The llama (Lama glama) is a South American camelid, widely used as a meat and pack animal by Andean cultures since pre-Hispanic times. The height of a full-grown, full-size llama is 1.7 to 1.8 m (5.5 to 6.0 ft) tall at the top of the head, and can weigh between 130 to 200 kilograms (280 to 450 lb). At birth, a baby llama (called a cria) can weigh between 9 and 14 kilograms (20 and 30 lb). Llamas can live for a period of about 20–30 years depending on how well they are taken care of. Llamas are very social animals and live with other llamas as a herd. The wool produced by a llama is very soft and lanolin-free. Llamas are intelligent and can learn simple tasks after a few repetitions. When using a pack, llamas can carry about 25% to 30% of their body weight for several miles. Reference: wikipedia
