Llamas are a common sight in South America. They are fairly big (height up to 1.8 meters / 5.9 feet) mammals, and distantly related to the camels. They are not to be confused with Alpacas, who are noticeably smaller. Both are closely related to the Vicuña, which is believed to be the wild ancestor of all new world camelids.

The inhabitants of Paititi probably keep them because of their wool. In the Abandoned Village of Paititi, however, there are some wild Llamas that can even be hunted.
