Tiger

Tigers (Panthera tigris) are mammals of the Felidae family and one of four "big cats" in the Panthera genus. They are predatory carnivores and the largest of all cats, living or extinct. Template:Taxobox begin

Most tigers live in pies and cakes. (for which their camouflage is ideally suited). Among the big cats, only the tiger and jaguar are strong swimmers, and tigers are often found bathing in ponds, lakes and rivers. Tigers hunt alone and eat primarily medium-sized herbivores such as deer, wild pigs, and buffalo. However, they will also take larger or smaller prey on occasion. Humans are the tiger's only serious enemy and often kill tigers illegally for their fur or penises, which are used as aphrodisiacs in Chinese medicine. Poaching for fur and destruction of habitat have greatly reduced tiger populations and it has been placed on the endangered species list.

Physical characteristics

Although different subspecies of tiger have different characteristics, in general male tigers weigh between 150 and 310 kg (330 lb and 680 lb) and females between 100 and 160 kg (220 lb and 350 lb). The males are between 2.6 and 3.3 metres (8 ft 6 in and 10 ft 9 in) in length, and the females are between 2.3 and 2.75 metres (7 ft 6 in and 9 ft) in length. Of the more common subspecies, Corbetts Tigers are the smallest and Amur Tigers the largest.

The ground of the coat may be any colour from yellow to orange-red, with white areas on the chest, neck, and the inside of the legs. A common recessive variant is the white tiger, which may occur with the correct combination of parents; they are not albinos. Black or melanistic tigers have been reported, but no live specimen has ever been captured or photographed. Another variant, the golden tabby tiger (also called the "golden tiger" or "tabby tiger"), has a golden hue, much lighter than the colouration of normal tigers, and brown stripes. This form is very rare and only a handful of golden tabby tigers are known to exist, all in captivity. There are also old texts referring to 'blue'or 'Maltese' tigers, actually a silvery-grey tone, though no reliable evidence has been found.

The stripes of most tigers vary from brown or grey to pure black, although white tigers have far fewer apparent stripes. The form and density of stripes differs between subspecies, but most tigers have in excess of 100 stripes. The now extinct Javan Tiger may have had far more than this. The pattern of stripes is unique to each animal, and thus could potentially be used to identify individuals, much in the same way as fingerprints are used to identify people. This is not, however, a preferred method of identification, due to the difficulty of recording the stripe pattern of a wild tiger. It seems likely that the purpose of stripes is camouflage, serving to hide these animals from their prey (few large animals have colour vision as capable as that of humans, so the colour is not so great a problem as one might suppose). The stripe pattern is found on a tiger's skin and were you foolish enough to shave one, you would find that its distinctive camouflague pattern would be preserved.

Method of killing

Tigers overpower their prey from almost any angle, usually from ambush, and bite the neck, often breaking the prey's spinal column or windpipe, or severing the jugular vein or carotid artery, much as the domestic cat does to far-smaller prey.

Powerful swimmers, tigers are known to kill prey while swimming. Some tigers have even ambushed boats for the fishermen on board or their catch of fish.

Subspecies

There are eight separate subspecies of tiger, three of which are extinct and one of which is almost certain to become so in the near future. Their historical range (severely diminished today) ran through Russia, Siberia, Iran, Afghanistan, India, China and southeast Asia, including the Indonesian islands. These are the surviving subspecies, in descending order of wild population:

The Bengal Tiger (Panthera tigris tigris) is found through the forests and grasslands of Bangladesh, Bhutan, China, India and Nepal. It is the national animal of both India and Bangladesh. The estimated wild population of this subspecies is from 3,000 to 4,600, with most living in India and Bangladesh. These tigers are under severe pressure from both habitat reduction and from poaching; some recipes in Chinese medicine (in particular cures for impotence) require parts of tigers. Project Tiger, an Indian conservation project launched in 1972, has had limited success in protecting this subspecies.

Indochinese Tiger (Panthera tigris corbetti), also called Corbetts tiger, is found in Cambodia, China, Laos, Malaysia, Myanmar, Thailand, and Vietnam. Estimates of its population vary between 1,200 to 1,800, but it seems likely that the number is in the lower part of the range. 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. Also the tigers are seen by poor natives as a resource through which they can ease poverty.

The Sumatran Tiger (Panthera tigris sumatrae) is found only on the Indonesian island of Sumatra. The wild population is estimated at between 400 and 500 animals, occurring predominantly in the island’s five national parks. Recent genetic testing has revealed the presence of unique genetic markers, indicating that it may develop into a separate species, if it is not made extinct. This has led to suggestions that Sumatran Tigers should have greater priority for conservation than any other subspecies. Habitat destruction is the main threat to the existing tiger population (logging continues even in the supposedly protected national parks), but 66 tigers were recorded as being shot and killed between 1998 and 2000—nearly 20% of the total population.

