Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 0; Taggstrålar i analfenan 0. Upper limb or first gill arch with 2 (rarely 3) rakers. First dorsal in with an elongated ray.

Biologi     Ordlista (t.ex. epibenthic)

Found on soft, muddy bottoms of the continental shelf and upper slope. It is mostly found at 180 m. Mature fish migrate inshore in the northern Gulf of Maine in summer, disperse in autumn, and move into deepest areas in winter. Feed on small crustaceans, squids and small fish. Utilized fresh, smoked or frozen; eaten steamed, microwaved and baked (Ref. 9988). Exported to Europe (Ref. 9988).
