What does the name Perissodactyla mean in Greek?

The name Perissodactyla is derived from two Greek words: perissos, which means "odd" or "excessive," and daktylos, which means "finger" or "toe."12

This term was introduced to classify perissodactyls—a group of herbivorous mammals including horses, tapirs, and rhinoceroses—by distinguishing these odd-toed ungulates from the even-toed Artiodactyla.12
