Llamas are svelte and cannot be distinguished by color as they come in some 50 different hues. They have long legs, faces and necks and can stand 1.90 meters tall.
Llamas are the most common and strongest of the Andean camelids, and are widely used as beasts of burden, as they can carry on average 40 kg a day on long trips and up to 60 kg on shorter journeys. Its average adult weight is 115 kg, and 11.5 kg at birth.
The llama takes to 348 days to whelp, and while the female reaches sexual maturity, it generally mates from 2-3 years in age. The male, meanwhile, mates at the age of three. The mating and reproduction season comes between January and April, and a month after whelping, the female is ready to mate again. These reproduction characteristics are relatively common for all Andean camelids.
Llamas traditionally come in two varieties, Q'ara (with little fiber) and Ch'aku (woolly); their fiber (technically they grow "fiber" and not "wool") is less dense than that of alpacas, and on average the diameter of its fiber is 28.11 microns (a micron is a measure equivalent to one-millionth of a meter or one-thousandth of a millimeter).
