Marine Living

The open ocean, or pelagic zone, is the area of the ocean outside of coastal areas, and where you’ll find some of the biggest marine life species. The sea floor (demersal zone) is not included in the pelagic zone.

The pelagic zone is separated into several subzones depending on water depth:

Epipelagic zone (ocean surface to 200 meters deep)Mesopelagic zone (200-1,000m)Bathypelagic zone (1,000-4,000m)Abyssopelagic zone (4,000-6,000m)Hadopelagic zone (deep ocean trenches, greater than 6,000m).
