 family. It is 30 in. (75 cm) high at the shoulder, with a long, slender neck and pale, fawn coloring. Vicuñas live in herds on high plateaus of the Andes, at altitudes of 14,000 to 18,000 ft (4,300–5,500 m); they feed on grasses and other vegetation.

Their fleece is exceptionally soft and silky, and in the time of the Incas was reserved for royal robes. The vicuña has never been successfully domesticated; wild herds were rounded up for shearing. Hunted to the verge of extinction for its wool and flesh, it is now protected and has recovered. Today wool is harvested from animals in the wild and others confined to ranches or enclosed ranges.

The vicuña is classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Vicun̄a

 

(Vicugna vicugna), a mammal of the family Camelidae. It is 70-90 cm tall, about 1.5 m long, and weighs up to 65 kg. The body is covered with short but soft thick fur consisting mainly of downy hairs. In the adult animal it is rust-colored on the back and sides and light gray on the underside. The fleece weighs 800-1,000 g.

Vicun̄as live in small herds in the high-mountain regions of the Andes. The female bears one offspring. At the beginning of the 19th century Vicun̄as were rather common in Ecuador, Peru, Bolivia, and Chile. Their area has been significantly diminished as a result of predatory extermination. They have been best preserved in some remote provinces of Peru.
