Your morning adorable: Three bumps -- er, Siberian tiger cubs -- on a log
Germany's Nuremberg Zoo welcomed Rangar, Khan and Domur, Siberian tiger cubs, back in August. Since Siberian tigers (also called Amur tigers) are endangered -- it's believed that only about 400 to 500 animals remain in the wild in eastern Russia and parts of China and North Korea -- these three healthy cubs have given the zoo great cause for celebration.
Siberian tigers are the largest of the tiger subspecies still in existence today. There were once eight subspecies, but three (the Caspian tiger, Javan tiger and Bali tiger) became extinct during the 20th century. The five remaining subspecies are all considered endangered.
