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.

Pygmy salamander in light of the species having a wide distribution, a large population, and being unlikely to decline fast enough to be placed in a more threaten category. Threats to the pygmy salamander include deforestation of spruce-fir forest. Acid rain is also a threat at the high elevation that can destroy the spruce-fir trees in the pygmy salamander’s natural habitat.
