Definition of Perissodactyla in English:
An order of mammals that comprises the odd-toed ungulates. Compare with Artiodactyla.
- ‘Odd-toed’ or ‘odd-hoofed’ mammals make up the Perissodactyla.
- Some later authors have favored placement of Cetacea closer to Perissodactyla among living orders.
- Artiodactyls stand in contrast to the ‘odd-toed ungulates,’ the Perissodactyla, in which the plane of symmetry runs down the third toe.
