  1. The pelagic (or open ocean) zone is divided into a number of sub-zones: Epipelagic (surface to 200 m): the illuminated surface zone where there is enough light for photosynthesis. Because of this, plankton, and the food chain which feeds on it, are in this zone. The top predators are fish such as tuna and many sharks.

    Oceanographers have divided the ocean into zones based on how far light reaches. All of the light zones can be found in the oceanic zone. The epipelagic zone is the one closest to the surface and is the best lit.

    Learn about the pelagic and benthic zones of oceans. Follow me on a journey to visit the different zones of the ocean. As we travel, you will learn about two types of zones: the pelagic and benthic zones. Pelagic zones are zones of oceanic waters. Benthic zones are areas of the bottom, or topography of the ocean.

    The pelagic zone consists of the water column of the open ocean and can be further divided into regions by depth. The word pelagic is derived from Ancient Greek πέλαγος (pélagos) 'open sea'. The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom.
