Above the neritic zone lie the intertidal (or eulittoral) and supralittoral zones; below it the continental slope begins, descending from the continental shelf to the abyssal plain and the pelagic zone. Within the neritic, marine biologists also identify the following: [citation needed] The infralittoral zone is the algal-dominated zone down to ...
The littoral zone, also called litoral or nearshore, is the part of a sea, lake, or river that is close to the shore. [1] In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely inundated), to coastal areas that are permanently submerged — known as the foreshore — and the terms are often used interchangeably.
Ocean surfaces occupy 72% of the Earth's total surface. They can be divided into surfaces of the relatively shallow and nutrient rich coastal areas above the continental shelves (light blue), and surfaces of the more expansive and relatively deeper but nutrient poor ocean that lies beyond (deep blue).
The European squid is a neritic, semidemersal species, which undertakes distinct horizontal and vertical migrations, depending on the environment. In the Adriatic Sea , European squid can be found above various substrates, from sandy through to the muddy bottoms. [ 4 ]
The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
Located in the submerged coastal zone of the Red River Delta, it has been declared as a Ramsar Wetland site. [ 31 ] [ 32 ] It has 120 species of vascular plants and 111 species of water plants. As a migratory bird habitat, it is a staging and wintering area for shorebirds, gulls and waterfowl in the coastal zone of the Red River Delta.

Yinggehai basin is lies at the southern end of the Red River fault zone, located at the Gulf of Tonkin.The tectonic origin of Yinggehai basin is controversial. [3] However, it is generally agreed that the basin is opened by the southeastward slip and clockwise rotation of the Indochina block along the Red River fault zone, [4] and that the basin is formed by deformation related to the strike ...
