Main Ref. Roper, C.F.E., M.J. Sweeney and C.E. Nauen, 1984
Remarks Oceanic; occurring in equatorial, southern subtropical, southern peripheral water masses. Paralarvae are epipelagic and mesopelagic; adults are lower epipelagic, mesopelagic and bathypelagic. Predators include the dwarf sperm whale, Kogia sima, off Brazil, pygmy sperm whale, K. breviceps, off New Zealand, the southern elephant seal, Miroungia leonina, and fishes, such as hakes and macrurids.
