上海街头看到这个宠物 大概是羊驼（好像也叫驼羊） 啥都可以是宠物 Llamas and alpacas have been used by humans for transportation and fleece production for a few thousand years. Both species are primarily found in Peru and Bolivia and are part of the camel family, Camelidae. Alpacas and llamas are two of the four lamoid species—the other two species, vicuña and guanaco, are their wild cousins. Interestingly, all four species are able to interbreed and create fertile offspring. While often conflated, alpacas and llamas differ in key ways. The most-distinguishing physical differences between alpacas and llamas are their size, their hair, and their face shapes. Also, they differ in disposition, which affects the way humans have used them over the years. The most-noticeable difference between the two animals is their sizes. Alpacas are smaller, around 90 cm (35 inches) high at the shoulder and between 55 and 65 kg (121 to 143 pounds). Llamas are the biggest lamoid at about 120 cm (47 inches) at the shoulder and about 113 kg (250 pounds). So llamas are going to be a lot bigger than their cousins. Their faces are also dissimilar: alpacas have small, blunt faces with short ears, while llamas have more-elongated faces with banana-sized ears.
