An alpaca (Vicugna pacos) is a domesticated species of South American camelid. It resembles a small llama in appearance. Alpacas are kept in herds that graze on the level heights of the Andes of southern Peru, northern Bolivia, Ecuador, and northern Chile at an altitude of 3,500 m (11,500 ft) to 5,000 m (16,000 ft) above sea level, throughout the year. Alpacas are considerably smaller than llamas, and unlike llamas, they were not bred to be beasts of burden, but were bred specifically for their fiber. Alpaca fiber is used for making knitted and woven items, similar to wool. These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles and ponchos in South America, and sweaters, socks, coats and bedding in other parts of the world. The fiber comes in more than 52 natural colors as classified in Peru, 12 as classified in Australia and 16 as classified in the United States. In the textile industry, "alpaca" primarily refers to the hair of Peruvian alpacas, but more broadly it refers to a style of fabric originally made from alpaca hair, but now often made from similar fibers, such as mohair, Icelandic sheep wool, or even high-quality English wool. In trade, distinctions are made between alpacas and the several styles of mohair and luster. An adult alpaca generally is between 81 and 99 cm in height at the withers. They usually weigh between 48 and 84 kg (106 and 185 lbs).
Alpacas have been domesticated for thousands of years. The Moche people of northern Peru often used alpaca images in their art. There are no known wild alpacas, though its closest living relative, the vicuña (also native to South America), are believed to be the wild ancestor of the alpaca. The alpaca is larger than the vicuña, but smaller than the other camelid species. Along with camels and llamas, alpacas are classified as camelids. Of the various camelid species, the alpaca and vicuña are the most valuable fiber-bearing animals: the alpaca because of the quality and quantity of its fiber, and the vicuña because of the softness, fineness and quality of its coat. Alpacas are too small to be used as pack animals. Instead, they are bred exclusively for their fiber and meat. Alpaca meat was once considered a delicacy by Andean inhabitants. Because of the high price commanded by alpaca on the growing North American alpaca market, illegal alpaca smuggling has become a growing problem. Alpacas and llamas can successfully cross-breed. The resulting offspring are called huarizo, which are valued for their unique fleece and gentle dispositions.

History of the scientific name
The relationship between alpacas and vicuñas was disputed for many years. In the 18th and 19th centuries, the four South American lamoid species were assigned scientific names. At that time, the alpaca was assumed to be descended from the llama, ignoring similarities in size, fleece and dentition between the alpaca and the vicuña. Classification was complicated by the fact that all four species of South American camelid can interbreed and produce fertile offspring. The advent of DNA technology made a more accurate classification possible. In 2001, the alpaca genus classification changed from Lama pacos to Vicugna pacos, following the presentation of a paper on work by Dr. Jane Wheeler et al. on alpaca DNA to the Royal Society showing the alpaca is descended from the vicuña, not the guanaco.
Alpacas are social herd animals that live in family groups consisting of a territorial alpha male, females and their young. Alpacas warn the herd about intruders by making sharp, noisy inhalations that sound like a high-pitched bray. The herd may attack smaller predators with their front feet, and can spit and kick.
