Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 87 - 110; Spine anali: 0; Raggi anali molli: 78 - 93; Vertebre: 62 - 65. Dorsal origin above middle of upper eye. Posterior margin of caudal like a 'V'. Pectoral on eyed side greatly elongated.
A slow-growing species found on sand or mud bottoms (Ref. 2850). Usually discarded by trawlers but sometimes processed into fertilizer (Ref. 27436). Flesh considered tasty (Ref. 27436). Utilized fresh and frozen; eaten steamed, fried, microwaved and baked (Ref. 9988).
