* * * There are nine subspecies, and there are great differences in size and morphology between them. The Northeast Tiger is the largest, the male is 3.7 meters long and weighs 423 kilograms. Sumatran tiger is the smallest surviving subspecies. The male tiger is 2.34m long and weighs136kg.
Tigers are typical mountain animals, which can survive well from tropical rain forests and evergreen broad-leaved forests in the south to deciduous broad-leaved forests and mixed coniferous and broad-leaved forests in the north. Tigers often act alone, and only in the breeding season do males and females live together. There are no fixed nests, and most of them wander in the mountains for food.
Can swim. Tigers are more active at dusk, more dormant during the day and rarely come out without being disturbed. Tigers have a wide range of activities, and their daily foraging activities can reach dozens of kilometers in the north; In the south, because there is more food, the movement distance is shorter.
The estrus mating period is generally from June 1 1 day to February of the following year. In estrus, the tiger's cry is particularly loud and can spread to 2 kilometers away. The gestation period is about 105 days, and each baby is 1-5, generally 2. The newborn tiger cub weighs about 1 kg and suckles for 5-6 months.
The tigress lives with her cubs for 2-3 years, during which time she has no estrus to mate, so under natural conditions, she can only breed once every 2-3 years. The female tiger is sexually mature at the age of 3, and the male tiger is later. The life span of a tiger is generally 20-25 years.
Due to the killing of human beings and the fragmentation of wild habitats, tigers have become rare and endangered species, and have been listed as the first-class protected animals in CITES Appendix of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, and the red list of endangered species in IUCN. According to the investigation in 20 16, the number of wild tigers in the world is 3890.
