Sunderbans is known for mangrove ecosystem and does not have coral reefs.

Other places mentioned i.e. Andaman and Nicobar, Gulf of Kachchh and Gulf of Mannar have coral reefs.

Coral reefs are absent near river mouths due to sedimentation, increased turbidity, fluctuating salinity, and nutrient loads carried by rivers. Sediments can smother reefs, high turbidity reduces light availability, fluctuating salinity stresses corals, and excessive nutrients can lead to harmful algal blooms. These factors create unfavorable conditions for coral growth and survival, explaining their absence near river mouths.
