Llamas, alpacas, and vicunas, along with guanaco which I never saw, are all members of the camelid family.

Doesn't it look like a camel?
Bred to be beasts of burden, llamas are everywhere in Peru, even in cities like Cusco where women and children are constantly pestering you to take their picture with the animal–and then asking you to pay for the privilege. In the Colca Canyon area where a handful of women, accompanied by their children and animals, would display their wares at a roadside pull-off, I never heard one of them ask for money.

Oh, so cute!
Alpacas, on the other hand, were bred to produce fiber and are usually kept in herds. They are smaller than llamas and have straight versus banana-shaped ears. I had a chance to photograph alpacas up close and personal at Awana Kancha in the Sacred Valley. http://awanakancha.com/about.html

Vicuña are even smaller and more delicate looking. They are not domesticated and were declared an endangered species in 1974. I went to two preserves where they are present, but was only able to get one decent photograph.
