The order Perissodactyla includes the odd-toed ungulates (hoofed mammals) - rhinoceroses, tapirs, horses, asses and zebras.
If there’s no further information below, you might want to explore the groups this order belongs to or check out its children. Otherwise, you can try Google or check back again in a few weeks; GeoZoo is under constant development.

Distribution
These are not precise range maps. This series of maps merely indicate the continent(s) and ecozone(s) various groups of animals are native to.Perissodactyls are native to all continents but Australia and Antarctica. They are least diverse in the New World, where a few tapir species inhabit the tropics. This is ironic, since equids (horses and relatives) evolved in North America. Rhinoceroses were once very diverse in North America as well, though they apparently evolved in Eurasia.
During the Ice Age, the woolly rhinoceros roamed the northern tundra. Today, the northernmost odd-toed ungulate is the horse, which roamed across the grasslands and temperate forests of Eurasia in historic times.
Today, rhinoceroses are paleotropical, restricted to tropical Africa and Asia. Tapirs are restricted to tropical America, except for the Malayan tapir. Equids - horses, zebras and asses - range across Africa and temperate Eurasia.
Habitat
Tapirs and Asian rhinoceroses are adapted to tropical rainforests. Equids and African rhinoceroses are more closely associated with grasslands, with some equids living in arid deserts.
Habitat Niche
All odd-toed ungulates are fully terrestrial. No species are arboreal, semi-aquatic, etc.
