The term 'llama relatives' refers to two animals related to the llama, the alpaca and the vicuna. The alpaca is a domesticated species of South American camelid, similar in appearance to the llama, but smaller in size. The vicuna is a wild species of South American camelid, also related to the llama, and is the smallest of the camelids. Both the alpaca and the vicuna are valued for their soft, luxurious wool.
