South American lamoid (seealpaca), the smallest species (Vicugna vicugna) in the camel family, found in semiarid grasslands of the central Andes at altitudes of 12,000–16,000 ft (3,600–4,800 m). The remarkably long, soft, lustrous coat is cinnamon to white; a dense, silky, white fleece hangs from the flanks and base of the neck. Vicuñas are about 36 in. (90 cm) high and weigh over 100 lbs (50 kg). Small bands of females, led by a male, graze on low grasses, ruminate while at rest, and spit often and noisily. They mark their territory with communal dung heaps. Vicuñas are untamable but have been hunted for centuries; they are now protected as an endangered species.
