Remarks | High-oceanic and mesopelagic, found in 525-725 m during the day and in 10-150 m at night (Ref. 4066). Migrates in a diel pattern, residing during daytime at depths of extremely low oxygen levels (0.1 ml Oxygen/liter). Appeared to be opportunistic feeder that preys on a comparatively narrow food spectrum (Ref. 27395). |
