about four hours. Ranges of different herds may overlap without conflict, as the stallions are more protective of their mares than their territory.


With a short, muscular body, Przewalski’s horses are smaller than most domesticated horses. They have a pale belly and beige to reddish-brown coat that is short during summer and thicker and longer in winter. Their muzzle is white, and they don an erect and dark mane that lines their large head and neck. They stand about 12 to 14 hands tall at the shoulder, or about 48 to 56 inches (122 to 142 centimeters), and weigh about 440 to 750 pounds (200 to 340 kilograms). While extant in the wild, these horses ate grasses and other vegetation on the steppe, shrublands, and plains of western Mongolia and northern China.


In the 1960s, Przewalski's Horses disappeared once. They were hunted for their meat and hide. Others lost in the feeding frenzy with farm horses. In the 1990s, a project started to return Przewalski's Horses to the wild. Zoos in Europe raised Przewalski's Horses and returned them to wildlife sanctuaries in hometown, Mongolia, and the number of Przewalski's Horses in the wild is starting to increase, little by little.

Mountain Zebra


True Wild Life | Mountain Zebra | The Mountain Zebra is an endangered species of equid native to south-western Angola, Namibia and South Africa. It has two subspecies, the Cape Mountain Zebra  and Hartmann's Mountain Zebra, though it has been suggested these should be considered separate species. Like all zebras, it is boldly striped in black and white and no two individuals look exactly alike. The stripe can be black and white or dark brown and white. Their stripes cover their whole bodies except for their bellies. The Mountain zebra also has a dewlap.


As its name suggests, the Mountain Zebra lives in higher places than other zebras. Its numbers are decreasing because of hunting for its skin and meat, and also because of droughts. Mountain Zebras are found on mountain slopes, open grasslands, woodlands and areas with sufficient vegetation. Some Mountain Zebras live in the rainforest. Mountain zebras live in hot, dry, rocky, mountainous and hilly habitats. They prefer slopes and plateaus and can be found as high as 1,000 metres above sea level, although they do migrate lower in the winter season. Their diet consists of tufted grass, bark, leaves, buds, fruit and roots. They often dig for ground water.


Mountain zebra are most active in the early morning and late afternoon. They spend up to half of the daylight hours feeding. Mountain zebra live in herds consisting of one adult male (stallion), one to five adult females (mares) and their young. The stallion is the dominant member of the herd. Sometimes herds come together to form temporary groups of up to 30 individuals. Mountain zebra never form the large herds characteristic of Plains zebra, however, they do exhibit a harem-type social system. During the winter they move up to 20 kilometres from a water source. Where they are in danger of being hunted, Mountain zebra water at night, however, when they are not in danger of being hunted, they water at any time.


The Mountain zebras form small family groups consisting of a single stallion, one, two, or several mares, and their recent offspring. Bachelor males live in separate groups and attempt to abduct young mares and are opposed by the stallion. Mountain zebra groups do not aggregate into large herds like Plains zebras. Mares may give birth to one foal every twelve months. Like other equids, zebra foals are able to stand, walk and suckle shortly after they are born. The mare nurses the foal for up to a year, and the young zebra then leave to join bachelor groups or harems.


The Mountain Zebra lives in higher places than any other zebra. It lives in two different locations in southwestern Africa and South Africa. The biggest threat to Mountain Zebras is hunting by people. These animals have long been hunted for their beautifully patterned skins and meat. The Mountain Zebras that live in South Africa have nearly been wiped out twice in the past.

Grevy's Zebra


True Wild Life | Grevy's Zebra | The Grevy's zebra , also known as the Imperial zebra, is the largest extant wild equid and one of three species of zebra, the other two being the plains zebra and the mountain zebra. The Grevy's zebra is found in Kenya and Ethiopia. Compared with other zebras, it is tall, has large ears, and its stripes are narrower. It is more ass-like in appearance as compared to other zebras, which are more horse-like. Among their kinds who were hunted for their hides, Grevy's Zebra is the largest kind of zebra. The Grevy's Zebra's pattern is like a painting, so it is called the most beautiful of zebras. However, its beauty is its sadness, because it is hunted for its hide. Its numbers keep becoming lower and lower.


Grevy's zebras grow up to nine feet long, weigh up to 990 pounds, and stand up to almost five and a half feet at the shoulder. On average, males are about ten percent larger than females. Big heads, large and rounded ears, and thick, erect manes make the Grevy's zebra appear more mule-like than other zebras. In fact, many experts consider Grevy's zebras to be striped asses that are not closely related to other zebras. Their coats sport dazzling narrow stripes that wrap around each other in a concentric pattern and are bisected by a black stripe running down the spine. Grevy's Zebra is hunted for its beautiful hide and so it has had a shocking drop in numbers.


