Alpacas and Llamas: The alpaca and the llama are the two animals most closely associated with the Andes. These two species are domestic livestock. There are two wild species, the huanuco and the vicuņa. In the past few decades, there has been lots of interest in the alpaca and llama in the United States because of its unique characteristics, breeding potential and wool.
For decades, the alpaca wool industry has shown potential for providing a steady income for the most impoverished part of the country, the high Andes. But it has never really taken off. The wool merchants of Arequipa seem to keep the trade under their fingers.

They are a combination of household pet, garbage disposal and source of rare protein in the Andes.
