difference between alpacas and llamas
llamas have long banana-shaped ears while alpacas have shorter spear-shaped ears. there really are a lot of differences between llamas and alpacas. The llama is roughly twice the size of the alpaca. Most alpacas weigh between 100 and 175 lbs when fully grown. Llamas on the other hand weigh in the neighborhood of 200 to 350 lbs.
Llamas were primarily bred to be pack animals, and alpacas were primarily as fiber producers. An average alpaca stands 34- 36 at the withers (shoulders), whereas a llama stands 42- 48 at the withers. Owners of both llamas and alpacas really notice the size difference when it comes to toenail trimming time.
