Fauna in the brackish environment
The areas where river waters flow into the sea are the environment of passage from freshwater to salty water, an environment that, due to sudden daily and seasonal changes in salinity and temperature, can only be inhabited by organisms that are specialised enough to tolerate such peculiar conditions. Because of such a difficult environment, the fauna and flora of brackish waters include quite few species. These few species are however plentiful because of the huge amount of nutrients coming from the rivers. In addition, such migrant species as eels and salmon can easily penetrate through the river mouths.
