Hippos live in sub-Saharan Africa. They live in areas with abundant water, as they spend most of their time submerged to keep their skin cool and moist. Considered amphibious animals, hippos spend up to 16 hours per day in the water, according to National Geographic.
Common hippos are recognisable by their barrel-shaped torsos, wide-opening mouths revealing large canine tusks, nearly hairless bodies, columnar legs and large size; adults average 1,500 kg and 1,300 kg for males and females respectively.
Despite its stocky shape and short legs, it is capable of running 30 km/h over short distances. Their gait is like a gallop although they don't lift all four feet off the ground at once.
