The alpaca (Lama pacos) is a species of South American camelid mammal. It is similar to, and often confused with, the llama. However, alpacas are often noticeably smaller than llamas. Both species are believed to have been domesticated from their wild relatives, the vicuña and guanaco. There are two breeds of alpaca: the Suri alpaca and the Huacaya alpaca. Alpacas are considerably smaller than llamas, and unlike llamas, they were not bred to be working animals, but were bred specifically for their fiber. Alpaca fiber is used for making knitted and woven items, similar to sheep's wool. Alpacas communicate through body language. The most common is spitting to show dominance when they are in distress, fearful, or feel agitated. Body language is the key to their communication. It helps to maintain their order. The origin of alpacas is depicted in legend; the legend states they came to be in the world after a goddess fell in love with a man. The goddess' father only allowed her to be with her lover if he cared for her herd of alpacas. On top of caring for the herd, he was to always carry a small animal for his entire life. As the goddess came into our world, the alpacas followed her. Everything was fine until the man set the small animal down, and the goddess fled back to her home. On her way back home, the man attempted to stop her and her herd from fleeing. While he was not able to stop her from returning, he was able to stop a few alpacas from returning. These alpacas who did not make it back are said to be seen today in the swampy lands in the Andes waiting for the end of the world, so they may return to their goddess.
