Waterbuck

The Waterbuck (Kobus ellipsiprymnus) is an antelope found in Western, Central Africa, East Africa and Southern Africa.

Waterbuck stand 100 to 130 centimetres at the shoulder and weigh from 160 to 240 kilograms. Their coats are reddish brown in colour and become progressively darker with age; they also have a white 'bib' under their throats and a white ring on their rumps surrounding their tails. The waterproofing secretions of the waterbuck's sweat glands produces an unpleasant odor in its meat. The long spiral structured horns, found only in males, sweep back and up.

Waterbuck are found in scrub and savanna areas near water where they eat grass. Despite its name, the waterbuck does not spend much time in the water, but will take refuge there to escape predators. Waterbuck are diurnal. Females gather in herds of between two and six hundred individuals. Males keep territories of around three hundred acres (1.2 km²) during their prime. They usually lose their territories before the age of ten.

The Defassa Waterbuck is a subspecies (Kobus ellipsiprymnus defassa) in which the ring on the rump is solid white.

Western Lowland Gorilla

The Western Lowland Gorilla (Gorilla gorilla gorilla) is a subspecies of the Western GorillaGorilla gorilla) that lives in montane, primary, and secondary forests and lowland swamps throughout all or parts of Angola, Cameroon, Central African Republic, Congo, Democratic Republic of the Congo, Equatorial Guinea and Gabon. Of all gorillas it is the gorilla usually found in zoos. (

A male Western Lowland Gorilla can stand 6 feet tall and weigh almost 450 lbs.

The Western Lowland Gorilla eats plants and, occasionally, insects. They live in family groupings consisting of one dominant male, 5 to 7 adult females, children and adolescents, and possibly a few non-dominant males.

Adult male Gorillas are prone to a particular form of cardiomyopathy, a degenerative heart disease. Babec, a Western Lowland Gorilla on exhibit at the Birmingham Zoo in Birmingham, Alabama (USA) was the first gorilla to receive an artificial pacemaker.

The Western Lowland Gorilla is critically endangered due to the Ebola virus and their main predators: man (poachers) and leopards.

Wolverine ( Gulo luscus )

Wolverine
Genus: Gulo
Species: luscus

The Taiga Biome is populated with special animals that all have techniques of keeping warm and dry or away from the harsh coldness of the Taiga. One animal of the Taiga is the wolverine. The wolverine is a meat eating animal, or carnivore. It's body length can get up to 87 centimeters as an adult and weigh about 45 lbs. It looks sort of like a bear, with short legs, but it is the largest member of the weasel family. The wolverine is powerfully built and is well adapted to living in the cold. It has very strong jaws that can bite through frozen meat and bone. Its head is wide and kind of rounded, with small eyes and small

round ears. Its paws are very large with long claws. The wolverine's fur is thick and a glossy dark brown.

It is known for it's physical strength and sharp, accurate hunting skills. It ranges from western United States, through Canada, up to Alaska. Wolverines have a very keen sense of smell that helps it locate food. It feeds mostly on rodents, fish, reptiles, birds, carrion, and sometimes berries. It's habitat is in the boreal forests of the northern North American continent.

During breeding season the males usually stay close to the female, but they prefers to travel alone. The females give birth to about 2 to 3 kits in March. The kits are born furry and their eyes are closed. They are weaned in about 9 to 10 months. They reach adult size by early winter but may stay with their mother until they are old enough to reproduce.

The wolverines need a large home territory of about 200 square miles. They need lots of shelters in rock crevices and among boulders to hole up during bad weather or to escape predators. Its huge, flat feet and long claws make the wolverine an excellent climber. Their feet also act as snowshoes and keep them from sinking into deep snow.

The wolverine is a shy animal that tries to avoid contact with humans. Human settlements and low birth rates have decreased the wolverine populations in North America. Wolverines are considered a rare and vulnerable species.

Elephant

Elephants (Elephantidae) are a family in the order Proboscidea in the class Mammalia. They were once classified along with other thick skinned animals in a now invalid order, Pachydermata. There are three living species: the African Bush Elephant, the African Forest Elephant (until recently known collectively as the African Elephant), and the Asian Elephant (also known as the Indian Elephant). Other species have become extinct since the last ice age, which ended about 10,000 years ago, the Mammoth being the most well-known of these.

