How do plants and animals survive in estuaries?

How do animals in estuaries change their behavior?
Unlike plants, which typically live their whole lives rooted to one spot, many animals that live in estuaries must change their behavior according to the surrounding waters’ salinity in order to survive. Oysters and blue crabs are good examples of animals that do this.
