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.
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.
