The llama (/ˈlɑːmə/; Spanish pronunciation: [ˈʎama]) (Lama glama) is a domesticated South American camelid, widely used as a meat and pack animal by Andean cultures since the Pre-Columbian era. Llamas are social animals and live with others as a herd. Their wool is soft and contains only a small amount of lanolin. Llamas can learn simple tasks after a few repetitions. When using a pack, they can carry about 25 to 30% of their body weight for 8 to 13 km (5–8 miles). The name llama (in the past also spelled 'lama' or 'glama') was adopted by European settlers from native Peruvians. A full-grown llama can reach a height of 1.7 to 1.8 m (5 ft 7 in to 5 ft 11 in) at the top of the head, and can weigh between 130 and 272 kg (287 and 600 lb). At maturity, males can weigh 94.74 kg, while females can weigh 102.27 kg. At birth, a baby llama (called a cria) can weigh between 9 and 14 kg (20 and 31 lb). Llamas typically live for 15 to 25 years, with some individuals surviving 30 years or more.[better source needed] (Source: Wikipedia.org, CC BY-SA)
