What is an even-toed and an odd-toed hoof?
A hoof is the end, or tip, of an ungulate mammal’s foot. It is like shoes (made of thick keratin) to protect their feet.
Some ungulates have even-toed hooves, such as cattle, deer, pigs, goats, sheep, camels, hippopotamuses, llamas, alpacas, giraffes, and antelopes (called artiodactyls).
Some ungulates have odd-toed hooves, such as horses, zebras, rhinoceroses, and tapirs (called perissodactyls, or equids).
