Guanacos are graceful animals related to camels. Pronounced "gwa NAH ko," they live throughout South America in dry, open country in the mountains or on the plains. Guanacos have a calm attitude, so people started to domesticate them for use as pack animals. The result is the llama of today, which is the domesticated version of the guanaco—llamas don’t exist in the wild. Another branch of the family tree is the alpaca, which is also a type of domesticated guanaco raised for its soft wool.
