The name comes from the ancient Greek for "river horse" (). After the elephant and rhinoceros, the common hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the Hippopotamidae are cetaceans (whales, dolphins, porpoises, etc.) from which they diverged
Cloud-forest pygmy owl prone to natural fragmentation. Thus, like other species that are tied to cloud forest, it is known only from a very small range. It is found in low densities in the canopy and middle stratum of forest. Nevertheless, it can descend into the understory for feeding. In common with other species of pygmy owls, this species is quite diurnal, and consumes both invertebrates and small vertebrates. Nevertheless, owing to its small size and retiring habits -generally being perched in dense evergreen trees- it is not often noticed. The cloud-forest pygmy owl breeds principally between February and June. This fact allows
