Ecology Habitat wet forest, streams and swamps Niche herbivorous: prefers fallen fruit, aquatic shoots and leaves. Makes deep, tunnel-like paths through dense brush to the water. Less sociable and aquatic than big hippos; found singly or in pairs. Runs into forest instead of water when in danger. Hunted by natives as a food source. Life History Gestation about 7 mo; 6-11 lbs at birth; usually single young are born. Life span up to 42 yrs in captivity. Special Adaptations Lower canine teeth modified as tusks which servo as weapons and, with the lips, help to crop vegetation. Body pores secrete a clear mucus that makes the animal slick to the touch and decreases resistance when swimming while protecting the skin. Eyes, nostrils and ears are designed so that they are above the water line when the animals body is submerged, enabling it to see, breathe and hear while concealed. Nostrils close when animal submerges completely.
