Flathead Mullet (mugil Cephalus): Species Account
Physical characteristics: Flathead mullets commonly reach a length of 14 inches (35 centimeters) from the tip of the snout to the end of the body but may reach 47 inches (120 centimeters) from the tip of the snout to the end of the tail. Fat covers a large portion of the eyes. Flathead mullets have several rows of teeth on the edges of the lips. The body is olive green on the back and silvery on the sides and belly, and there are about seven dark stripes along the sides. The pelvic fin, anal fin, and lower lobe of the tail fin are yellowish in some fish. The pelvic fins are the rear pair, corresponding to the rear legs of four-footed animals.
Geographic range: Flathead mullets live all over the world in warm water.
Habitat: Flathead mullets live in inshore marine waters, estuaries, lagoons, and rivers, usually in shallow water, rarely moving deeper than 656 feet (200 m). Adults may move far upriver.
Diet: Larvae and young flathead mullets feed on plankton.
Larvae (LAR-vee) are animals in an early stage and must change form before becoming adults. Adults feed on invertebrates and algae (AL-jee), plantlike growths that live in water and have no true roots, stems, or leaves. These fish may gulp and filter sediment, browse over submerged surfaces, or feed at the surface.
Behavior and reproduction: Adult flathead mullets form schools and sometimes jump. Adults move offshore in unorganized groups to spawn, usually at night, before returning to near-shore waters with a low salt content or freshwater. The young remain in sheltered bays, lagoons, and estuaries until they are old enough to reproduce.
Flathead mullets and people: Flathead mullets are important food fish in many parts of the world.
Conservation status: Flathead mullets are not threatened or endangered. ∎
