Most live in [[Liberia]]. The pygmy hippo is [[nocturnal]]. It is one of only two living species in the [[Hippopotamidae]] family, the other being its much larger cousin the common [[hippopotamus]]. The pygmy hippopotamus, like its larger cousin, is semi-aquatic. Water keeps its skin moisturized and its body temperature cool. Behaviors such as mating and giving birth may happen in water or on land. The pygmy hippo is [[herbivorous]], feeding on [[fern]]s, [[grass]]es and [[fruit]]s in the forest. It is an [[endangered species]]. It is rare and has been since the 19th century. It is kept in some zoos. {{-}} {{biology-stub}} [[category:Mammals of Africa]] [[Category:Even-toed ungulates]]
