There 143 living species in this family. They include cattle, goats, sheep and antelopes. The family is widespread, living in all continents except the southern continents South America, Australia and Antarctica.

They are all ruminants, with the double stomach system of digesting vegetation, which is most efficient. The family originated in the Miocene, and is now very successful. Their success is probably helped by their digestive system. The group includes the three domestic animals cows, sheep and goats.
