Estuaries are also important homes for fishes, snails, crabs, clams, and baby animals called larvae.
We call these habitats wetlands, because the soil of the marsh and the bordering edges of the estuary are frequently influenced by tides from the ocean and water flowing from the land. Rises in water levels make the land wet. But, as levels change, constantly rising and falling, the amount of wetness changes. Wetlands located along the coasts are called coastal wetlands. If you live in Texas, the coast is along the Gulf of Mexico.
