The llama (Lama glama) is the largest of the extant laminoids and weighs 130–150 kilograms (290–330 lb) with a height of 109–119 cm (43–47 in) at the shoulder.[6] Llamas are not a natural species; rather, they were domesticated by the Peruvians and Bolivians of the highlands.[7] Commercial trade led to the llama's current abundance in Colombia, Ecuador, Peru, Bolivia, Chile, Paraguay, and northeast Argentina. There are bands of llamas in the United States, Europe, Japan, and New Zealand.
The color and length of the llama's wool is variable, depending on the race. The diameter of llama wool's fiber varies between 20 and 80 micrometers, depending on whether the llamas were raised for its wool or as a pack animal.
The guanaco (Lama guanicoe) is a wild camelid, standing at 100–120 cm (39–47 in) at the shoulder[6] and 150–160 cm (59–63 in) at the head. It can weigh up to 140 kilograms (310 lb).[8] Its pelage is longer than vicuña wool but shorter than that of the alpaca; it is considered to be of excellent quality and has a light brown, reddish, or brown-yellow color.[9] The diameter of its fleece's fibers varies between 16 and 18 micrometers.
90% of the world's guanacos are in Argentina,[9] distributed from the islands of the Beagle Channel and the southern extremity of Patagonia to the Puna grassland in northwestern Argentina. Guanacos can also be found in Bolivia, Chile, Paraguay, and Peru.[10]
The alpaca (Lama pacos), a domestic camelid, weighs between 50 and 65 kg (110 and 143 lb), while its height at the shoulder is 94–104 cm (37–41 in). It is slightly larger than the vicuña. Normally, the alpaca is found in the Andes in Peru and Bolivia, though it also inhabits northern Chile and northwestern Argentina.[6] There are about 3.5 million alpacas in the world. In the 1980s, alpacas started being exported to other countries for farming purposes: they can be found in the United States, Australia, and New Zealand, though the vast majority still reside in South America.[11]
The alpaca is mainly raised for its wool. Out of the domestic camelids, the alpaca produces wool with longer and finer fiber than the llama,[6] with a strand diameter of 18–25 micrometers.[12]
The vicuña (Lama vicugna) is the smallest camelid, with a shoulder height of 75–100 cm (30–39 in) and a weight of 40–60 kg (88–132 lb). Its coat is mainly beige in color and is said to make "the best wool in the world", with the average fiber diameter between 11 and 14 micrometers.[13] Like rodents, the vicuña has continuously-growing incisors. It lives only in areas of high altitude – 3,200 m (10,500 ft) or greater – in the highlands of Argentina, Bolivia, Chile, Peru, and Ecuador.
