The estuarine communities are usually composed of endemic species and movable species with come in form the sea besides some species from freshwater.

Good nursery grounds for many fishes, plankton and organisms.

These are river delta estuaries present at the mouth of large river, i.e. Nile River.
The estuarine communities are usually composed of endemic species and movable species with come in form the sea besides some species from freshwater. But most of the estuarine Biota is of marine origin. In addition to this, estuaries serve as very good nursery grounds for many fishes, plankton and organisms.

The coastal zones of warm tropical and sub- tropical oceans often contain coral reefs.

Extending inland from the estuaries are coastal wetlands. In temperate coastal areas coastal wetlands usually consists of a mix of boys, lagoons, and salt marshes where mangroves trees are the dominant vegetation in tropical areas. The coastal zones of warm tropical and sub- tropical oceans often contain coral reefs.

Estuaries and coastal wetland areas provide many species with a number of vital services.

They supply food and serve as spawning and nursery grounds for many species of marine fish and shellfish. They are feeding, nesting and rearing sites for millions of birds and waterfowl.
In addition, estuaries and coastal wetlands and the sand dunes a barrier beaches help to protect coastal areas by absorbing waves caused by violent storms and hurricanes and serving as giant sponges to absorb flood waters. but coastal wetland are degraded by human activities such as garbage dumps, sites for urban industrial development and tourism.

The coral reefs are highly productive and are restrictive to tropical shallow waters of the sea

The open sea and wetland include the continental shelf, estuarine continental slopes and exclusive economic zone of India. The coral reefs are highly productive and are restrictive to tropical shallow waters of the sea. One of the unique feature of the ecosystem is the sea-grasses which play a vital role in maintaining the biodiversity and productivity of the ecosystem.
