Amur tigers give birth to a litter of cubs (usually three or four) after a gestation period of about 3.5 months, according to Tigers.org. The mortality rate of young tiger cubs is "very high" – only about half survive to reach maturity, the website adds.
Tigers grow to be upwards of 396-660 pounds and 10 feet long, the World Wildlife Federation says.
The Amur tiger is considered endangered, with as many as 540 living in the wild, the federation notes. Their habitat is forested areas in eastern Russia and the China border, as well as North Korea.