Males are highly territorial, claiming prime watering and grazing areas with piles of dung called middens. They generally live alone in their territories, except when females move through during mating season. Non-territorial males travel together in groups of two to six animals. This social system differs from that of other zebras, which typically form female harems that live in one male's territory all year. During dry months, many Grevy's zebras migrate to greener mountain pastures, but males on prime territories often remain there year-round. Grevy's zebras inhabit semi-desert areas, including arid grasslands and dusty acacia savannas. The most suitable areas have water year-round.


Normally only one foal is born to a female after a gestation period of thirteen months. Most of the babies are born between May and August. The young zebra has brown stripes and a mane which stretches from the shoulder to the tail. The background colour of the foal's coat is light brown instead of white. This protective colouring helps the foal to "freeze" and blend instantly with its background. The foal can stand on its feet within one hour of its birth and can run with the herd after only a few hours - this gives it a much better chance of escaping from predators, usually lions. Young males leave the herd when they are about two years old and join bachelor herds. Eventually they will collect mares to form their own new herds or perhaps challenge old or weak stallions and take over their herd.


Today, the surviving wild Grevy's Zebras are protected in national parks. The Grevy's Zebra has other things to worry about. Domesticated animals are growing in number, and the grass that the zebra eats has been taken away. Its living space is also disappearing because people are building. Experts speculate there are only around 1,900 to 2,500 wild Grevey's Zebras left.

Asian Wild Ass

 
True Wild Life | Asian Wild Ass | The Asian Wild Ass was once considered to be among the largest population of ungulates, along with horses, cows, camels, and deer. Herds of 1,000 or more Asian Wild Asses have often been observed in Central and West Asia. Like many other large grazing animals, the asian wild ass' range has contracted greatly under the pressures of hunting and habitat loss, and of the six subspecies, one is extinct and two are endangered. The kiang , a Tibetan relative, was previously considered to be a subspecies of the asian wild ass as E. hemionus kiang, but recent molecular studies indicate that it is a distinct species. 


Asian Wild Ass are a little larger than donkeys at about 290 kilograms  and 2.1 metres , and are a little more horse-like. They are short-legged compared to horses, and their coloring varies depending on the season. They are generally reddish-brown in color during the summer, becoming yellowish-brown in the winter months. They have a black stripe bordered in white that extends down the middle of the back. They are notoriously untameable.


The Asian Wild Ass lives in the grasslands and deserts of Central and West Asia.Most people associate a donkey with a slow moving animal, but the Asian Wild Ass is one of the fastest running asses in the horse family. They can run 70 kilometers or more per hour in short spurts.


Today, the Asian Wild Ass is on the brink of extinction. This is partially due to the expansion of grazing land. Livestock animals have taken over their grassland and watering areas. But it is also because of an expansion of farmlands which has shrunk their habitat and forced them to separate. No longer is it possible to see herds of 1,000 asses. Conservation efforts have helped them recover their population in some areas, but as a whole, the Asian Wild Ass is still an endangered species.

African Wild Ass


True Wild Life | African Wild Ass | The African Wild Ass is a wild member of the horse family, Equidae. This species is believed to be the ancestor of the domestic donkey which is usually placed within the same species. They live in the deserts and other arid areas of northeastern Africa, in Eritrea, Ethiopia and Somalia; it formerly had a wider range north and west into Sudan, Egypt and Libya. About 570 individuals exist in the wild. The African Wild Ass is suited for life in the desert, capable of going on for up to three days without drinking water.


African wild asses are well suited to life in a desert or semidesert environment. They have tough digestive systems, which can break down desert vegetation and extract moisture from food efficiently. They can also go without water for a fairly long time. Their large ears give them an excellent sense of hearing and help in cooling. Because of the sparse vegetation in their environment wild asses live somewhat separated from each other (except for mothers and young), unlike the tightly grouped herds of wild horses. They have very loud voices, which can be heard for over 3 km, which helps them to keep in contact with other asses over the wide spaces of the desert.

The African Wild asses can run swiftly, almost as fast as a horse. However, unlike most hoofed mammals, their tendency is to not flee right away from a potentially dangerous situation, but to investigate first before deciding what to do. When they need to, they can defend themselves with kicks from both their front and hind legs. The African Wild Ass eats plant material, often eating thorn bushes and tougher plants that other animals ignore. They need to have water at least every three days, but they are able to survive on water that is dirty and brackish and can get a lot of their moisture from the plant material that they eat.


Sexual maturity of the female ass usually happens by the time she reaches two. Males can also reproduce at two, but it is so competitive that they usually are forced to wait until they are around four. Males are very territorial and will often hold a huge territory that is about 23 km, and they mark the edges of their territories with dung. Other males are allowed in, but they are kept away from the females as much as possible. Male donkeys will bray when the females are in season, and a dominant male of a territory has first right to breed with any female that comes around. The gestational period usually lasts 11-12 months, and the females in the wild usually give birth only once every two years. The young are weaned at about six months of age, and the animals can live approximately 40 years.


