Answer:
Coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Mudflats or mud flats, also known as tidal flats, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers.
salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides.
rocky shore is an intertidal area of seacoasts where solid rock predominates.
Animals living in it
Coral Reefs- Fish, corals, lobsters, clams, seahorses, sponges, and sea turtles are only a few of the thousands of creatures that rely on reefs for their survival.
Mud flats- clams, mussels, snails, and crabs. When the mudflats are exposed at low tide, hun- dreds of shorebirds and waterbirds of varying sizes appear.
Salt Marsh- Composed of fine silts and clays, mud flats harbor burrowing creatures including clams, mussels, oysters, fiddler crabs, sand shrimp, and bloodworms. Salt marshes are salty because they are flooded by seawater every day. They are marshy because their ground is composed of peat.
Rocky shore- Common rocky shore groups include mussels, barnacles, limpets, sea anemones, and predatory sea stars, each with a different ability to avoid predation or live outside of the water.
