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.
Pygmy owl deposits in Poland (Mlíkovský 2002). Pygmy owl Pygmy owls are members of the genus Glaucidium. They belong to the typical owl family, Strigidae. The genus consists of about 26 to 35 species distributed worldwide. The exact number of species is somewhat disputed. These are mostly small owls, and some of the species are called "owlets". Most pygmy owl species are nocturnal and hunt mainly large insects and other small prey. "Glaucidium" forms a paraphyletic group with "Surnia". The supposed prehistoric species ""Glaucidium" dickinsoni" is now recognized as a burrowing owl, probably a paleosubspecies "providentiae". Bones of an indeterminate "Glaucidium" have
