A tapir is a large, herbivorous mammal, similar in shape to a pig, with a short, prehensile nose trunk. Tapirs inhabit jungle and forest regions of South America, Central America, and Southeast Asia. The five extant species of tapirs, all of the family Tapiridae and the genus Tapirus, are the Brazilian tapir, the Malayan tapir, Baird's tapir, the kabomani tapir and the mountain tapir. The four species that have been evaluated (all except the kabomani) are all classified on the IUCN Red List as Endangered or Vulnerable. The tapirs have a number of extinct relatives in the superfamily Tapiroidea. The closest extant relatives of the tapirs are the other odd-toed ungulates, which include horses, donkeys, zebras and rhinoceroses.
