Coastal reef.
pelagic zone
The shallow coastal water that has abundant living organisms is called the "shoreline" or "intertidal zone." This area is home to a variety of marine life, including algae, mollusks, crustaceans, and fish.
Continental Shelf

There are more single called organisms than milticelled.
The presence of stromatolites declined significantly during the Late Proterozoic and Phanerozoic Eon due to increased predation by grazing organisms and changes in environmental conditions that made it more challenging for them to thrive.
A shallow area may be called a "ford" (the verb to fordis "to cross at a shallow point").

Shallow parts of the sea or ocean are called shoals or shallows. They are areas where the water depth is relatively shallow, making them potentially hazardous for navigation.
A shallow place in a river is called a ford if it is used as a place to wade across to the other side. A shallow place can also be called a sandbar if the water does not cover all of the sand in a river or stream.
A shallow part of water that you can wade through is typically called a "wading pool" or "wading area." These areas are often found in natural settings like rivers, lakes, or coastal environments, where the water is shallow enough for people to walk in comfortably without swimming. Wading areas are popular for recreational activities, especially for families with young children.
The continental shelf typically has the most shallow water on the ocean floor. This is the submerged edge of a continent that extends from the shoreline to a steeper drop-off point called the continental slope. The shallow waters of the continental shelf are important for marine life and are commonly where coastal communities are located.
