Both snow white and golden tigers are homozygous for CORIN gene mutations. To preserve this recessive trait, only a few white individuals were used in captive breeding, which led to a high degree of inbreeding.  Demand for tiger parts for use in traditional Chinese medicine has also been cited as a major threat to tiger populations. The average prey weight in the two respective big cats in India was 37.6 kg (83 lb) against 91.5 kg (202 lb). The local maharaja started breeding tigers in the early 1950s and kept a white male tiger together with its normal-coloured daughter; they had white cubs.  A black tiger is a colour variant due to pseudo-melanism. Most man-eating tigers are old, missing teeth, and unable to capture their preferred prey.

Tiger sharks have very thick hides, once described by a scientist as six to 10 times the strength of an ox hide [source: Tennesen]. Females lactate for five to six months. The Lion is the next largest big cat after the Tiger. Weaker cubs get less food because of the aggressiveness of their stronger siblings as food is less frequently made available.  In Korean myth and culture, the tiger is regarded as a guardian that drives away evil spirits and a sacred creature that brings good luck – the symbol of courage and absolute power. Estimates vary, but Saffoe says an average adult male African lion and an average adult male Bengal tiger (the most common wild tiger subspecies) both weigh in the neighborhood of 400 to 420 pounds (180 to 190 kilograms).  The potential tiger range during the late Pleistocene and Holocene was predicted applying ecological niche modelling based on more than 500 tiger locality records combined with bioclimatic data. In May 2015, Amur tigers were photographed by camera traps in the Sikhote-Alin Bioshpere Reserve. They start to eat meat at the age of eight weeks.  In 2005, there were thought to be about 360 animals in Russia, though these exhibited little genetic diversity.  The tiger is one of only a few striped cat species; it is not known why spotted patterns and rosettes are the more common camouflage pattern among felids. Resident adults of either sex generally confine their movements to their home ranges, within which they satisfy their needs and those of their growing cubs.  In the Eastern Himalayas, tigers were documented in subalpine forest up to an elevation of 3,630 m (11,910 ft). , When not subject to human disturbance, the tiger is mainly diurnal.  A tiger's coat pattern is still visible when it is shaved. However, tigers cause more human deaths through direct attack than any other wild mammal. In either sex, the tail represents about 0.6 to 1.1 m (24 to 43 in) of the total length.  The WWF subsequently declared that the world's count of wild tigers had risen for the first time in a century.  , When hunting larger animals, tigers prefer to bite the throat and use their powerful forelimbs to hold onto the prey, often simultaneously wrestling it to the ground.  It also reflects the classification used by the Cat Classification Task Force in 2017: A study published in 2018 was based on 32 tiger specimens using the whole-genome sequencing approach for analysis. , The tiger's closest living relatives were previously thought to be the Panthera species lion, leopard and jaguar.  In 1929, the British taxonomist Reginald Innes Pocock subordinated the species under the genus Panthera using the scientific name Panthera tigris. for almost three years was feeding 3 year old Kimba Tiger. In order of size, the big cats are Tiger, Lion, Jaguar and Leopard. Although almost exclusively carnivorous, tigers will occasionally eat vegetation for dietary fibre such as fruit of the slow match tree. When tense, tigers will moan, a sound similar to a roar but more subdued and made when the mouth is partially or completely closed. A. Milne's Winnie-the-Pooh and Hobbes of the comic strip Calvin and Hobbes, both of whom are represented as simply stuffed animals come to life. Having evolved in the temperate and subtropical forests of eastern Asia, the tiger is less tolerant of heat than other large cats, which may explain why it is an adept swimmer that appears to enjoy bathing. Cubs weigh from 780 to 1,600 g (1.72 to 3.53 lb) each at birth, and are born with eyes closed.  Currently, it occurs in less than 6% of its historical range, as it has been extirpated from Southwest and Central Asia, large parts of Southeast and East Asia. In captivity their lifespan is about 20 to 25 years. Different types of tigers have various weights, with the heaviest being the Siberian tiger at an average of 400 to 675 lbs.  The seals of several Chola copper coins show the tiger, the Pandyan emblem fish and the Chera emblem bow, indicating that the Cholas had achieved political supremacy over the latter two dynasties.

They open their eyes when they are six to 14 days old.  With relatively abundant prey, tigers and leopards were seen to successfully coexist without competitive exclusion or interspecies dominance hierarchies that may be more common to the African savanna, where the leopard exists with the lion. They establish and maintain territories but have much wider home ranges within which they roam. In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group revised felid taxonomy and recognized the tiger populations in continental Asia as P. t. tigris, and those in the Sunda Islands as P. t. , Results of craniological analysis of 111 tiger skulls from Southeast Asian range countries indicate that Sumatran tiger skulls differ from Indochinese and Javan tiger skulls, whereas Bali tiger skulls are similar in size to Javan tiger skulls.