In addition to their struggle with domesticated livestock to secure food and water, the African Wild Ass also became a hunted animal for consumption and medicine. Many dangerous weapons found their way into the homeland of the African Wild Ass due to the war between Ethiopia and Eritrea. There is a concern that these weapons will be used more often from now on to hunt more of the African Wild Ass. Currently, there is a protection program in progress to move the African Wild Ass into a protected area of Israel.

Quokka


True Wild Life | Quokka | The Quokka is a small macropod about the size of a domestic cat. Like other marsupials in the macropod family , the Quokka is herbivorous and mainly nocturnal. It can be found on some smaller islands off the coast of Western Australia, in particular on Rottnest Island just off Perth and Bald Island near Albany. Quokkas resemble a small wallaby, with small rounded ears, and brown or greyish fur.


In the wild, its roaming is restricted to a very small range in the South-West of Western Australia, with a number of small scattered populations on the mainland, one large population on Rottnest Island and a smaller population on Bald Island near Albany. The islands are free of foxes and cats. On Rottnest, it is common and occupies a variety of habitats ranging from semi-arid scrub to cultivated gardens.


Quokka weighs 2.5 to 5 kg and is 40 to 90 cm long with a 25 to 30 cm tail  which is rather short for a macropod. It has a stocky build, rounded ears, and a short, broad head. Although looking rather like a very small, dumpy kangaroo, it can climb small trees and shrubs. Its coarse fur is a grizzled brown colour, fading to buff underneath.


Quokka feeds at night on native grasses and the leaves of shrubs. They need drinking water, but can survive long periods without it. This is helped by the remarkable ability of the Quokka to reuse a portion of their bodies waste products. These animals breed year round, and have a gestation period of 4 months before a new joey is born. The joey lives in its mother's pouch for the first 25 weeks of its life. After leaving the pouch, the joey continues to suckle at its mother's teets for a further 10 weeks.


There were once a lot of Quokkas, but they are now in danger of extinction. They are under threat from development that has destroyed the wetlands where they live and are also threatened by other animals that have been introduced by humans. Quokkas are preyed on by cats and foxes, who are non-native animals in Australia. Their wetland habitat is also disturbed by feral pigs. While efforts are being made to protect them, it is thought that the numbers of Quokka still have not recovered.

Huon Tree Kangaroo


 
True Wild Life | Huon Tree Kangaroo | Huon Tree Kangaroo (Dendrolagus matschiei), also known as the Matschie's Tree Kangaroo is a tree kangaroo  native to the Huon Peninsula of North Eastern New Guinea. Under the IUCN classification, Huon Tree Kangaroo is endangered. With a body and head length of 20 to 32 inches, Huon Tree Kangaroo are much smaller than Australia's well-known red kangaroo. 


There is no particular season in which they breed. Gestation lasts 32 days and joeys of captive bred individuals leave the pouch after 13 ½ months. The average life span of the Huon Tree Kangaroo in the wild is unknown, but is at least 14 years. The life span of the kangaroo in a zoo is about 20 years. The Huon Tree Kangaroo can only be found on the Huon Peninsula on the northeast coast of Papua New Guinea. They live in forests that are usually foggy.Unlike other species of kangaroos, the Huon Tree Kangaroo spends most of its time living in trees. They even eat and sleep in trees.


The most distinctive trait of all tree kangaroos is the hair whorl they possess. It is a patch of hair that goes out in many directions and its location ranges from up near the shoulders all the way down to the tail. The Huon Tree Kangaroo is golden on its ventral side, lower parts of its limbs, ear edges, belly, and tail, and the rest of its body is a chestnut brown color, except for usually having a dark stripe down its back. Their faces are typically an array of yellow and white colors. The Huon Tree Kangaroos are similar in color and size to Dendrolagus dorianus, the Doria’s tree kangaroo. Huon Tree Kangaroos ears are small and bear-like looking and they do not have a good sense of hearing because of it. They have curved claws on their forelimbs and soft pads on their hind limbs that aid in their climbing ability, and they have some independent movement of their digits as well as good dexterity due to their forelimbs being able to bend a great deal.


The Huon Tree Kangaroo are mainly folivorous, eating anything from leaves, sap, insects, flowers, and nuts.  Since they eat high fiber foods, they only eat maybe about 1 to 2 hours throughout the day and the other time of the day they are resting and digesting their food. Their digestion is similar to that of the ruminants; they have a large, “tubiform forestomach”, where most of the fermentation and breakdown of tough material takes place at; in the hind stomach, there is a mucosa lining with many glands that help absorption begin here.


The Huon Tree Kangaroo lives only on the Huon Peninsula of Papua New Guinea. Usually we think of kangaroos as animals that hop around grasslands. However, Huon Tree Kangaroos are an exception. They live in forests and are more adept at climbing trees than they are at moving on land. Today, as the population on the Huon Peninsula grows, more and more of the kangaroo's precious forests are being converted into farmland. Continued habitat loss is pushing the Huon Tree Kangaroo toward the brink of extinction.
