年齢
The Bengal tiger’s typical lifespan ranges from 19 years and 9 months to 32 years and 11 months, although the maximum recorded lifespan is 26 years; the species reaches sexual maturity between 3 and 5 years of age. The cub's eyes open between 1 and 2 weeks of age, and it begins to walk between 2 weeks and 4 days and 4 weeks. During the embryo stage, the developing fetus receives nourishment from the mother and does not eat independently. Following this, the young tiger lives with its mother, initially blind and consuming only milk, then progressing to meat and learning to hunt. The adult stage lasts from 4 to 20 years, during which the tiger lives alone and obtains food by itself; males are larger than females.

The young have sharp but small milk teeth that emerge after several weeks. Adult Bengal tigers possess long canines for quickly killing prey, and sharp, retractable claws to help catch and hold their food. The species' fur is orange with black stripes, and each individual tiger has a unique pattern.
生理学
The Bengal tiger’s body height ranges from 22.9 centimeters to 1.2 meters, and its body length varies from 2.3 to 3.1 meters; the species' mass is between 176.72 and 196.35 kilograms. During the embryonic stage, the developing young have a body mass of from 1 gram to 1 kilogram and a body length of from 10 to 30 centimeters. In the cub stage, the young’s body mass ranges from 0.8 to 80 kilograms, with a body length of from 50 centimeters to 1.6 meters. An adult individual’s body mass varies from 180 kilograms to 0.26 metric tons and its body length is between 2.7 and 3.1 meters.
生息地
The Bengal tiger inhabits tropical dry forests characterized by heat and a dry season with deciduous trees, tropical moist forests that are consistently hot and humid with large trees and vines, and tropical savannas featuring heat, uneven rainfall, and abundant grasses and trees; the species occupies terrestrial landscapes and forested areas. The elevation of its habitat reaches up to 2 kilometers. The climate varies, with summers experiencing almost no rain and winters having more precipitation, or with little winter rainfall and heavier summer rains, or with hot temperatures and minimal winter rainfall alongside summer rains, or with hot temperatures and heavy summer rains and minimal winter rainfall, or with consistently hot temperatures, frequent rains, and occasional dry periods.
隠れ家
The Bengal tiger resides in forests or thickets, utilizing dens as shelters for multiple purposes. These dens serve for reproduction, rest, and protection from the sun.
地理
The Bengal tiger occupies the Indomalaya biogeographical realm and is found in several ecosystems including dry deciduous forests of the Central Deccan Plateau, dry deciduous forests of Northern Deccan, rain forests of West Java, and semi-evergreen forests of Odisha.
餌
Bengal tigers are carnivores; the young initially drink their mother's milk and later consume meat from animals caught by the female. As adults, Bengal tigers hunt independently, employing ambush tactics and active hunting strategies, including group hunts. Their diet consists of deer, wild boars, small mammals, and large mammals, as well as caimans, pheasants, iguanas, galagos, and antelopes. The species obtains food through ambush and active hunting. A Bengal tiger’s daily food requirement ranges from 3 kilograms to 7 kilograms. Some cultures consume this animal, but it is not considered halal or kosher.
繁殖
The Bengal tiger reproduces through live birth, with gestation lasting 3 months and 2 weeks, and the female gives birth to a litter of 2 to 4 cubs; the young remain with their mother for 2 years. A litter has 2 to 4 cubs, and the father does not participate in raising them. The species inhabits and develops on land, outside of bodies of water, with nests built on the ground or close to it, sometimes hidden within an underground burrow. Only the mother displays parental care, sheltering the nest in an underground burrow. Reproduction involves homogamy, always resulting in fertilization without generational changes. The interval between breeding periods is 2 to 3 years. Sexual maturity occurs from 3 to 5 years.