Elephants are mammals, and the largest land animals alive today. The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kilograms (265 lb). An elephant may live as long as 70 years, sometimes longer. The largest elephant ever recorded was shot in Angola in 1956. This male weighed about 12,000 kg (26,400 lb), with a shoulder height of 4.2 m (13.8 ft), a metre (3 ft 4 in) taller than the average male African elephant. The smallest elephants, about the size of a calf or a large pig, were a prehistoric species that lived on the island of Crete during the Pleistocene epoch.

Elephants are symbols of wisdom in Asian cultures, and are famed for their memory and high intelligence, and are thought to be on par with cetaceans and hominids. Aristotle once said the elephant was "the beast which passeth all others in wit and mind."

Elephants are increasingly threatened by human intrusion and poaching. Once numbering in the millions, the African elephant population has dwindled to between 470,000 and 690,000 individuals. The elephant is now a protected species worldwide, with restrictions in place on capture, domestic use, and trade in products such as ivory. Elephants generally have no natural predators, although lions may take calves and occasionally adults. In some areas, lions may regularly take to preying on elephants.

The word "elephant" has its origins in the Greek ἐλέφας, meaning "ivory" or "elephant".

Species

The African Elephant genus contains two (or, arguably, three) living species; whereas, the Asian Elephant species is the only surviving member of its genus, but can be subdivided into four subspecies.

African elephants, at up to 4 m (13 ft 1 in) tall and weighing 7500 kg (8.27 short tons), are usually larger than the Asian species and they have bigger ears. Both male and female African elephants have long tusks, while their Asian counterparts have shorter ones, with those of females vanishingly small. African elephants have a dipped back, smooth forehead and two "fingers" at the tip of their trunks, whereas the Asian have an arched back, two humps on the forehead and only one "finger" at the tip of their trunks.

African elephants are further subdivided into two populations, the Savanna and Forest, and recent genetic studies have led to a reclassification of these as separate species, the forest population now being called Loxodonta cyclotis, and the Savanna (or Bush) population termed Loxodonta africana. This reclassification has important implications for conservation, because it means that where previously it was assumed that a single and endangered species comprised two small populations, if in reality these are two separate species, then as a consequence, both could be more gravely endangered than a more numerous and wide-ranging single species might have been. There is also a potential danger in that, if the forest elephant is not explicitly listed as an endangered species, poachers and smugglers might be able to evade the law forbidding trade in endangered animals and their body parts.

The Forest elephant and the Savanna elephant can hybridise – that is, breed together – successfully, though their preferences for different terrains reduce such opportunities. As the African elephant has only recently been recognized to comprise two separate species, groups of captive elephants have not been comprehensively classified and some could well be hybrids.

Successful hybridisation between African and Asian Elephant species is much more unlikely, as is animal hybridization across different genera in general. In 1978, however, at Chester Zoo, an Asian elephant cow gave birth to a hybrid calf sired by an African elephant bull (the old terms are used here as these events pre-date the current classifications). "Motty", the resulting hybrid male calf, had an African elephant's cheeks, their ears (large with pointed lobes) and legs (longer and slimmer), but the toenail numbers, (5 for each front foot, 4 hind) and the single trunk finger of an Asian elephant. His wrinkled trunk was like that of an African elephant. His forehead was sloping with one dome and two smaller domes behind it. The body was African in type, but had an Asian-type centre hump and an African-type rear hump. The calf died of infection 12 days later. It is preserved as a mounted specimen at the British Natural History Museum, London. There are unconfirmed rumours of three other hybrid elephants born in zoos or circuses; all are said to have been deformed and none survived.

African Elephant

The Elephants of the genus Loxodonta, known collectively as African elephants, are currently found in 37 countries in Africa.

African elephants are distinguished from Asian elephants in several ways, the most noticeable being their ears. Africans' ears are much larger and are shaped like the continent of their origin. The African is typically larger than the Asian and has a concave back. Both African males and females have external tusks and are usually less hairy than their Asian cousins.

