Dogfish

sharks

Dogfish, any of various small sharks of the family Squalidac. Dogfish rarely reach 5 ft (1.5 m). They have the ugly heads and rough skins of the typical sharks and feed on the bottom of the sea, catching worms, shrimps, fish, and mollusks. The eggs are laid in horny cases. Dogfish are sold as grayfish for human consumption, and their flesh is used as a fertilizer. At one time an oil was extracted from them. They are now best known as subjects for dissection classes.
