LIKE Asian Bengal tigers, Siberian tigers have an estimated life expectancy of about 18 to 20 years in the natural habitat. This is the maximum life span of amur tigers. On an average, they live up to 15 years provided the food is abundant. The captive tigers however can live as long as 25 years. Bears also have the same life expectancy as tigers. Let’s see what factors largely determine the overall lifespan of a Siberian tiger.
Siberian Tiger Lifespan – How Long Do Siberian Tigers Live in the Wild?
Although wild Siberian tigers live up to 18 years, most individuals die around ten years age primarily due to the scarcity of food. The food intake is directly related to the overall life expectancy of Amur tigers. The greater is the food, the longer is the lifespan. One reason why captive specimens live almost 10 years more than the wild tigers is due to the abundance of food in reserves and zoos.
Sometimes, adult dominant males kill mother tiger and her cubs. However the high mortality rate in tigers is largely due to human hunting. They do not die of predation—tigers are just too big to be caught by the predators.