African elephants have traditionally been classified as a single species comprising two distinct subspecies, namely the savanna elephant (Loxodonta africana africana) and the forest elephant (Loxodonta africana cyclotis), but recent DNA analysis suggests that these may actually constitute distinct species. While this split is not universally accepted by experts a third species of African elephant has also been proposed.

Under the new two species classification, Loxodonta africana refers specifically to the Savanna Elephant, the largest of all elephants. In fact, it is the largest land animal in the world, standing up to 4 m (13 ft) at the shoulder and weighing approximately 7,000 kg (7.7 tons). The average male stands about 3 m (10 ft) tall at the shoulder and weighs about 5500–6000 kg (6.1–6.6 tons), the female being much smaller. Most often, Savanna Elephants are found in open grasslands, marshes, and lakeshores. They range over much of the savanna zone south of the Sahara.

The other postulated species is the Forest Elephant (Loxodonta cyclotis). Compared with the Savanna Elephant, its ears are usually smaller and rounder, and its tusks thinner and straighter and not directed outwards as much. The Forest Elephant can weigh up to 4,500 kg (10,000 lb) and stand about 3 m (10 ft) tall. Much less is known about these animals than their savanna cousins because environmental and political obstacles make them difficult to study. Normally, they inhabit the dense African rain forests of central and western Africa, though occasionally they roam the edges of forests and so overlap the territories of the Savanna elephants and breed with them. In 1979, Iain Douglas-Hamilton estimated the continental population of African elephants at around 1.3 million animals. This estimate is controversial and is believed to be a gross overestimate, but it is very widely cited and has become a de facto baseline that continues to be incorrectly used to quantify downward population trends in the species. Through the 1980s, Loxodonta received worldwide attention due to the dwindling numbers of major populations in East Africa, largely as a result of poaching. Today, according to IUCN’s African Elephant Status Report 2007 there are approximately between 470,000 and 690,000 African elephants in the wild. Although this estimate only covers about half of the total elephant range, experts do not believe the true figure to be much higher, as it is unlikely that large populations remain to be discovered. By far the largest populations are now found in Southern and Eastern Africa, which together account for the majority of the continental population. According to a recent analysis by IUCN experts, most major populations in Eastern and Southern Africa are stable or have been steadily increasing since the mid-1990s, at an average rate of 4.5% per annum.

Elephant populations in West Africa, on the other hand, are generally small and fragmented, and only account for a small proportion of the continental total. Much uncertainty remains as to the size of the elephant population in Central Africa, where the prevalence of forest makes population surveys difficult, but poaching for ivory and bushmeat is believed to be intense through much of the region.

Asian Elephant

The Asian elephant is smaller than the African. It has smaller ears, and typically, only the males have large external tusks.

"O Elephante" - Hand-coloured engraving drawn by H.Gobin and engraved by Ramus - Printed in France by the "Lamoureaux de Paris" and Published for Magalhães e Moniz Editores in Portugal - 1890 (From the Dr. Nuno Carvalho de Sousa Private Collections - Lisbon)

The world population of Asian elephants – also called Indian Elephants or Elephas maximus – is estimated to be around 60,000, about a tenth of the number of African elephants. More precisely, it is estimated that there are between 38,000 and 53,000 wild elephants and between 14,500 and 15,300 domesticated elephants in Asia with perhaps another 1,000 scattered around zoos in the rest of the world. The Asian elephants' decline has possibly been more gradual with the causes primarily being poaching and habitat destruction by human encroachment.

There are several subspecies of Elephas maximus and some have been identified only using molecular markers. The first found subspecies is the Sri Lankan Elephant (Elephas maximus maximus). Found only on the island of Sri Lanka, it is the largest of the Asians. There are only an estimated 3,000–4,500 members of this subspecies left today in the wild, although no accurate census has been carried out in the recent past. Large males can weigh upward to 5,400 kg (12,000 lb) and stand over 3.4 m (11 ft) tall. Sri Lankan males have very large cranial bulges, and both sexes have more areas of depigmentation than are found in the other Asians. Typically, their ears, face, trunk, and belly have large concentrations of pink-speckled skin. There is an orphanage for elephants in Pinnawala Sri Lanka, which gives shelter to disabled, injured elephants. This program plays a large role in protecting the Sri Lankan Elephant from extinction.

