Dorsale stekels (totaal) : 10; Dorsale zachte stralen (totaal) : 10; Anale stekels: 3; Anale zachte stralen: 7 - 8. This species is distinguished from its congeners by the following set of characters: basioccipital foramen present (vs. absent); proximal middle radial of anal-fin pterygiophore slender with trough on anterodorsal portion (vs. no trough); lateral line scales 36-42 (vs. 44-48 in N. atlanticus, 47-51 in N. pacificus); only cycloid scales on body (vs. ctenoid and cycloid in N. atlanticus); small canine teeth on side of lower jaw (vs. villiform teeth in N. atlanticus) (Ref. 55728).
Marketed fresh or made into fishmeal (Ref. 3288).
