Spot the rare Amur leopard - the world’s most endangered big cat - hiding in this picture

The cat was snapped at the Land of the Leopard Nature Reserve in the Far East of Russia, a national park set up to save this species. 

The amazing picture was taken by senior state inspector of the reserve Andrey Troyanov.

There are only 86 adults and 21 adolescents known to be living in their natural habitat, and the future of the species as a wild - rather than zoo - animal depends on them.

While still highly endangered, two decades ago there were only 30 known adults after years of poaching during the Soviet era. 

There are less than 120 of these animals living in the wild. Pictures: Land of the Leopard Nature Reserve 

Around 100 years ago the cats populated all of the Korean peninsula and two provinces of China, as well as regions in eastern Russia.  

The Land of the Leopard Nature Reserve also protects endangered Amur tigers, the world’s largest big cat. 

Here, too, are populations of both brown and black bears.

But it is the leopard that is the most vulnerable. Still, if they hide as well as this one, then there are hopes for the survival of the species.
