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.
crucible, Crucibles are generally as deep as they are high and crucibles imply that the item will be heated. I think the poster is looking for: Petri dish
A shallow area may be called a "ford" (the verb to fordis "to cross at a shallow point").
a small, shallow dish
An underwater extension of a coastal plain is called a continental shelf. This submerged area extends from the coastline to the shelf break, where the seafloor descends more steeply into the ocean depths. Continental shelves are typically characterized by shallow waters and are rich in marine life, making them important for fishing and biodiversity.
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 area of ponds and lakes near the shore is called the littoral zone. This region is characterized by its proximity to the shoreline, where sunlight penetrates, allowing aquatic plants to thrive. The littoral zone is crucial for the ecosystem as it provides habitat for various organisms and supports biodiversity.
