About the Pygmy Hippopotamus


Geographic Range:


Class: Mammalia 
Order: Cetartiodactyla 
Family: Hippopotamidae  
Genus: Choeropsis
Species: liberiensis

The pygmy hippo is a stout animal with a relatively small and rounded head and thick blackish skin. Like the larger Nile hippo, it excretes reddish droplets that soften and protect its skin. This creature is solitary and secretive in the wild. It's not vicious, but can be dangerous when disturbed. The pygmy hippo will attempt to intimidate potential enemies by opening its jaws and baring its canine teeth.
