Differences Between Alpacas and Llamas
Even though they are in the same family, Camelidae, alpacas and llamas are used for different purposes by humans.
Alpacas are used for their fiber while llamas are used as pack animals or in meat production. The average llama is roughly twice the size of the average alpaca. An average alpaca stands 34"- 36" at the withers (shoulders), whereas a llama stands 42"- 48" at the withers. Most alpacas weigh between 100 and 175 pounds when fully grown. Llamas on the other hand weigh in the neighborhood of 200 to 350 pounds with some as heavy as 400 pounds. There are differences in the body and head, especially the shape of the ears. The llama is easily distinguished by its long banana-shaped ears. The alpaca has shorter spear-shaped ears. From the side, llamas generally have a longer face; alpacas have a shorter, more compact appearance. A llama's back is straighter, which makes them good for packing.
. . . All that said, we still think the comparison below is hysterical!
