It sounds like the beginning of a joke: what do you get when you cross a camel with a llama? You get a cama, thanks to the efforts of the Camel Reproduction Center in Dubai. Camas are said to be friendlier than a camel and hardier than a llama. The cama pictured here is named Rama and was born in 1998. Three others have been produced since then, and as a camel and a llama have the same number of chromosomes, it is believed that camas may be able to reproduce. The cama is just one of several animals profiled in the Cracked article The 5 Coolest Pets Humanity Has Bred into Existence. Link
