Biologi     Ordlista (t.ex. epibenthic)

Inhabits deep oceanic and continental slope waters of the tropics through the temperate regions in both hemispheres. Feeds in deeper waters (Ref. 122680) on crustaceans and cephalopods, but prefers squid (Ref. 1394). Feeding strategy involves synchronized, individual hunting for non-schooling prey such as deep-sea squids (Ref. 130961).
