Aquatic Ungulate - With eyes, nostrils and ears located high on the head, hippos can see, hear and breathe while staying almost totally submerged. Hippos can stay completely underwater for five to six minutes. Their body weight distribution and webbed feet allow them to move easily in water. Hippos cannot sweat, so submerging in water or covering themselves with mud helps keep their bodies cool during the heat of the day.
Muck-spreading - Hippos practice “muck-spreading” which occurs when the tail is vigorously wagged during defecation. This action scatters feces in a wide range and may serve to mark territory or mark trails from the water to their grazing areas.