The Indo-Chinese (P. tigris corbetti), and Sumatran (P. tigris sumatrae) tigers are bright reddish tan, beautifully marked with dark, almost black, vertical stripes. This is not due to skin pigmentation, but to the stubble and hair follicles embedded in the skin, similar to human beards (colloquially five o'clock shadow), and is in common with other big cats. Gestation ranges from 93 to 114 days, with an average of 103 to 105 days. It is where adult tigers may also live solitary lives. A single maharaja or English hunter could claim to kill over a hundred tigers in their hunting career.  However, in a decade later, the Siberian tiger census was estimated from 480 to 540 individuals. , The tiger is essentially associated with forest habitats.  Stephen Mills described a social feeding event in Ranthambhore National Park: A dominant tigress they called Padmini killed a 250 kg (550 lb) male nilgai – a very large antelope. The book has sold over four million copies, and has been the basis of both fictional and documentary films. Northwestern China is thought to be the origin of the tiger lineage.  For example, the Champawat Tiger, a tigress found in Nepal and then India, had two broken canines. The Sumatran Tiger Project (STP) was initiated in June 1995 in and around the Way Kambas National Park in order to ensure the long-term viability of wild Sumatran tigers and to accumulate data on tiger life-history characteristics vital for the management of wild populations. , In Buddhism, the tiger is one of the Three Senseless Creatures, symbolising anger, with the monkey representing greed and the deer lovesickness.

Many Siberian tigers in zoos today are actually the result of crosses with Bengal tigers. Healthy large mammals are generally avoided, although there have been recorded instances of the tiger’s having attacked elephants and adult water buffalo. This altered pigmentation is caused by a mutant gene that is inherited as an autosomal recessive trait, which is determined by a white locus. The males can weigh up to 488 pounds with the females weighing about 308 pounds. If these are not sufficient, the conflicts may turn violent; tigers may kill competitors as leopards, dholes, striped hyenas, wolves, bears, pythons, and crocodiles on occasion.

They were smaller than mainland tiger fossils, possibly due to insular dwarfism. Nonetheless, confrontations do occur, sometimes resulting in injury and even death. Results of genetic analysis indicate that about 2.88 million years ago, the tiger and the snow leopard lineages diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar. Cattle are occasionally taken from human habitations, and some tigers can thrive on domestic livestock.

Males, however, migrate further than their female counterparts and set out at a younger age to mark out their own area. , In China, tigers became the target of large-scale 'anti-pest' campaigns in the early 1950s, where suitable habitats were fragmented following deforestation and resettlement of people to rural areas, who hunted tigers and prey species.  Though rarely observed, some tigers have been recorded to kill prey by swiping with their paws, which are powerful enough to smash the skulls of domestic cattle, and break the backs of sloth bears. It featured prominently in ancient mythology and folklore and continues to be depicted in modern films and literature, appearing on many flags, coats of arms and as mascots for sporting teams.

For the people who live in and around the forests of Korea, the tiger considered the symbol of the Mountain Spirit or King of mountain animals. Black tigers have been reported less frequently from the dense forests of Myanmar (Burma), Bangladesh, and eastern India. Historical records in Iran are known only from the southern coast of the Caspian Sea and adjacent Alborz Mountains. A special liking for porcupines, despite the danger of injury from their quills, is an exception.  The competitive exclusion of wolves by tigers has been used by Russian conservationists to convince hunters to tolerate the big cats. While the tiger, or Pantheri tigris, a large cat native to parts of Asia, India and Russia can weigh in at over 300 pounds and measure over 12 feet in length, they start off really tiny and completely helpless. Although predators typically avoid one another, if a prey item is under dispute or a serious competitor is encountered, displays of aggression are common. After consuming what they can of their prey, tigers hide animal carcasses from scavengers so they can return to them later. Inbreeding depression is the main reason for many health problems of captive white tigers, including strabismus, stillbirth, deformities and premature death. , Generally, males vary in total length from 250 to 390 cm (8.2 to 12.8 ft) and weigh between 90 and 300 kg (200 and 660 lb) with skull length ranging from 316 to 383 mm (12.4 to 15.1 in). , The tiger's full genome sequence was published in 2013. A more realistic version of the tiger entered the heraldic armory through the British Empire's expansion into Asia, and is referred to as the Bengal tiger to distinguish it from its older counterpart. , In 2015, morphological, ecological, and molecular traits of all putative tiger subspecies were analysed in a combined approach. , The less common tigon is a cross between a lioness and a male tiger.

The Udege and Nanai called it "Amba". The major obstacle in preserving the species is the enormous territory individual tigers require (up to 450 km2 needed by a single female and more for a single male).  Generation length of the tiger is about eight years. During this period the family was joined by two adult females and one adult male, all offspring from Padmini's previous litters, and by two unrelated tigers, one female the other unidentified. White Bengal tigers or tigers of mixed Bengal/Amur ancestry have pink noses, white-to-creme coloured fur and black, grey or chocolate-coloured stripes. In southern India the god Ayyappan was associated with a tiger.
