According to National Geographic, Siberian tigers are carnivores that eat other animals. Wild Siberian tigers mostly live in forests located in East Russia, and they hunt animals that are native to this area. Most Siberian tigers eat wild boar and elk, and they also feed on brown and black bears.
Siberian tigers often hunt at night by stalking and ambushing prey. Siberian tigers have stripes that camouflage them to help them blend into their environment while stalking prey. Generally, the tiger ambushes its prey and kills it almost instantly. Because most of its prey are large in size, a Siberian tiger can eat up to 60 pounds of flesh in one night of hunting.
Siberian tigers live and hunt alone. They are quite territorial and mark their territory to keep other tigers away. When a female tiger is searching for a mate, she also uses this scent-marking technique. Although tigers venture into each other's territory to mate, the male does not remain in a female's territory after mating. Thus, tiger cubs are raised exclusively by females.
Siberian tigers are an endangered species, although their numbers are beginning to stabilize. Siberian tigers were nearly hunted to extinction by trophy seekers. To prevent extinction, scientists are considering cross breeding Siberian tigers with another species of tiger, notes Wikipedia.
