They grasp forage with their split upper lip and lower incisors. As a result of this grazing technique, they do not destroy pastures. Basically, llamas communicate by using a variety of unique, subtle body postures and vocalizations. The most common sound made is a soft humming. Communicating via body language is done with use of ears, tail and neck.
Llamas are scent oriented, and from birth, they use communal dung piles.
Llamas come in all colors, markings, shapes, sizes and price ranges. There is definitely a llama to fit every individual taste and interest. The bad reputation that llamas have received for spitting is unfair. Llamas sometimes spit at one another at feeding time. Those that spit at humans have usually been teased, intimidated or frightened.
