Bos (from Latin bōs: cow, ox, bull) is the genus of wild and domestic cattle. Bos can be divided into four subgenera: Bos, Bibos, Novibos, and Poephagus, but these divisions are controversial. The genus has five extant species. However, this may rise to seven if the domesticated varieties are counted as separate species, and nine if the closely related genus Bison is also included. Most modern breeds of domesticated cattle are believed to have originated from the extinct aurochs.
Most species are grazers, with long tongues to twist the plant material they favor and large teeth to break up the plant material they ingest. They are ruminants, having a four-chambered stomach that allows them to break down plant material.
