Slender-bodied South American lamoid (Lama guanacoe; see alpaca). The guanaco has long legs and neck, a short tail, and large, pointed ears. It lives in small bands of females, usually led by a male, and grazes on grass and other plants, ranging from the snow line to sea level throughout the Andes Mountains from Peru and Bolivia to Tierra del Fuego. The adult stands 43 in. (110 cm) tall at the shoulder and is pale brown above and white below, with a grayish head. The downy fibre covering the young is valued for textiles, and guanaco pelts are used by the fur industry.

The guanaco (Lama guanicoe) is a camelid animal native to South America that stands between 107 and 122 centimeters (3.5 and 4 feet) at the shoulder and weighs about 90 kg (200 lb). The colour varies very little, ranging from a light brown to dark cinnamon and shading to white underneath. Guanacos have grey faces and small straight ears. They are extremely striking with their large, alert brown eyes, streamlined form, and energetic pace. They are particularly ideal for keeping in large groups in open parklands.
The guanaco is native to the arid, mountainous regions of South America. Guanaco are found in the altiplano of Bolivia, Peru, Ecuador, Colombia, Chile and Argentina. In Chile and Argentina they are more numerous in Patagonian regions, in places like the Torres del Paine National Park, and Isla Grande de Tierra del Fuego in fact has an overpopulation of guanacos. Bolivian Indians have been known to raise guanacos to help them regain their population stability. A guanaco's average life span is 20-25 years.
Current estimates place their numbers at 500,000.
Guanacos are the largest mammal found in South America. They have only one natural predator, the mountain lion or puma. Guanacos will often spit when threatened.
Eleven months later, a single calf, or chulengo, is born. Calves are able to walk immediately after birth. Male calves are chased off from the herd at approximately one year of age.
