Dromedary

The dromedary camel (/ˈdrɑmədɛɹi/ or /ˈdrɒmədri/) or Arabian camel (Camelus dromedarius) is a large, even-toed ungulate with one hump on its back. First described by Aristotle of Stagira, dromedary was given its binomial name by Carl Linnaeus in 1758. The dromedary is the second largest member of the camel family after the Bactrian camel. The oldest known ancestor of the dromedary is the Protylopus. Males are 1.8–2 m (5.9–6.6 ft) tall and females 1.7–1.9 m (5.6–6.2 ft) tall. Males range from 400–600 kg (880–1,300 lb), while females weigh 300–540 kg (660–1,200 lb). Pelage varies largely in colour, from a dark black to a much lighter shade. The notable hump, measuring 20 cm (7.9 in), is fat bound together by fibrous tissue.
