Bos
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. Modern species of cattle are believed to have originated from the extinct aurochs.
Anatomy and morphology
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.
Range and distribution
There are about 1.3 billion domestic cattle alive today, making them one of the world's most numerous mammals. Members of this genus are currently found in Africa, Asia, eastern and western Europe, parts of North America, South America and also in Oceania. Their habitats vary greatly depending on the particular species; they can be found in prairies, rain forests, wetlands, savannas and temperate forests.
