Found over the continental shelf and slope. Feeds on southern anchovy and mid-water benthic prey such as squid and lantern fishes (Ref. 1394). Found over the continental shelf and slope. Feeds on southern anchovy and mid-water benthic prey such as squid and lantern fishes (Ref. 1394). Observed to have a common New Zealand octopus Pinnoctopus cordiformis attached to its dorsal area and caudal peduncle at different encounters. One encounter reported a group of dolphins to seem to be playing with the octopus. The dolphins were observed pulling and biting chunks from the octopus’s arms but not from its mantle; it was unclear if the tissue was eaten (Ref. 122722).
