The llama is a domesticated South American camelid, known for its long neck and woolly coat. They are primarily found in the Andes mountains and are closely related to alpacas, guanacos, and vicunas. Llamas are used as pack animals and for their soft wool, which is often spun into yarn. Llamas are social animals that live in herds and communicate through a variety of sounds, including humming and alarm calls. They are herbivores, primarily grazing on grass and other vegetation. Their gentle nature makes them popular in agricultural settings and as therapy animals.
