Deep-sea organisms generally inhabit bathypelagic (1-4 km, 0.6-2.5 mi deep) and abyssopelagic (4-6 km, 2.5-3.7 mi deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200-1,000 m, 650-3,300 ft deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is ...
