Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 2; Espinhos anais: 0. Ventral leading edge of snout and narrow ventromedian strip on underside naked, head otherwise completely scaled. Scales deciduous, with small, short, conical spinules in 6 to 9 parallel rows. Overall color is brownish to bluish; trunk bluish to blackish; fins blackish; mouth dusky; gill cavities blackish.
Apparently found deeper in the northern part of its range. Copepods (80%) and polychaetes (62%) have the highest proportions in specimens examined from the slope off northwestern Africa. Other crustaceans and a few fish formed the remainder of the diet. This species like the majority of macrourines, depends on a mixed diet of benthic and pelagic organisms (Ref. 6219).
