Mullet, a saltwater food fish. It lives in warm coastal waters throughout the world. There are about 200 species. The mullet is a silvery, torpedo-shaped fish with small, triangular fins. The stomach is gizzardlike, and the much-folded intestine is unusually long. Mullet feed on bottom vegetation. Species of commercial value in North American fisheries are the striped mullet and the white mullet. They are each two to three feet (60 to 90 cm) long and may weigh 15 pounds (7 kg).
The surmullet, or red mullet, of European waters is not a true mullet. It is about 12 inches (30 cm) long and has two whiskerlike feelers under the chin. The Romans considered the surmullet a delicacy.
The striped mullet is Mugil cephalus; white, M. curema. Both belong to the mullet family, Mugilidae. The surmullet is Mullus barbatus of the goatfish family, Mullidae.
