Artiodactyls exhibit a great deal of variation in physical appearance. Body mass ranges from 4000 kg in hippos to 2 kg in lesser Malay mouse deer. Height ranges from 5 m in giraffes to 23 cm in lesser Malay mouse deer. Most artiodactyls have laterally positioned eyes, often with long eyelashes.
Feb 1, 2018 · Even-toed hoofed mammals (Artiodactyla), also known as cloven-hoofed mammals or artiodactyls, are a group mammals whose feet are structured such that their weight is carried by their third and fourth toes. This distinguishes them from the odd-toed hoofed mammals, whose weight is borne primarily by their third toe alone.
Contents. Home Science Mammals Hoofed Mammals. Evolution and paleontology. The artiodactyls can be traced back to a probable descent from a group of early generalized mammals called condylarths and were certainly distinct by the Eocene Epoch, which ended about 33.9 million years ago.
