No, they are not baby llamas.
Many people think when they first see an alpaca that they are baby llamas.
Well, they are not. This article should help by giving you some basic information about the differences between alpacas and llamas. One of the most distinguishing physical characteristics between them is their size. A full grown alpaca weighs approximately 150 pounds, give or take 40. This makes them roughly half to one third the size of a full grown llama.
