The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately 200 metres (660 ft) in depth.[1][2] From the point of view of marine biology it forms a relatively stable and well-illuminated environment for marine life, from plankton up to large fish and corals, while physical oceanography sees it as where the oceanic system interacts with the coast.

It extends from the low tide mark to the edge of the
Within the neritic, marine biologists also identify the following:[citation needed]
- The infralittoral zone is the algal-dominated zone down to around five metres below the low water mark.
- The circalittoral zone is the region beyond the infralittoral, which is dominated by sessile animals such as oysters.
- The subtidal zone is the region of the neritic zone which is below the intertidal zone, therefore never exposed to the atmosphere.
Physical characteristics
The neritic zone is covered with generally well-
Life forms
The above characteristics make the neritic zone the location of the majority of sea life.[4] The result is high primary production by photosynthetic life such as phytoplankton and floating sargassum;
