Summary:
A relatively large hatchetfish, found mostly at 200-600 m during the day, migrating to feed mostly in depths of 80-200 m at night.
The silver sides and bioluminescence camouflages the Lovely Hatchetfish, enabling it to hide from predators and prey in the down-welling light of the twilight zone.
