Oribi

The oribi is a small, slender antelope; it reaches nearly 50–67 centimetres (20–26 in) at the shoulder and weighs 12–22 kilograms (26–49 lb). The head-and-body length is typically between 92 and 110 centimetres (36 and 43 in). Sexually dimorphic, males are slightly smaller than females (except for O. o. ourebi, in which females are smaller). This antelope features a slightly raised back, and long neck and limbs. The glossy, yellowish to rufous brown coat contrasts with the white chin, throat, underparts and rump. The bushy tail, brown to black on the outside, has white insides (except in O. o. hastata, that has a completely black tail). The subspecies show some variation in colouration; O. o. ourebi is a rich rufous, while O. o. hastata is yellower. Only males possess horns; the thin, straight horns, 8–18 centimetres (3.1–7.1 in) long, are smooth at the tips and ringed at the base. The maximum horn length, 19.1 centimetres (7.5 in), was recorded in 1998 from Malawi. The oribi has at least six different, well-developed scent glands (such as the prominent preorbital glands near the eyes). The body has several modifications, such as the large fossae below the eyes, to accommodate such a large number of glands. Females have four teats.
