The pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis) is a small hippopotamid native to the forests and swamps of West Africa, primarily in Liberia and small populations in Sierra Leone, Guinea and Ivory Coast. The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the Hippopotamidae family, the other being its much larger cousin the common hippopotamus.
