Usually live 305 m or more below the surface but move upward in the water at night, sometimes to relatively shallow depths. Are believed to be rapid swimmers, skillful at avoiding nets, which would account for the scarcity of large adults in research collections. Juveniles feed heavily on crustaceans, while adults feed mainly on fish (Ref. 4525).
