Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 3; Raggi dorsali molli (totale) : 25 - 27; Spine anali: 0; Raggi anali molli: 24 - 26. Scales enlarged above the pectoral fin base and just behind the gill slit to form a flexible tympanum; scales of posterior body with prominent keels, forming longitudinal ridges. A prominent groove in the skin extending anteriorly from front of eye for a distance of about 1 eye diameter. Caudal peduncle depressed. Caudal fin rays of adults prolonged above and below.
Inhabit coastal areas, usually found over muddy and sandy bottoms, also around reefs, together with the sponges and algae (Ref. 5213). Adults on deep coastal slopes and usually seen swimming high above the bottom, sometimes found in estuaries. Juveniles in sheltered coastal bays and estuaries with outcrops of rubble or debris on open substrates (Ref. 48637). Feed on benthic animals (Ref. 9769). Oviparous (Ref. 205). Also caught with vertical long-lines (Ref. 9770). Marketed fresh and dried-salted (Ref. 9770).
