Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 0; Mjukstrålar i ryggfenan (totalt): 87-110; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 78 - 93; Ryggkotor: 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).
