Order Perissodactyla, also known as odd-toed ungulates, is a diverse group of animals characterized by the odd number of toes on each of their hind feet. This order includes some of the world's most iconic mammals, including horses, zebras, and rhinoceroses. Despite the use of its scientific name, this group is often referred to as "ungulates," "hoofed animals," or simply "horses" due to the prevalence of this family in our everyday lives. Additionally, this order can be referred to as "Perissodactyls," "Perissodactyl mammals," or by its popular subfamilies, such as the Equidae, the family that includes horses, donkeys, and zebras.
