Bubalus species comprise the domestic
water buffalo (B. bubalis), the
wild water buffalo (B. arnee), the
tamaraw (B. mindorensis), the lowland
anoa (B. depressicornis), and the mountain anoa (B. quarlesi). The latter two anoa species were proposed to form a subgenus within Bubalus.
Kidney of a Bubalus
Smith described Bubalus as low in proportion to the bulk with very solid limbs, a small
dewlap and a long, slender tail; the head is large with a strong convex-shaped narrow forehead, large eyes and funnel-shaped ears; horns are lying flat or bending laterally with a certain direction to the rear; the female udder has four
mammae.Lydekker added that the line of back is nearly straight with 13 pairs of ribs; the tail is tufted and reaching about to the hocks; the horns are more or less markedly triangular for the greater part of their length and situated low down on the skull; the muzzle is broad, and the hair sparse in adults.
