Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais (total) : 78 - 92; Espinhos anais: 0; Raios anais : 58 - 69; Vértebras: 39 - 42. Dorsal origin above eye. Caudal rounded. Pectoral small, bluntly pointed.
Body shape (shape guide): short and / or deep.
Common in shallow water on soft, silty bottom. Moves into shallow water in summer and to deeper water in winter (Ref. 6885). Spawning adults exhibit north-south migrations (Ref. 6885). Feeds on chaetopod marine worms, young herring, shrimps, and sand dollars (Ref. 6885). A tasty food fish, sometimes marketed (Ref. 2850). Also used for mink food (Ref. 2850).
