Guanaco
Wild South American camelid, ancestor of the llama.
The guanaco (Lama guanicoe) is a camelid native to South America, closely related to the domesticated llama. It is one of two wild South American camelids, the other being the vicuña, which lives at higher elevations. Guanacos are among the largest terrestrial mammals native to South America today and are valued for their soft wool, which is second only to vicuña wool in luxury fabric.

Lore & Background
Guanacos inhabit the steppes, scrublands, and mountainous regions of South America, including the altiplano of Peru, Bolivia, and Chile, as well as Patagonia and a small population in Paraguay. They live in herds composed of females, their young, and a dominant male, while bachelor males form separate herds of up to 50 individuals. Guanacos are diurnal and can run at 64 km/h, an important defense in open grasslands. Natural predators include pumas and the culpejo (Andean fox). When threatened, guanacos alert the herd with a high-pitched bleat and may spit up to six feet. They also form a shield formation around their young to protect them from foxes. Mating season occurs between December and February, with a single chulengo born after 11.5 months. Male chulengos are chased from the herd at about one year old. The guanaco was independently domesticated by the Mapuche of Mocha Island in southern Chile, producing the chilihueque, which was bred for wool and to pull the plough. This animal disappeared in the 17th century when replaced by Old World sheep and draft animals.
Reader's Guide
The guanaco holds significant ecological and cultural importance in South America. As one of the largest native terrestrial mammals, it plays a key role in grassland and scrubland ecosystems. Its wool is highly prized for luxury fabrics, second only to vicuña wool, and its thick neck skin is used in Bolivia for shoe soles. Conservation concerns include entanglement in fences, especially for yearlings, and habitat threats from woody plant encroachment in Bolivia. The guanaco's ability to survive in extreme environments, such as the Atacama Desert where it eats cactus flowers and lichens that capture fog moisture, underscores its adaptability.
Did You Know?
- A teaspoon of guanaco blood contains about 68 million red blood cells, four times that of a human.
- Guanacos can run at 64 km/h and are excellent swimmers.
- Young guanacos are called chulengos or 'guanaquitos'.
- The guanaco was independently domesticated by the Mapuche of Mocha Island, producing the chilihueque.
Frequently Asked Questions
What is a guanaco?
The guanaco (Lama guanicoe) is a wild camelid that roams the grasslands and highlands of South America. It is the free-ranging relative of the llama and one of only two truly wild camelid species on the continent, the other being the vicuña.
What's the difference between a guanaco and a llama?
Although they look similar, the guanaco is the wild ancestor from which the domesticated llama was selectively bred thousands of years ago. Guanacos are leaner, faster, and live free in the wild rather than being kept by humans for labor or fiber.
Why is guanaco wool so prized?
Guanaco fiber is extraordinarily fine and soft, ranking just behind vicuña wool as the most luxurious natural textile available. Historically, Inca royalty reserved guanaco cloth for the highest-status garments, and today it remains a highly sought-after material in premium fabrics.
How long do guanacos live in the wild?
Under favorable conditions a guanaco can reach an age of about 28 years, which is quite long for a wild ungulate of its size. Predation by pumas and harsh Andean winters are the main factors that typically shorten individual lifespans.
