Llamas are domesticated South American animals related to alpacas, guanacos, and vicunas. They belong to the camelid family and are known for their long necks, large eyes, and thick woolly coats. Llamas are primarily used as pack animals and for their wool, which is soft and warm. They can weigh between 280 to 450 pounds and stand about 5.5 to 6 feet tall at the head. These animals are social creatures that live in herds and communicate through a variety of sounds, including humming and clucking. Llamas are herbivores, primarily grazing on grass and other vegetation. They are also known for their gentle temperament, making them popular in petting zoos and as therapy animals.
