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

Juveniles are duller. The genus was defined by French naturalist René-Primevère Lesson in 1831. The name "Micropsitta" is derived from the Greek "mikros" meaning small and "psitta" for parrot. The pygmy parrots consist of six species and several subspecies: Genus: "Micropsitta" (pygmy parrots) Pygmy parrot Pygmy parrots are the smallest members of the parrot order. The six species of pygmy parrots are all in the genus Micropsitta, which
