There are no glands on the face; males have glands that appear to be modified apocrine sweat glands that secrete pungent, coffee-coloured fluid during the rut, located on either side of the neck midline.
The glands generally grow heavier during the rut, and range from 20 to 115 g (0.71 to 4.06 oz). The vagina is 3–3.5 cm (1.2–1.4 in) long and has well-developed Bartholin's glands.
Males typically weigh between 400 and 600 kg (880 and 1,320 lb), and females weigh between 300 and 540 kg (660 and 1,190 lb).
The species' distinctive features include its long, curved neck, narrow chest, a single hump (compared with two on the Bactrian camel and wild Bactrian camel), and long hairs on the throat, shoulders and hump. The hump, 20 cm (7.9 in) tall or more, is made of fat bound together by fibrous tissue.
Adult males range in height between 1.8 and 2 m (5.9 and 6.6 ft) at the shoulder; females range between 1.7 and 1.9 m (5.6 and 6.2 ft).
Males typically weigh between 400 and 600 kg (880 and 1,320 lb); females range between 300 and 540 kg (660 and 1,190 lb).
In the wild, the dromedary inhabited arid regions, including the Sahara Desert.
