Endangered pygmy hippo moves to London Zoo

STORY: The pygmy hippopotamus, from the forests of West Africa, is on a list of threatened species maintained by the International Union for Conservation of Nature.

There were roughly 2,500 left in the world the zoo said.

The pygmy is less aquatic and smaller than its non-pygmy hippo relatives, having a rounder and narrower head and a median life expectancy of 27 years.
