Hippopotamus gorgops is a species of extinct hippo that lived in Africa from the late Pliocene through the Middle Pleistocene. They appear as dangerous animals in Ancestors.
The Hippopotamus (Hippo) is an "Irascible"(easily angered) animal they attack when a hominid gets close They are easily identified by their dark grey skin and large body, Hippos often travel in herds and are always backed up. H. gorgops are found in or near bodies of water in the Savanna, and will attack the player if provoked, either by getting close with a range similar to that of a predator or by being nearby when something is intimidated.
