A novel free-living prochlorophyte abundant in the oceanic euphotic zone.

The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live.

However, due to its capacity for photosynthesis, the photic zone has the greatest biodiversity and biomass of all oceanic zones.

This, the deepest oceanic zone, extends from a depth of 6000 metres down to approximately 11000 metres.

The table below illustrates the classification of oceanic zones:

The neritic encompasses the water mass directly above the continental shelves, while the oceanic zone includes all the completely open water.

The oceanic zone begins in the area off shore where the water measures 200 meters (656 feet) deep or deeper.

While it is often difficult for life to sustain itself in this type of environment, some species do thrive in the oceanic zone (Col).

The oceanic zone is subdivided into the epipelagic, mesopelagic, and bathypelagic zones.

All of the light zones can be found in the oceanic zone.
