The guanaco (Lama guanicoe) is a camelid native to South America that stands between 107 and 122 cm (3.5 and 4 feet) at the shoulder and weighs about 90 kg (200 lb). The colour varies very little (unlike the domestic llama), 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. The name guanaco comes from the South American language Quechua word "wanaku" (old spelling, "huanaco").[2] Young guanacos are called chulengo(s).
