A large ruminant used in Asia and Africa for carrying burdens and for riding. The camel is remarkable for its ability to go a long time without drinking. Its hoofs are small, and situated at the extremities of the toes, and the weight of the animal rests on the callous. The dromedary (Camelus dromedarius) has one bunch on the back, while the Bactrian camel (C. Bactrianus) has two. The llama, alpaca, and vicuña, of South America, belong to a related genus (Auchenia).
