- An Arabian camel or dromedary (Camelus dromedarius)
- Yemen ()
The Bactrian camel (Camelus bactrianus) normally has two humps, while the Arabian camel or dromedary (Camelus dromedarius) normally has just one. During the early 1970s, however, German zoologist Dr Bernhard Grzimek documented an apparently unique, freak dromedary that possessed no fewer than four distinct, fully formed humps. Its very fortunate original owner sold the animal for almost $10,000 in the town of Hodeida, Yemen.
