Llamas appear to have originated from the central plains of North America about 40 million years ago.
They migrated to South America about 3 million years ago.
By the end of the last ice age (10,000–12,000 years ago), camelids were extinct in North America.
Like other camelids, llamas have long necks and limbs, rounded muzzles, protruding lower incisors, and a cleft upper lip. The height of an adult llama ranges from 0,92 to 1,6 m. It can weigh from 130 to 155 kg.
Llamas are intelligent and social animals, living in groups of up to 20 individuals led by a dominant male.
They are polygamous animals – all the females in the group mate with the dominant male.
Llamas browse on low shrubs, lichens, and mountain vegetation (especially on grass). They are ruminant animals and, because of their small digestive tract capacities, the young growing llamas require a greater concentration of nutrients than mature animals.
Llamas are polygamous animals – all the females in the group mate with the dominant male. They usually mate during late summer or early autumn. After a gestation period of about 360 days, the females give birth to a single cria almost every year.
