Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 78-92; Espinas anales 0; Radios blandos anales: 58 - 69; Vértebra: 39 - 42. Dorsal origin above eye. Caudal rounded. Pectoral small, bluntly pointed.

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).
