Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 59 - 70; Spine anali: 0; Raggi anali molli: 54 - 63; Vertebre: 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).
Body shape (shape guide): elongated; Cross section: oval.
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).