Elephant In Sri Lanka

Another subspecies, the Indian Elephant (Elephas maximus indicus) makes up the bulk of the Asian elephant population. Numbering approximately 36,000, these elephants are lighter grey in colour, with depigmentation only on the ears and trunk. Large males will ordinarily weigh only about 5,000 kg (11,000 lb) but are as tall as the Sri Lankan. The mainland Asian can be found in 11 Asian countries, from India to Indonesia. They prefer forested areas and transitional zones, between forests and grasslands, where greater food variety is available.

The smallest of all the elephants is the Sumatran Elephant (Elephas maximus sumatranus). Population estimates for this group range from 2,100 to 3,000 individuals. It is very light grey and has less depigmentation than the other Asians, with pink spots only on the ears. Mature Sumatrans will usually only measure 1.7–2.6 m (5.6–8.5 ft) at the shoulder and weigh less than 3,000 kg (6,600 lb). An enormous animal nonetheless, it is considerably smaller than its other Asian (and African) cousins and exists only on the island of Sumatra, usually in forested regions and partially wooded habitats.

In 2003 a further subspecies was identified on Borneo. Named the Borneo pygmy elephant, it is smaller and tamer than other Asian elephants. It also has relatively larger ears, longer tail and straighter tusks.

Cheetah

The cheetah (Acinonyx jubatus) is a member of the cat family (Felidae) that is unique for making up in speed and stealth what it lacks in climbing abilities. As such, it is placed in its own genus, Acinonyx. It is the fastest of all land animals and can reach speeds between 112 kilometres per hour (70 mph) and 120 kilometres per hour (75 mph) in short bursts up to 460 metres (500 yd), and has the ability to accelerate from 0 to 110 kilometres per hour (68 mph) in three seconds, more quickly than most supercars.

The word "cheetah" is derived from the Sanskrit word chitrakāyaḥ, meaning "variegated body", via the Hindi

Description

The cheetah has a slender, long-legged body with blunt semi-retractable claws. Its chest is deep and its waist is narrow. The coarse, short fur of the cheetah is tan with round black spots measuring from 2 centimetres (0.79 in) to 3 centimetres (1.2 in) across, affording it some camouflage while hunting. There are no spots on its white underside, but the tail has spots, which merge to form four to six dark rings at the end. The tail usually ends in a bushy white tuft. The cheetah has a small head with high-set eyes. Black "tear marks" run from the corner of its eyes down the sides of the nose to its mouth to keep sunlight out of its eyes and to aid in hunting and seeing long distances.

The adult animal weighs from 40 kilograms (88 lb) to 65 kilograms (140 lb). Its total body length is from 115 centimetres (45 in) to 135 centimetres (53 in), while the tail can measure up to 84 centimetres (33 in) in length. Males tend to be slightly larger than females and have slightly bigger heads, but there is not a great variation in cheetah sizes and it is difficult to tell males and females apart by appearance alone. Compared to a similarly-sized leopard, the cheetah is generally shorter-bodied, but is longer tailed and taller (it averages about 90 centimetres (35 in) tall) and so it appears more streamlined.

Some cheetahs also have a rare fur pattern mutation: cheetahs with larger, blotchy, merged spots are known as 'king cheetahs'. It was once thought to be a separate subspecies, but it is merely a mutation of the African cheetah. The 'king cheetah' has only been seen in the wild a handful of times, but it has been bred in captivity.

The cheetah's paws have semi-retractable claws (known only in three other cat species - the Fishing Cat, the Flat-headed Cat and the Iriomote Cat) offering the cat extra grip in its high-speed pursuits. The ligament structure of the cheetah's claws is the same as those of other cats; it simply lacks the sheath of skin and fur present in other varieties, and therefore the claws are always visible, with the exception of the dewclaw. The dewclaw itself is much shorter and straighter than other cats.

