Grizzly Polar = Polar Bear + Brown Bear

Also known as Grolar Bear, this bear hybrid is a rare ursid hybrid that has occurred both in captivity and in the wild. In 2006, the occurrence of thishybrid in nature was confirmed by testing the DNA of a strange-looking bear that had been shot on Banks Island in the Canadian arctic. 

A number of polar bear hybrids are described as Ursid hybrids, a term that designates any hybrid of two species within the Ursidae family. Polar bear hybrids with Grizzly bears have been reported and shot, but DNA techniques were not available to verify the bears' ancestry.
