Like the "even-toed" Artiodactyla, perissodactyls are unguligrades; that is, they walk on the terminal bones of the toes and have enlarged toenails forming hoofs.Unlike artiodactyls, perissodactyls either walk on three toes (like rhinos, tapirs, many extinct horses, and other extinct groups) or on a single toe (like recent horses). There are about 220 species in this order in 10 families. Artiodactyla is an order of even-toed mammals that walk on their toenails (unguis). Check out this video to find out the answer. Artiodactyla and Perissodactyla (Mammalia) from the Early-Middle Eocene Kuldana Formation of Kohat (Pakistan) @inproceedings{Thewissen1987ArtiodactylaAP, title={Artiodactyla and Perissodactyla (Mammalia) from the Early-Middle Eocene Kuldana Formation of Kohat (Pakistan)}, author={J.

Most of the species in this order live in open habitats like grasslands and plains, but some live in forested areas. During the Caenozoic the forestomach‐fermenting Artiodactyla were strongly radiating, which is in contrast to conditions in hindgut‐fermenting Artiodactyla (Suidae) and Perissodactyla (Equidae, Rhinocerotidae, Tapiridae). is that perissodactyl is any ungulate mammal with an odd number of toes and belonging to the perissodactyla, including the horses, zebra, and rhinoceros while artiodactyl is (zoology) any ungulate mammal with an even number of toes and belonging to the artiodactyla, including pigs, sheep, deer, cattle, and most grazing animals.
