Wildlife society lists 12 animals most in danger of extinction
The eclectic list includes birds, mammals, fish, reptiles, amphibians and insects. Some are well known, such as the northern right whale and Sumatran rhino, while others are more obscure, including Abbot's booby, an ocean-going bird that only nests on Christmas Island.
Others on the list include the addax, the angel shark and the golden arrow poison frog.
