"The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid found on the Indian subcontinent to Vietnam and Peninsular Malaysia, in Sri Lanka, in Luzon Island in the Philippines, and in Borneo. 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. Water buffaloes are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of the dairy cow. The large feral population of northern Australia became established in the late 19th century, and there are smaller feral herds in New Guinea, Tunisia and northeastern Argentina. There are at least 130 million domestic water buffalo, and more human beings depend on them than on any other domestic animal."
