Amur Leopard
The Amur leopard, a subspecies of leopard, is a solitary, nocturnal animal with a wild population of below 100 individuals mostly residing in the Amur River basin of eastern Russia with a few in neighbouring China. These leopards are particularly vulnerable to extinction given that they have the lowest level of genetic variation of any leopard subspecies. (http://bit.ly/2OIuJ3T)
