Ungulate

Ungulates (meaning roughly "being hoofed" or "hoofed animal") are several groups of mammals most of which use the tips of their toes, usually hoofed, to sustain their whole bodyweight while moving. They make up several orders of mammals, of which six to eight survive. There is some dispute as to whether ungulate should be treated as an actual cladistic (evolution-based) group, or merely a phenetic group (similar, but not necessarily related), in light of the fact that all ungulates do not appear to be as closely related as once believed (see below). Ungulata was formerly considered an order which has been split into Perissodactyla, Artiodactyla, Tubulidentata, Hyracoidea, Sirenia, and Proboscidea. Members of the three orders Perissodactyla, Artiodactyla, and Cetacea are called the 'true ungulates' to distinguish them from 'subungulates' (paenungulata) which include members from the Proboscidea, Sirenia, Hyracoidea, and Tubulidentata orders.

Some commonly known examples of Ungulates living today are the horse, zebra, donkey, cow, rhinoceros, camel, hippopotamus, goat, sheep, giraffe, deer, antelope, and gazelle.
