The odd-toed ungulates or Perissodactyla are large to very large browsing and grazing mammals with relatively simple stomachs and a large middle toe. The members of the order fall into two groups: horses, which have only one toe and tend toward being fast runners with long-legs, and the sub-order Ceratomorpha, which contains two families of slower-moving, thick-set animals with several functional toes: the tapirs and the rhinoceroses.
In the early days of history of mammals they were numerous but now only 3 out of the original 12 families remain: 18 species in 6 genera.
