The llama (Lama glama) is a domesticated 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
(5.6 to 5.9 ft) tall at the top of the head, and can weigh between 130 and 200
kg (290 and 440 lb). At birth, a baby llama (called a cria) can weigh between 9
and 14 kg (20 and 31 lb). Llamas typically live for 15–25 years, with some
individuals surviving 30 years or more. They 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, they 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 three 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 seven 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 theUnited States and Canada. Lamoids, or
llamas (as they are more generally known as a group), consist of the vicuña
(Vicugna vicugna, prev. Lama vicugna), guanaco (Lama guanicoe),
Suri alpaca, and Huacaya alpaca (Vicugna pacos, prev. Lama guanicoe pacos), and
the domestic llama (Lama guanicoe glama).
Guanacos and
vicuñas live in the wild, while alpacas – as well as llamas – exist only as
domesticated animals. Although early writers compared llamas to sheep, their
similarity to the camel was soon recognized. They were included in the genus
Camelus along with alpaca in the Systema Naturae (1758) of Linnaeus. They were, however, separated by Cuvier in 1800 under the name of lama along with the guanaco. Alpacas and vicuñas are in genus Vicugna. The genera Lama and Vicugna are, with the two species of true camels, the sole existing representatives of a very distinct section of the Artiodactyla or even-toed ungulates, called Tylopoda, or "bump-footed", from the peculiar bumps on the soles of their feet. The Tylopoda consist of a single family, the Camelidae, and shares the order Artiodactyla with the Suina (pigs), the Tragulina (chevrotains), the Pecora (ruminants), and the Whippomorpha (hippos and cetaceans, which belong to Artiodactyla from a cladistic, if not traditional, standpoint). The Tylopoda have more or less affinity to each of the sister taxa, standing in some respects in a middle position between them, sharing some characteristics from each, but in others showing special modifications not found in any of the other taxa.
