Karakul, sheep breed of central or west Asian origin, raised chiefly for the skins of very young lambs, which are covered with glossy, tightly curled black coats and are called Persian lamb in the fur trade. The wool of mature Karakul sheep, classified as carpet wool, is a mixture of coarse and fine fibres, from 6 to 10 inches (15 to 25 cm) long, of colours varying from black to various shades of brown and gray. The Karakul was first imported into the United States in 1909.
