The dorcas gazelle (Gazella dorcas), also known as the ariel gazelle, is a small and common gazelle. The dorcas gazelle stands about 55–65 cm (1.8-2.1 ft) at the shoulder, with a head and body length of 90–110 cm (3-3.6 ft) and a weight of 15–20 kg (33-44 lb). The numerous subspecies survive on vegetation in grassland, steppe, wadis, mountain desert and in semidesert climates of Africa and Arabia. About 35,000 - 40,000 exist in the wild. The extinct Saudi gazelle from the Arabian Peninsula has been previously considered as a subspecies of the dorcas gazelle.