Adaptations that enable the cheetah to run as fast as it does include large nostrils that allow for increased oxygen intake, and an enlarged heart and lungs that work together to circulate oxygen efficiently. During a typical chase its respiratory rate increases from 60 to 150 breaths per minute. While running, in addition to having good traction due to its semi-retractable claws, the cheetah uses its tail as a rudder-like means of steering to allow it to make sharp turns, necessary to outflank prey who often make such turns to escape.

Unlike "true" big cats, the cheetah can purr as it inhales, but cannot roar. By contrast, the big cats can roar but cannot purr, except while exhaling. However, the cheetah is still considered by some to be the smallest of the big cats. While it is often mistaken for the leopard, the cheetah does have distinguishing features, such as the aforementioned long "tear-streak" lines that run from the corners of its eyes to its mouth. The body frame of the cheetah is also very different from that of the leopard, most notably so in its thinner and longer tail, and unlike the leopard, its spots are not arranged into rosettes.

The cheetah is a vulnerable species. Out of all the big cats, it is the least able to adapt to new environments. It has always proved difficult to breed in captivity, although recently a few zoos have been successful. Once widely hunted for its fur, the cheetah now suffers more from the loss of both habitat and prey.

The cheetah was formerly considered to be particularly primitive among the cats and to have evolved approximately 18 million years ago. New research, however puts the last common ancestor of all 40 existing species of feline more recently, at 11 million years. The same research indicates that the cheetah, while highly derived morphologically, is not a particularly ancient lineage, having separated from its closest living relatives (the cougar Puma concolor and the jaguarundi Puma yaguarondi) around 5 million years ago.

Subspecies

For a short time it was thought that there were six subspecies of cheetah, but Acinonyx rex - the king cheetah (see below) - was abandoned after it was discovered the variation was only a recessive gene. The subspecies Acinonyx jubatus guttatus - the woolly cheetah - may also have been a variation due to a recessive gene. There are six subspecies recognized:

• Asiatic Cheetah (Acinonyx jubatus venaticus): northern Africa (Algeria, Djibouti, Egypt, Mali, Mauritania, Morocco, Niger, Tunisia and Western Sahara) and Asia (Afghanistan, India, Iran, Iraq, Israel, Jordan, Oman, Pakistan, Saudi Arabia, Syria, Russia and the Commonwealth of Independent States)
• Northwest African Cheetah (Acinonyx jubatus hecki): western Africa (Benin, Burkina Faso, Ghana, Mali, Mauritania, Niger, and Senegal)
• Acinonyx jubatus raineyii: eastern Africa (Kenya, Somalia, Tanzania, and Uganda)
• Acinonyx jubatus jubatus: southern Africa (Angola, Botswana, Democratic Republic of Congo, Mozambique, Malawi, South Africa, Tanzania, Zambia, Zimbabwe and Namibia)
• Acinonyx jubatus soemmeringii: central Africa (Cameroon, Chad, Central African Republic, Ethiopia, Nigeria, Niger, and Sudan)
• Acinonyx jubatus velox

Lion

The lion (Panthera leo) is a member of the family Felidae and one of four "big cats" in the genusPanthera. Reaching 272 kg (600 lb), it is the second-largest cat after the tiger. They currently exist in the wild in sub-Saharan Africa and in Asia with a critically endangered remnant population in northwest India, having disappeared from North Africa, the Middle East and western Asia in historic times. Until the late Pleistocene (about 10,000 years ago), the lion was the most widespread large land mammal beside man. They were found in most of Africa, much of Eurasia from western Europe to India and the Bering land bridge and in the Americas from Yukon to Peru.

Lions live for approximately 10–14 years in the wild, while in captivity they can live over 20 years. They typically inhabit savanna and grassland, although they may take to bush and forest. Lions are unusually social compared to other cats. A lion pride consists of related females and offspring and a small number of dominant males. Groups of female lions typically hunt together, preying mostly on large ungulates. The lion is an apex and keystone predator, though will resort to scavenging if the opportunity arises. While lions, in general, do not selectively hunt humans, some have been known to become man-eaters and seek human prey.

