|† Megacerops & allies||An odd-toed ungulate is a mammal with hooves that feature an odd number of toes. The middle toe on each hoof is usually larger than its neighbours. Odd-toed ungulates are relatively large grazers and, unlike the ruminant even-toed ungulates (artiodactyls), they have relatively simple stomachs because they are hindgut fermenters, digesting plant cellulose in their intestines rather than in one or more stomachs. Odd-toed ungulates include the horse, tapirs, and rhinoceroses.
