Ineed on finding the physical features, movement of water, salinity of water, plants, and animals of the estuary, freshwater, marine biomes.

Mangrove trees and blue crabs are some of the estuarine species that have adapted to unique environmental conditions. In almost all estuaries the salinity of the water changes constantly over the tidal cycle. To survive in these conditions, plants and animals living in estuaries must be able to respond quickly to drastic changes in salinity.

This might help
