Overview

The tiger (Panthera tigris) is the largest living member of the cat family Felidae and one of the most recognisable wild animals on Earth. Tigers are solitary ambush hunters built for short, powerful bursts of speed across dense forest, tall grassland and mangrove habitats. The species is divided into several subspecies, of which the Bengal and Amur (Siberian) tiger are the most widely studied.

Conservation note: The tiger is currently classified as Endangered on the IUCN Red List (verify current status at iucnredlist.org before publication). Several subspecies are considered critically threatened, and historical range has contracted dramatically over the past century.

Habitat & Range

Tigers occupy a much wider range of habitats than their popular image suggests — from the snow-bound boreal forests of the Russian Far East (Amur tiger) to the tropical evergreen forests of South and Southeast Asia, the grasslands of central India, and the mangrove swamps of the Sundarbans on the India–Bangladesh border.

The unifying ecological requirement is dense cover for stalking, sufficient large prey, and access to water. Wild tigers no longer occur naturally in West or Central Asia, where they were historically present.

Diet

Tigers are obligate carnivores and apex predators. Primary prey includes large deer species such as sambar and chital, wild pigs, gaur, and other large ungulates depending on region. A tiger typically hunts alone, relying on stealth, cover, and a powerful final charge rather than a long pursuit.

A single tiger may consume large amounts of meat per kill and then go several days without feeding. They will also scavenge when the opportunity arises.

Behavior

Unlike lions, tigers are strongly solitary. Adults maintain individual territories marked by scent, scrapes, and visual signs. Territories of males typically overlap with those of several females. Direct social contact outside of mating and the raising of cubs is limited.

Tigers are strong swimmers, frequently entering water to cool down or to cross rivers and waterways — a behaviour particularly characteristic of populations in Sundarbans mangroves.

Human Interaction & Conservation

Tigers face severe pressures from habitat loss, prey depletion, retaliatory killing in response to livestock predation, and poaching driven by demand for body parts in illegal wildlife trade. National protected-area networks — for example India's Project Tiger reserves — and trans-boundary conservation efforts have stabilised some populations, but many remain fragmented and vulnerable.

Appearance & Recognition

The tiger is unmistakable among living mammals. Its base coat ranges from a pale yellow-orange in some populations to a richer rust-orange in others, marked with vertical black or dark-brown stripes that continue onto the limbs and tail. Stripe patterns are individually unique — comparable in that sense to a human fingerprint — and are sometimes used in identification studies of wild populations. The belly, inner limbs and inside of the muzzle are typically white or cream.

Tigers have a heavy, muscular build with a broad head, powerful forequarters, and proportionally long hind limbs adapted for the explosive forward leap that ends a stalk. Forepaws are large and broad; the retractable claws and dental arrangement are typical of large felids. Males are generally larger than females across subspecies, but reported size figures vary considerably by source and population — they should be treated as ranges rather than fixed values.

Similar Animals

Other large cats sharing parts of the tiger's range or ecological role include the leopard (Panthera pardus) and, in different ecosystems, the lion (P. leo). The jaguar (P. onca) occupies a comparable apex predator role in the Americas. The cheetah (Acinonyx jubatus) shares parts of the tiger's historical Asian range but is a fundamentally different — open-country, pursuit-hunting — cat.

Frequently Asked Questions — Tiger

Which is the largest tiger subspecies?
The Amur (Siberian) tiger is generally regarded as the largest, with the Bengal tiger close behind. Subspecific weight ranges overlap, and figures vary by source and study population. Reported maximums for very large males can exceed 250 kg, but most adults fall well below this.
Do tigers attack humans?
Tigers generally avoid humans. Documented human predation occurs in specific contexts — for example, in the Sundarbans, or where tigers are injured, aged, or have lost natural prey. Conflict risk increases where human settlements push into tiger habitat or where livestock is unsecured at night.
How fast can a tiger run?
Tigers are capable of fast short-distance bursts, estimated in the range of 50–65 km/h. They are not built for prolonged chases and rely on closing the distance through cover before launching a final sprint.
Are white tigers a separate species?
No. White tigers are not a subspecies. The white coat results from a recessive genetic variant, and almost all white tigers in captivity descend from a small number of related individuals, raising welfare and genetic-diversity concerns. They do not occur in any meaningful wild population today.
