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.
Northern pygmy salamander Northern pygmy salamander The northern pygmy salamander (or northern pigmy (sic), "Desmognathus organi") is a terrestrial species of salamander in the family Plethodontidae and genus "Desmognathus". Along with the southern pygmy ("D. wrighti") and the seepage salamander ("D. aeneus"), these are some of the smallest salamander species in North America and can be found in higher elevations in the southern Appalachians. "Desmognathus organi" can be identified by its small size, averaging only 40–60 mm total length, and its distinct herringbone pattern on the dorsal side and copper colored eyelids, which are traits only shared with "D. wrighti". Dorsal coloration can
