perissodactyl

any member of the order Perissodactyla, a group of herbivorous mammals characterized by the possession of either one or three hoofed toes on each hindfoot. They include the horses, asses, and zebras, the tapirs, and the rhinoceroses. The name (Greek perissos, "odd," and daktylos, "finger") was introduced to separate the odd-toed ungulates from the even-toed ones (Artiodactyla), all of which had previously been classified as members of a single group
