Characteristics and distribution

The llama (''Lama glama'') is the largest of the extant laminoids and weighs with a height of at the shoulder. Llamas are not a natural species; rather, they were domesticated by the Peruvians and Bolivians of the highlands. Commercial trade led to the llama's current abundance in Colombia, Ecuador, Peru, Bolivia, Chile, Paraguay, and northeast Argentina. There are bands of llamas in the United States, Europe, Japan, and New Zealand. The color and length of the llama's wool is variable, depending on the race. The diameter of llama wool's fiber varies between 20 and 80 micrometers, depending on whether the llamas were raised for its wool or as a
