| Σχόλια | Cosmopolitan in tropical, subtropical to temperate waters. In the South Pacific Ocean the species is common in the mixed waters of the subtropical frontal zone and the sub-Antarctic waters. Adults occupy the upper mesopelagic zone during the day and then undergo diel vertical migration into epipelagic waters at night: off Bermuda, closing-net studies showed it occurs principally at 375 to 500 m during the day and ascends to 75 to 175 m at night; in open net studies off the Canary Islands, found them at 400 to 800 m during the day and 50 to 100 m to 200 m at night. The species occurs in the eastern Mediterranean Sea/northern Aegean Sea in the mesobathyal basins (Ref. 97142). |
