The largest member of the family Camelidae is the dromedary or one-humped camel (Camelus dromedarius), with a head and body length of 2.3-3.5 m (7 ft 6 in–11 ft 5 in), a tail length of 55 cm (21 in),a shoulder height of 1.8-2.1 m (6 ft–6 ft 10 in) (maximum 2.4 m 7 ft 10 in) and a weight of 450–690 kg (992–1,521 lb). It is native to the Middle East, but survives today as a feral animal only in Australia and Spain, and as a domestic animal elsewhere.
FYI: Incredibly, the world's tallest man, Robert Wadlow (USA), was taller, measuring 2.72 m (8 ft)!
This species of camel is not the largest artiodactyl (even-toed ungulate mammal), as the giraffe is taller and the hippo is heavier.
