Ungulates are a clade of mammals that are distinguished by their having hooves. Most are herbivorous, and many are large. How many of the extant taxonomic families of ungulates can you name?
Although cladistically ungulates, cetaceans (whales, dolphins, and porpoises) are excluded.
Extinct families are also excluded.
Scientific and common names are both accepted, but for common names it must refer to the family in particular (e.g. "bovine" will not work as that refers to a subfamily rather than a family).
