Camelids are even-toed ungulates belonging to the family camelidae, and unlike true ruminant animals of the family ruminantia, they only have three stomach compartments instead of four. South American Camelidae are grouped into four species: Vicuna, Guanaco, Llama, and Alpaca. The first two are protected wild species, while the later two species have been domesticated for thousands of years. Llamas and alpacas can succussfully interbreed, and the offspring are called huarizo.
