Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 59 - 70; Épines anales: 0; Rayons mous anaux: 54 - 63; Vertèbres: 52 - 54. A small variably shaped patch of teeth on head of vomer. Pectoral fin extending beyond anal fin origin. Ventral light organ present. Color uniformly brown; fins dark-edged (Ref. 1371). Caudal fin rounded (Ref. 27363).
Highest catches at 235 m. Females attain larger sizes than males. Larger individuals of both sexes move into deeper water. Utilized mainly for fishmeal; can be fried, microwaved and baked (Ref. 9988).