The lion is a vulnerable species, having seen a possibly irreversible population decline of 30 to 50% over the past two decades in its African range; populations are untenable outside designated reserves and national parks. Although the cause of the decline is not well-understood, habitat loss and conflicts with humans are currently the greatest causes of concern. Lions have been kept in menageries since Roman times and have been a key species sought after and exhibited in zoosAsiatic subspecies. the world over since the late 18th century. Zoos are cooperating worldwide in breeding programs for the endangered

The male lion is highly distinctive and is easily recognized by its mane. The lion, particularly the face of the male, is one of the most widely recognized animal symbols in human culture. Depictions have existed from the Upper Paleolithic period, with carvings and paintings from the Lascaux and Chauvet Caves, through virtually all ancient and medieval cultures where they historically occurred. It has been extensively depicted in literature, in sculptures, in paintings, on national flags, and in contemporary films and literature.

Subspecies

Southwest African lion (Panthera leo bleyenberghi)

Traditionally 12 recent subspecies of lion were recognized, the largest of which has been recognised as the Barbary Lion. The major differences between these subspecies are location, mane appearance, size and distribution. Because these characteristics are very insignificant and show a high individual variability, most of these forms were debatable and probably invalid; additionally, they were often based upon zoo material of unknown origin that may have had "striking, but abnormal" morphological characteristics.Today only eight subspecies are usually accepted, but one of these, the Cape lion formerly described as Panthera leo melanochaita is probably invalid. Even the remaining seven subspecies might be too much; mitochondrial variation in recent African lions is modest, which suggests that all sub-Saharan lions could be considered a single subspecies, possibly divided in two main clades: one to the west of the Great Rift Valley and the other to the east. Lions from Tsavo in Eastern Kenya are much closer genetically to lions in Transvaal (South Africa), than to those in the Aberdare Range in Western Kenya.

Recent

Eight recent subspecies are recognized today:

• P. l. persica, known as the Asiatic- or South Asian, Persian or Indian lion, was once widespread from Turkey, across the Middle East, to Pakistan, India and even Bangladesh. However, large prides and daylight activity made it easier to poach than tigers or leopards; now around 300 exist in and near the Gir Forest of India.
• P. l. leo, known as the Barbary lion, is extinct in the wild due to excessive hunting, although captive individuals may still exist. This was the largest of the lion subspecies, at 3–3.5m approx., and weighing over 150 kilograms and more. They ranged from Morocco to Egypt. The last wild Barbary lion was killed in Morocco in 1922.
• P. l. senegalensis, known as the West African lion, is found in Western Africa, from Senegal to Nigeria.
• P. l. azandica, known as the North East Congo lion, is found in the Northeastern parts of the Congo.
• P. l. nubica, known as the East African- or Massai lion, is found in East Africa, from Ethiopia and Kenya to Tanzania and Mozambique.
• P. l. bleyenberghi, known as the Southwest African- or Katanga lion. It is found in southwestern Africa, Zimbabwe, Angola, Katanga (Zaire).
• P. l. krugeri, known as the Southeast African- or Transvaal lion, is found in the Transvaal region of South eastern Africa, including Kruger National Park.
• P. l. melanochaita, known as the Cape lion, became extinct in the wild around 1860. Results of mitochondrial DNA research do not support the status as a distinct subspecies. It seems probable that the Cape lion was only the southernmost population of the extant southern African lion.

Tiger

The tiger (Panthera tigris) is a mammal of the Felidae family, the largest of four "big cats" in the Panthera genus.^[3] Native to much of eastern and southern Asia, the tiger is an apex predator and an obligate carnivore. Reaching up to 4 metres (13 feet) in total length and weighing up to 300 kg (660 pounds), tigers are comparable in size to the biggest extinct felids.^[4][5] Aside from their great bulk and power, their most recognizable feature is the pattern of dark vertical stripes that overlays near-white to reddish-orange fur, with lighter underparts.

Highly adaptable, tigers range from the Siberian taiga to open grasslands to tropical mangroveextinct and the remaining are classified as endangered, some critically so. The primary direct causes are habitat loss and fragmentationhunting. Their historical range, which once reached from Mesopotamia and the CaucasusSouth and East Asia, has been radically reduced. While all surviving species are under formal protection, poaching, habitat destruction and inbreeding depression continue to be threats. swamps. They are territorial and generally solitary animals, often requiring large contiguous areas of habitat that support their prey demands. This, coupled with the fact that they are endemic to some of the more densely populated places on earth, has caused significant conflicts with humans. Of the nine subspecies of modern tiger, three are and through most of

Nonetheless, tigers are among most recognizable and popular of the world's charismatic megafauna. They have featured prominently in ancient mythologies and folklore, and continue to be depicted in modern films and literature. Tigers appear on many flags, coats of arms and as mascots for sporting teams and serve as the national animal of several Asian nations.

