The dromedary or Arabian camel (Camelus dromedarius) is a large even-toed ungulate with one hump on its back. Its native range is unclear, but it was probably the Arabian Peninsula. The domesticated form occurs widely in North Africa and the Middle East; the world's only population of dromedaries exhibiting wild behaviour is an introduced feral population in Australia.
The dromedary camel is one of the best-known members of the camel family. Other members of the camel family include the llama and the alpaca in South America. The Dromedary has one hump on its back, in contrast to the Bactrian camel which has two. A good mnemonic for remembering which way around these terms apply is this: "Bactrian" begins with "B", and "Dromedary" begins with "D"; "B" on its side has two humps, while "D" on its side has only one hump.
