Perissodactyls are a group of mammals characterized by an odd number of toes on their feet. This group includes animals like horses, zebras, and rhinoceroses. They are primarily herbivorous and have specialized digestive systems to process tough plant materials. The term "perissodactyl" comes from Greek words meaning "uneven toes." Unlike artiodactyls, which have an even number of toes, perissodactyls typically have one or three. This unique toe structure influences their locomotion and habitat preferences, allowing them to thrive in various environments.
