- rocky reefs.
- wave built bars in estuary mouths.
- deep estuarine channels where swift tidal currents flow.
- shallow open salt water and fresh water.
- river deltas.

Why estuaries is the most productive ecosystem?
Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
What kinds of plants and animals live in estuaries?
These habitats can include oyster reefs, coral reefs, rocky shores, submerged aquatic vegetation, marshes, and mangroves. There are also different animals that live in each of these different habitats. Fish, shellfish, and migratory birds are just a few of the animals that can live in an estuary.
