The lamoids are a group of South American camelids comprising llamas, alpacas, guanacos, and vicuñas. Llamas and alpacas are domestic and have thick coats in a variety of colors. Guanacos and vicuñas are wild. They are light brown with white underneath.
Alpacas (Vicugna pacos), which are descended from vicuñas, are smaller than llamas, standing about 0.9 meters at the withers. Compared to llamas, they have shorter heads and shorter, straighter ears. Alpacas also have a thick tuft of fur on top of the head, which is usually absent in llamas. Alpacas are too small to be used as pack animals. Instead, they are bred for their warm, soft, silky fleece, which is finer than llama fiber.
