Pygmy hippopotamus Pygmy hippopotamus The pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis") is a small hippopotamid which is native to the forests and swamps of West Africa, primarily in Liberia, with small populations in Sierra Leone, Guinea, and Ivory Coast. The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the family Hippopotamidae, the other being its much larger relative, the common hippopotamus ("Hippopotamus amphibius") or Nile hippopotamus. The pygmy hippopotamus displays many terrestrial adaptations, but like the hippo, it is semiaquatic and relies on water to keep its skin moist and its body temperature cool.
Lesser pygmy flying squirrel Lesser pygmy flying squirrel The lesser pygmy flying squirrel ("Petaurillus emiliae") is a species of rodent in the family Sciuridae. It is endemic to Malaysia. It is listed as Data Deficient because it is known only from the type specimen collected in 1901. Adequate surveys have not been done to look for this species, and so it cannot be considered Extinct. The lesser pygmy flying squirrel is arboreal and probably prefers forest. It is threatened by habitat conversion due to agriculture and logging. There are no conservation measures in place. Further studies are needed into the taxonomy, distribution, abundance, reproduction
