Andean pack animal is a term that describes the various types of domesticated animals used for transportation and carrying loads in the Andean region. These animals include llamas, alpacas, vicuñas, and guanacos. Though they are all classified as Andean pack animals, there are differences in their size, strength, and temperament that make some better suited for certain tasks than others. For example, llamas are larger and more robust, making them suitable for carrying heavy loads over long distances. Alpacas, on the other hand, are smaller and better suited for carrying lighter loads, while vicuñas and guanacos are primarily used for their wool. Regardless of the species, Andean pack animals are essential to the livelihoods of many people in the region.
