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
Pygmy slow loris the Association of Zoos and Aquariums established a Species Survival Plan for the species, following a proposal by the Global Captive Action Plan for Primates to create a breeding program to maintain its genetic diversity. As of 2008, the captive population in North America had grown to 74 individuals, with most of them born at the San Diego Zoo; as of 2013, the species is the most common lorisid primate kept in North American zoos. About 175 pygmy lorises live in breeding facilities worldwide. Pygmy slow loris The pygmy slow loris ("Nycticebus pygmaeus") is a species of slow loris found
