Water buffalo

The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.

Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
