Pygmy hippopotamuses are more terrestrial than Nile hippopotamuses but are good swimmers and have strong muscular valves that close their ears and nostrils when submerged. They also produce a whitish secretion that moistens and protects their skin. Unlike Nile hippopotamuses, their eyes are placed on the sides of the head and their nostrils are low on the face. The four digits on each foot are more widely spread and have little inter-digit webbing, giving pygmy hippopotamuses more secure footing on land.
