Coral reefs in India are one of the most ancient and dynamic ecosystems of India. The coral reefs not only provide a sanctuary to a myriad of marine life but also play a key role in protecting the coastline from erosion. India has about 7517 km of coastline including islands but mainland coast is 6100 km.[citation needed]
The Coral reefs in India are mainly restricted to the Andaman and Nicobar Islands, Gulf of Mannar, Gulf of Kutch, Palk Strait and the Lakshadweep islands. All of these reefs are Fringing reefs, except Lakshadweep which are Atolls. There are Patchy corals present along the inter-tidal areas of the central west coast like the intertidal regions of Ratnagiri, Gaveshani Bank etc. The Hermatypic corals are also present along the sea shore from Kollam in Kerala to Enayam Puthenthurai in Tamil Nadu.[1]
