Espinhos dorsais (total) : 0; Raios dorsais (total) : 24 - 28; Raios anais : 33 - 39. Dorsal fins widely spaced, interspace between second and third fins longer than base length of first dorsal fin.

Biologia     Glossário (p.ex. epibenthic)

Found over the continental slope and shelf to more than 1000 m, but more common at 300-400 m. Feeds mostly on small crustaceans but large individuals also prey on small fish and cephalopods. Makes daily vertical migrations: surface waters at night and near the bottom during the day. Sold fresh and frozen, and also processed as oil and fishmeal (Ref. 1371).
