The Sundarbans, being a large mangrove area and delta region, are characterized by high sediment loads, variable salinity (brackish water influenced by freshwater rivers), and often turbid water conditions. These conditions are generally not suitable for the development and survival of extensive coral reefs.
Corals thrive in clear, warm, shallow marine waters with stable salinity and sufficient sunlight for the symbiotic algae (zooxanthellae) living within their tissues. High sedimentation and variable salinity negatively impact coral health.
