Estuaries serve as critical habitats for many marine species, providing spawning grounds and nurseries.
They act as natural filters, improving water quality by trapping pollutants and sediments.
Estuaries are highly productive ecosystems due to nutrient-rich waters from both terrestrial and marine sources.
Tidal action in estuaries causes constant mixing of fresh and saltwater, creating unique brackish conditions.
Human activities such as pollution, overfishing, and land development pose significant threats to estuary health.