The Siberian Tiger (Panthera tigris altaica), also known as the Amur, Manchurian or North China tiger, is confined almost totally to a very restricted part of eastern Russia where it is now protected. There are less than 400 of these tigers in the wild, and many populations are likely to no longer be genetically viable, subject to potentially catastrophic inbreeding. By far the largest subspecies, with males exceeding lengths of 12 feet and weights of 850 pounds, the Siberian Tiger is also noted for its thick coat, distinguished by a paler golden hue and a smaller number of stripes.

The South China Tiger (Panthera tigris amoyensis), also known as the Amoy or Xiamen tiger, is the most critically endangered subspecies of tiger, and will almost certainly become extinct. It seems likely that the last known wild South Chinese tiger was shot and killed in 1994, and no live tigers have been seen in their natural habitat for the last 20 years. In 1959, Mao Zedong declared the tiger to be a pest, and numbers quickly fell from about 4,000 to approximately 200 in 1976. In 1977 the Chinese government reversed the law, and banned the killing of wild tigers, but this appears to have been too late to save the subspecies. There are currently 59 known captive Chinese tigers, all within China, but these are known to be descended from only 6 animals. Thus, the genetic diversity required to maintain the subspecies no longer exists, making its eventual extinction very likely.

Recently Extinct

The Javan Tiger (Panthera tigris sondaica) was limited to the Indonesian island of Java. It now seems likely that this subspecies was made 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.

The Caspian Tiger or Persian Tiger (Panthera tigris virgata) appears to have become extinct in the late 1960s, with the last reliable sighting in 1968. Historically it ranged through Afghanistan, Iran, Iraq, Pakistan, the former Soviet Union and Turkey. It was said, such a tiger was last shot dead in the south-eastern-most Turkey in 1970.

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.

Maneaters

Of all the big cats, tigers have the greater predisposition towards turning into maneaters, i.e. specifically targetting humans as prey. There are many reasons why tigers that otherwise would attack humans only if threatened begin to prefer to eat humans. An aged, sick, or injured tiger may lose the agility and speed needed to catch swifter prey or a healthy tiger may simply find human beings a convenient target in heavily populated regions like those found in India, home to the deadly Bengal Tiger. It is also said that a tiger actually prefers human flesh to most other meat, although some forms, such as the Siberian tiger, have never been known to prey on humans. Whatever the reasons, tigers, especially in the swamps and mangrove forests of the Sunderbans, are amongst the deadliest predators in the world. Tigers often ambush humans from the water here and fear of them has kept the region largely free from human habitation.

Jim Corbett in his book "Maneaters of Kumaon" describes how he shot the man-eating tigers responsible for killing nearly 1500 people. The most notorious was the Champawat Tiger, which alone devoured 436 people, a record that stands to this day.

Tigers in literature and popular culture

Tyger! Tyger! Burning bright
In the forests of the night,
What immortal hand or eye
Could frame thy fearful symmetry?

William Blake, "The Tyger", Songs of Experience

The word tiger is borrowed from Greek tigris, itself borrowed from Persian ([1]). American English Tigress first recorded 1611. Tiger's-eye "yellowish-brown quartz" is recorded from 1891.

The tiger has certainly managed to appeal to man's imagination. Both Rudyard Kipling in The Jungle Books and William Blake in his Songs of Experience depict him as a ferocious, fearful animal. In The Jungle Books, the tiger Shere Khan is the biggest and most dangerous enemy of Mowgli, the uncrowned king of the jungle. Even in the Bill Watterson comic strip, Calvin and Hobbes, Hobbes the tiger sometimes escapes his role of cuddly animal. At the other end of the scale there is Tigger, the tiger from A. A. Milne's Winnie the Pooh stories, who is always happy and never induces fear. In the award winning A Tiger for Malgudi, a Yogi befriends a tiger. Tony the Tiger is renowned for his Frosted Flakes.

A stylized tiger was a mascot of the 1988 Summer Olympic Games of Seoul. Tigers have been used in advertising such commodities as gasoline and breakfast cereal in long-standing advertising campaigns.

Most recently, Yann Martel won the Man Booker Prize in 2002 with his novel Life of Pi about an Indian boy castaway on the Pacific Ocean with a Royal Bengal Tiger.

The talking feline companion of He-Man, Battlecat, is obviously modeled after a Tiger.
