Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 90 - 116; Épines anales: 0; Rayons mous anaux: 80 - 96; Vertèbres: 50 - 54. Dorsal origin above middle of upper eye. Caudal imperfectly rounded.
Body shape (shape guide): short and / or deep.
Adults occur on mud bottom (Ref. 2850). They move into deep water in winter (Ref. 2850). Produce large amounts of slime which may cover other fishes when caught in trawls (Ref. 4925). Marketed as mink food (Ref. 4925) or as fillet (Ref. 2850).
