Alpacas are the smallest of the domesticated camelids and are cousins of camels, llamas, guanacos and vicuña. Alpacas are native to the central and southern Andes Mountains in South America but are farmed all over the world. They have slender bodies and use their long and shaggy neck to spot predators. Alpacas are famous for their fleece, a special type of wool called fiber. Fiber is one of the warmest and finest textiles in the world. Alpaca fleece is used to make luxurious clothing and blankets.
