The dromedary, also called the Arabian camel, is a large, even-toed ungulate with one hump on its back. It is one of the three species of camel that was given its current binomial name by Carl Linnaeus in 1758. The dromedary is the largest camel after the Bactrian camel; adult males stand 1.8–2 m (5.9–6.6 ft) at the shoulder, while females are 1.7–1.9 m (5.6–6.2 ft) tall. 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 long hairs on the throat, shoulders and hump. The coat is generally a shade of brown. The hump, 20 cm (7.9 in) tall or more, is made of fat bound together by fibrous tissue.
