Genera

Lamini (members are called lamines) is a tribe of the subfamily Camelinae. It contains one extant genus with four species, all exclusively from South America: llamas, alpacas, vicuñas, and guanacos. The former two are domesticated species, while the latter two are only found in the wild. None display sexual dimorphism. The four species can interbreed and produce fertile offspring. [1] Additionally, there are several extinct genera.

The digestive system of lamoids allows them to digest certain toxins. [2] Laminoids also lack a gallbladder. [3]

Evolutionary history

Lamines originated during the Miocene in North America, [4] and migrated into South America during the Pliocene and Pleistocene as part of the Great American Interchange. [5] Most species of lamines, including the genera Hemiauchenia and Palaeolama and all North American species, became extinct at the end of the Pleistocene around 12,000 years ago as part of the Quaternary extinction event along with most other large mammals in the Americas. [5]

Characteristics and distribution

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.

<span class="mw-page-title-main">Vicuña</span> Wild South American camelid

The vicuña or vicuna is one of the two wild South American camelids, which live in the high alpine areas of the Andes; the other camelid is the guanaco, which lives at lower elevations. Vicuñas are relatives of the llama, and are now believed to be the wild ancestor of domesticated alpacas, which are raised for their coats. Vicuñas produce small amounts of extremely fine wool, which is very expensive because the animal can only be shorn every three years and has to be caught from the wild. When knitted together, the product of the vicuña's wool is very soft and warm. The Inca valued vicuñas highly for their wool, and it was against the law for anyone but royalty to wear vicuña garments; today, the vicuña is the national animal of Peru and appears on the Peruvian coat of arms.

<i>Lama</i> (genus) Genus of mammals

Lama is a genus containing the South American camelids: the wild guanaco and vicuña and the domesticated llama, alpaca, and the extinct chilihueque. Before the Spanish conquest of the Americas, llamas, alpacas, and chilihueques were the only domesticated ungulates of the continent. They were kept not only for their value as beasts of burden, but also for their flesh, hides, and wool.

The term puna encompasses diverse ecosystems of the high Central Andes above 3200–3400 m.

A huarizo, also known as a llapaca, is a hybrid cross between a male llama and a female alpaca. Misti is a similar hybrid; it is a cross between a male alpaca and a female llama. The most common hybrid between South American camelids, huarizo tend to be much smaller than llamas, with their fibre being longer. Huarizo are sterile, but recent genetic research conducted at the University of Minnesota Rochester suggests that it may be possible to preserve fertility with minimal genetic modification. However, many owners have reported that their Huarizos and Mistis are fertile.

Animal fibers are natural fibers that consist largely of certain proteins. Examples include silk, hair/fur and feathers. The animal fibers used most commonly both in the manufacturing world as well as by the hand spinners are wool from domestic sheep and silk. Also very popular are alpaca fiber and mohair from Angora goats. Unusual fibers such as Angora wool from rabbits and Chiengora from dogs also exist, but are rarely used for mass production.

<span class="mw-page-title-main">Alpaca fiber</span> Natural fiber

Alpaca fleece is the natural fiber harvested from an alpaca. There are two different types of alpaca fleece. The most common fleece type comes from a Huacaya. Huacaya fiber grows and looks similar to sheep wool in that the animal looks "fluffy". The second type of alpaca is Suri and makes up less than 10% of the South American alpaca population. Suri fiber is more similar to natural silk and hangs off the body in locks that have a dreadlock appearance. While both fibers can be used in the worsted milling process using light weight yarn or thread, Huacaya fiber can also be used in a woolen process and spun into various weight yarns. It is a soft, durable, luxurious and silky natural fiber.

<i>Hemiauchenia</i> Extinct genus of mammals

Hemiauchenia is a genus of laminoid camelids that evolved in North America in the Miocene period about 10 million years ago. This genus diversified and entered South America in the Late Pliocene about three to two million years ago, as part of the Great American Biotic Interchange. The genus became extinct at the end of the Pleistocene. The monophyly of the genus has been considered questionable, with phylogenetic analyses finding the genus to paraphyletic or polyphyletic, with some species suggested to be more closely related to living lamines than to other Hemiauchenia species.

Camelini is a tribe of camelids including all camelids more closely related to modern camels (Camelus) than to Lamini, from which camelines split approximately 17 million years ago. The tribe originated in North America, with the genus Paracamelus migrating over the Bering Land Bridge into Eurasia during the Late Miocene, around 6 million years ago, becoming ancestral to Camelus. The last member of Camelini in North America was Camelops, which became extinct as part of the Quaternary extinction event at the end of the Late Pleistocene, around 12,000 years ago.

The Huacaya alpaca is a breed of alpaca that has a unique appearance and fiber quality. This breed is the most popular alpaca breed with population numbers reaching 2.8 million in Peru alone. They share biological components with other species in the Camelidae family. Their digestive tract, nutrition requirements, and herd behavior mirror that of all camelids. They also survive amidst similar predation, poison, and disease threats that endanger all camelids alike.

Inca animal husbandry refers to how in the pre-Hispanic andes, camelids played a truly important role in the economy. In particular, the llama and alpaca—the only camelids domesticated by Andean people— which were raised in large-scale houses and used for different purposes within the production system of the Incas. Likewise, two other species of undomesticated camelids were used: the vicuña and the guanaco. The guanacos were hunted by means of chacos.
