Alpacas - Neck Length: Approx. 3.8 ft. (1.17 m)

The Alpaca (Lama pacos) is a species of South American camelid mammal. It is similar to, and often confused with, the llama. However, alpacas are often noticeably smaller than llamas. The two animals are closely related and can successfully crossbreed. Both species are believed to have been domesticated from their wild relatives, the vicuña and guanaco. There are two breeds of alpaca: the Suri alpaca and the Huacaya alpaca.

These creatures can be identified by their long, straight ears and rounded backs. They also have large lips, prominent noses, and long, shaggy necks. Their 3.8-ft long necks play two key roles. First, like llamas and vicunas, these animals enjoy eating tree leaves. In order to eat the leaves growing on top of the trees, they developed long necks and legs. Second, their long necks enable them to keep an eye out for predators like coyotes, bears, and mountain lions.
