Remarks | Neritic and oceanic species (Ref. 121690). Mostly inhabits waters <500 m in depth on the continental shelf and slope (Ref. 121690). Common in the continental shelf and sometimes can even enter shallow waters and estuaries, particularly during summer (Ref. 121673). Most abundant near the shelf-break front or where other mesoscale oceanographic activity is present. Mature squid may be restricted to deeper offshore waters for successful spawning (Ref. 121689). Feeds on ommastrephid squids, fishes (primarily pilchards; Ref. 275). |
