Pygmy hippopotamus the pygmy hippopotamus, are considered dwarf hippopotamuses, rather than pygmies. They are likely descended from a full-sized species of European hippopotamus, and reached their small size through the evolutionary process of insular dwarfism which is common on islands; the ancestors of pygmy hippopotami were also small and thus there was never a dwarfing process. There were also several species of pygmy hippo on the island of Madagascar (see Malagasy hippopotamus). Pygmy hippos share the same general form as a hippopotamus. They have a graviportal skeleton, with four stubby legs and four toes on each foot, supporting a portly frame. The
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
