During a hunt, a tiger can jump up to 5 m high and 9–10 m in length. This allows it to effectively catch prey and overcome obstacles.
Like all members of the panther genus, the tiger, due to the structure of its larynx and vocal cords, is capable of producing a roar, although it mainly vocalizes only during the mating period.
Tigers cannot purr, unlike domestic cats, but produce a characteristic “chuff”.
A tiger’s stripes are unique like fingerprints and show even on the skin.
The tiger is the largest and heaviest of wild cats, but its subspecies vary greatly in size and body weight. Continental tiger subspecies are larger than those found on islands.
The tiger hunts alone, using two techniques: sneaking up on prey and waiting in ambush. The first technique is more commonly used in winter, the second in summer.
The Indian tiger is the largest among the continental tiger subspecies. It can reach a length of up to 2.6–2.8 meters without the tail and weigh up to 300–320 kg.
Approaching its prey to the closest possible distance, the tiger catches it with several huge jumps — the most rapid way of movement.
The length of a tiger's canine teeth without the root is 8 cm. This helps in holding and killing large prey.
A female tiger may have a territory of about 20 km², while males usually have territories of 60–100 km².
A female tiger gives birth to 10–20 cubs in her lifetime, but about half of them die at a young age.
A tiger can eat up to 30 kg of meat in one night and then not hunt for several days.
White tigers are not a separate subspecies but the result of a pigment-gene mutation; the last wild white tiger was shot in 1958.
A tiger can pretend to bury its kill if it senses competitors.
Tiger urine smells like buttered popcorn — that is how it marks territory.
The tiger is the best swimmer among big cats and can cross rivers several kilometres wide.
The white spots on the backs of the ears act as “false eyes”, deterring pursuers or helping cubs follow their mother.
In captivity tigers have lived more than 20 years; in the wild they rarely exceed 15.

年齢

The species typically lives for 15 to 20 years, with a maximum recorded lifespan of 26 years and 4 months, and a theoretical lifespan ranging from 13 years and 2 months to 26 years and 4 months. Sexual maturity is reached between 3 and 5 years of age; the eyes open between 1 and 2 weeks. The young begin to walk between 2 weeks and 4 days and 4 weeks, while the "Embryo" stage sees the fetus develop inside the mother for approximately three and a half months. A cub is born blind, weighing around one kilogram, and lives with its mother who feeds it milk. The "Cub" stage continues as the young tiger grows, and the "Adult" stage, when the animal becomes fully formed, hunts independently, can reproduce, and lasts from 4 to 20 years.

表現型

The young tiger has soft fur with stripes, which helps it to hide. Adult tigers possess long, sharp fangs that allow them to quickly kill prey by biting in the neck, and have sharp retractable claws on their paws, aiding in capturing prey and climbing trees. The species' fur is dense and orange in color with black stripes; each tiger’s stripe pattern is unique and helps it to camouflage in the forest. It also has long, sensitive whiskers that assist in navigation in darkness and precise distance determination.

生理学

The species exhibits a body height ranging from 22.9 centimeters to 1.2 meters, and a body length from 2.4 to 3.3 meters; mass varies from 86.94 to 110.59 kilograms. The young, referred to as cubs, have a body mass between 0.8 and 50 kilograms, and a body length from 50 centimeters to 1.6 meters. Adult individuals possess a body mass ranging from 180 kilograms to 0.3 metric tons, with a body length from 2.7 to 3.3 meters.

生息地

The species 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, tropical savannas with heat, uneven rainfall, abundant grasses, and trees, taiga forests featuring cold winters and coniferous trees such as spruce and pine, and temperate mixed forests with warm summers and many oak, birch, and maple trees; the species lives on land and in forest landscapes, at elevations up to 3 kilometers; the climate varies, with little precipitation in winter and more in summer, or with heat and heavy summer rains and little winter precipitation, or constant heat and humidity with nearly daily rain, or consistent heat throughout the year with frequent rainfall but occasional dry periods.

隠れ家

The tiger inhabits forests near water sources and utilizes dens for reproduction, rest, and protection from the sun.

地理

The species is found within the Indomalaya and Palearctic biogeographical realms, inhabiting several distinct ecosystems. Tigers occupy lowland moist deciduous forests of the Chao Phraya basin, as well as the moist deciduous forests of the northwestern Ghats. The species also lives in mountainous rainforests of the southwestern Ghats, the western Java rainforests, and the peat swamp forests of Tonle Sap-Mekong.

餌

The tiger is a predator that hunts large ungulates, including deer, wild boars, and buffaloes; the species employs an ambush hunting strategy to capture its prey, using a powerful bite to kill. The diet consists of deer, wild boars, buffaloes, antelopes, and other large mammals, and the hunting strategy involves active pursuit, ambush, and occasionally group hunting. Daily food requirements range from 5 kilograms to 9 kilograms, with cubs consuming milk. The species preys upon various animals, such as cattle, red deer, porcupines, manul cats, Asian buffaloes, deer, wild boars, elk, and Asian roe deer. In some cultures, the animal is consumed, but it is not considered halal or kosher.

繁殖

The species reproduces sexually with homogamy, always involving fertilization and no alternation of generations; gestation lasts 3 months and 2 weeks, and the female gives birth to live young on land without hatching from eggs or larvae. A litter has 2 to 4 cubs, and the male does not participate in raising them. The mother diligently cares for the young and teaches them how to hunt. The nest is located in an underground burrow, and only the mother exhibits parental care. The young develop within a ground nest, which may contain eggs or offspring. Tigresses reach maturity from 3 to 5 years of age and reproduce at intervals of 1 to 3 years. The species inhabits and develops on land outside of bodies of water.
