After seeing many llamas and alpacas around Peru and being told a little bit about them by various tour guides, I did a little bit of research to find out some more.
Llama 
Alpaca
Well they are both part of the camelid family. Alpacas have “short spear-shaped ears while llamas have much longer, banana-shaped ears.” Over the years llamas have been bred to be pack animals and for their meat, whereas alpacas have generally been bred for their wool. Llamas are usually larger and heavier than alpacas.
Llamas and alpacas live together in herds. They can cross breed. Their babies are called Huraizo.
The Vicuña is rarest of this family. The clothes made from its wool are some of the most expensive in the world.
Around Arequipa and Cusco, for a small price, you can get your photo taken with a baby llama or alpaca alongside the owner in her Peruvian costume.
