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 8�13 km (5�8 miles).
The name llama (in the past also spelled 'lama' or 'glama') was adopted by European settlers from native Peruvians.
Llamas appear to have originated from the central plains of North America about 40 million years ago. They migrated to South America about 3 million years ago. By the end of the last ice age (10,000�12,000 years ago), camelids were extinct in North America. As of 2007, there were over 7 million llamas and alpacas in South America and, due to importation from South America in the late 20th century, there are now over 158,000 llamas and 100,000 alpacas in the United States and Canada.
