Red mullet
(Mullus barbatus)

The red mullet can grow to a standard length of 30 cm (12 in), but a more common length is about half that. The body is somewhat laterally compressed. The snout is short and steep and there are no spines on the operculum. The upper jaw is toothless, but there are teeth on the roof of the mouth and on the lower jaw. A pair of moderately long barbels on the chin do not exceed the pectoral fins in length. The first dorsal fin has eight spines (the first one tiny) and the second dorsal fin has one spine and eight soft rays. This fish is rose-pink, without distinctive markings on its fins.

The red mullet is found in the Mediterranean Sea, the Black Sea, and the northeastern and central eastern Atlantic Ocean, where its range extends from Scandinavia southwards to Senegal, including the Canary Islands, Azores, and Madeira. It is a demersal fish and occurs at depths ranging from 10 to 328 m (30 to 1,080 ft) over muddy, sandy, or gravel bottoms.

The red mullet is carnivorous, the diet consisting mainly of polychaete worms, bivalve molluscs and crustaceans. The barbels are sensory organs and are used to help locate prey. Both young and adult mullet are preyed on by various fish including the angler fish (Lophius piscatorius), the thornback ray (Raja clavata), the common stingray (Dasyatis pastinaca), the school shark (Galeorhinus galeus), the John Dory (Zeus faber) and the European hake (Merluccius merluccius).

Breeding takes place in the spring and summer, with spawning occurring in April and May in the Adriatic Sea, at depths between 60 and 70 m (200 and 230 ft). The larvae soon move to shallower depths and are pelagic, as are the juveniles at first. At a length of about 5 cm (2 in) the juveniles move to the coast and become demersal, often congregating in estuaries, and sometimes swimming a short distance upstream. Later they disperse to muddy, sandy or gravelly substrates, becoming sexually mature at a length of 10 to 14 cm (4 to 6 in) during their first year of life.
