Tigers can grow to 11 feet (3.3 meters) and 660 lb (300 kilograms).
Siberian tigers are the largest species of tigers.
They are also known as Amur, Manchurian, Ussurian, or Northeast China tigers.
Females are drastically smaller than males, reaching lengths of 8.5 feet rather than 11 feet, and 200-370 lb rather than 660 lb.
Their primary habitats are small regions in Southeast Russia, China, and North Korea.
Siberian tigers have a stable population, but are still endangered. This is an improvement from 1996, when they were classified as "critically endangered," according to the ICUN.