Subspecies

There are nine recent subspecies of tiger, three of which are extinct, one of which is almost certain to become extinct in the near future, and five of which still occur. Their historical range (severely diminished today) ran through Russia, Siberia, Iran, Afghanistan, India, China and south-east Asia, including the Indonesian islands. The surviving subspecies in descending order of wild population are:

Bengal tiger : The Bengal tiger or the Royal Bengal tiger (Panthera tigris tigris) is found in parts of India, Bangladesh, Nepal, Bhutan and Burma. It lives in varied habitats: grasslands, subtropical and tropical rainforests, scrub forests, wet and dry deciduous forests and mangroves. Males in the wild usually weigh 205 to 227 kg (450–500 lb), while the average female will weigh about 141 kg.However, the northern Indian and the Nepalese Bengal tigers are supposed to be somewhat bulkier than those found in the south of the Indian Subcontinent, with males averaging around 520 lbs (236 kg). Population estimates range from 2,000 to 4,500. Since 1972, there has been a massive wildlife conservation project known as Project TigerSariska) has lost its entire tiger population to poaching. underway to protect the Bengal tiger. The project is considered as one of the most successful wildlife conservation programs, though at least one Tiger Reserve (

Indochinese Tiger : The Indochinese tiger (Panthera tigris corbetti), also called Corbett'sCambodia, China, Laos, Burma, Thailand, and Vietnam. These tigers are smaller and darker than Bengal tigers: Males weigh from 150–190 kg (330–420 lb) while females are smaller at 110–140 kg (242–308 lb). Their preferred habitat is forests in mountainous or hilly regions. Estimates of the Indonese tiger population vary between 1,200 to 1,800, with only several hundred left in the wild. The largest current population is in Malaysia, where illegal poaching is strictly controlled, but all existing populations are at extreme risk from habitat fragmentation and inbreeding. In Vietnam, almost three-quarters of the tigers killed provide stock for Chinese pharmacies. tiger, is found in

The Malayan tiger (Panthera tigris malayensis), exclusively found in the southern (Malaysian) part of the Malay Peninsula, was not considered a subspecies in its own right until 2004. The new classification came about after a study by Luo et al. from the Laboratory of Genomic Diversity Study, part of the National Cancer Institute of the United States. Recent counts showed there are 600–800 tigers in the wild, making it the third largest tiger population behind the Bengal tiger and the Indochinese tiger. The Malayan tiger is a national icon in Malaysia, appearing on its coat of arms and in logos of Malaysian institutions, such as Maybank.

Sumatran tiger : The Sumatran tiger (Panthera tigris sumatrae) is found only on the Indonesian island of Sumatra, and is critically endangered. It is the smallest of all living tiger subspecies, with adult males weighing between 100–130 kg (220–286 lb) and females 70–90 kg (154–198 lb). Their small size is an adaptation to the thick, dense forests of the Sumatra island where they reside, as well as the smaller-sized prey. The wild population is estimated at between 400 and 500, seen chiefly in the island's national parks. Recent genetic testing has revealed the presence of unique genetic markers, indicating that it may develop into a separate species, if it does not go extinct. This has led to suggestions that Sumatran tigers should have greater priority for conservation than any other subspecies. While Habitat destruction is the main threat to the existing tiger population (logging continues even in the supposedly protected national parks), 66 tigers were recorded as being shot and killed between 1998 and 2000, or nearly 20% of the total population.

Siberian tiger : The Siberian Tiger (Panthera tigris altaica), also known as the Amur, Manchurian or North China tiger, is confined to the Amur-Ussuri region of Primorsky and Khabarovsky Krai in far eastern Siberia, where it is now protected. Considered the largest subspecies, with an average weight of around 227 kg (500 lb) for males.^[18] The Amur tiger is also noted for its thick coat, distinguished by a paler golden hue and a fewer stripes. A six-month old Siberian tiger can be as big as a fully grown leopard. The last two censuses (1996 and 2005) found 450–500 Amur tigers within their single and more or less continuous range making it one of the largest undivided tiger populations in the world.

South China tiger : The South China tiger (Panthera tigris amoyensis), also known as the Amoy or Xiamen tiger, is the most critically endangered subspecies of tiger and is listed as one of the 10 most endangered species in the world. will almost certainly become extinct. It is one of the smaller tiger subspecies. The length of the South China tiger ranges from 2.2–2.6 m (87–104 in) for both males and females. Males weigh between 127 and 177 kg (280–390 lb) while females weigh between 100 and 118 kg (220–260 lb). From 1983 to 2007, no South China tigers were sighted. In 2007 a farmer spotted a tiger and handed in photographs to the authorities as proof. In 1977, the Chinese government passed a law banning the killing of wild tigers, but this may have been too late to save the subspecies. There are currently 59 known captive South China tigers, all within China, but these are known to be descended from only six animals. Thus, the genetic diversity required to maintain the subspecies may no longer exist. Currently, there are breeding efforts to reintroduce these tigers to the wild by 2008.

A hunted down Balinese Tiger.

• The Balinese tiger (Panthera tigris balica) has always been limited to the island of Bali. These tigers were hunted to extinction—the last Balinese tiger is thought to have been killed at Sumbar Kima, West Bali on 27 September 1937; this was an adult female. No Balinese tiger was ever held in captivity. The tiger still plays an important role in Balinese Hindu religion.

• The Javan tiger (Panthera tigris sondaica) was limited to the Indonesian island of Java. It now seems likely that this subspecies became extinct in the 1980s, as a result of hunting and habitat destruction, but the extinction of this subspecies was extremely probable from the 1950s onwards (when it is thought that fewer than 25 tigers remained in the wild). The last specimen was sighted in 1979, but there was a re-ignition of reported sightings during the 1990s.^[22][23]

• The Caspian tiger or Persian Tiger (Panthera tigris virgata) appears to have become extinct in the late 1950s, with the last reliable sighting in 1968, though it is thought that such a tiger was last shot dead in the south-eastern-most part of Turkey in 1970. Historically it ranged through Afghanistan, Iran, Iraq, Pakistan, the former Soviet Union, and Turkey.^[24] The Caspian tiger was a large subspecies and reached nearly the dimensions of the Bengal Tiger. The heaviest confirmed weight of a male was 240 kg. The ground colour was comparable to that of the Indian subspecies, but differed especially in the tight, narrow striping pattern. The stripes were rather dark grey or brown than black. Especially during the winter, the fur was relatively long. The Caspian tiger was one of two subspecies of tiger (along with the Bengal) that was used by the Romans to battle gladiators and other animals, including the Barbary Lion. The Romans traveled far to capture exotic beasts for the arena. There are still occasional reported sightings of the Caspian Tiger in the wild.

A liger is the offspring of a male lion and female tiger.

Hybrids

Hybridization among the big cats, including the tiger, was first conceptualized in the 19th century when zoos were particularly interested in the pursuit of finding oddities to display for financial gain.

Lions have been known to breed with tigers (most often the Amur and Bengal subspecies) to create hybrids called ligers and tigons.The liger is a cross between a male lion and a tigress. Because the lion sire passes on a growth-promoting gene, but the corresponding growth-inhibiting gene from the female lion is absent, ligers grow far larger than either parent. They share physical and behavioural qualities of both parent species (spots and stripes on a sandy background). Male ligers are sterile, but female ligers are often fertile. Males have about a 50% chance of having a mane, but if they grow one their manes will be modest: around 50% of a pure lion mane. Ligers are typically between 10 to 12 feet in length, and can be between 800 and 1,000 pounds or more. The less common tigon is a cross between the lioness and the male tiger. Such hybrids were once commonly bred in zoos, but this is now discouraged due to the emphasis on conserving species and subspecies. Hybrids are still bred in private menageries and in zoos in China.
