Description: Fringing reefs are the most common type of coral reefs. They grow directly along the shoreline, extending outwards into the sea. These reefs are usually closely attached to the shore, forming a border along the coast.
Growth: They develop in shallow waters and are directly connected to the island or mainland, with no significant water body separating them from the land.
Barrier Reefs:
Description: Barrier reefs are separated from the shore by a body of water, known as a lagoon. They are typically farther from land compared to fringing reefs.
Growth: These reefs form parallel to the coastline but are separated by deeper and wider lagoons. They often encircle an island or a group of islands, providing a barrier between the open sea and the lagoon.
Atolls:
Description: Atolls are ring-shaped coral reefs, often surrounding a lagoon, and are usually located in the open sea.
Formation: They typically form when a volcanic island subsides below sea level, leaving a ring of growing corals that originally developed along the shoreline of the island.
Coral Reefs in India:
Gulf of Kutch: Located in the Arabian Sea, this area has coral reefs characterized by rich marine biodiversity.
Gulf of Mannar: Situated between India and Sri Lanka, these reefs are part of a large marine ecosystem with diverse coral species.
Andaman & Nicobar Islands: These islands in the Bay of Bengal are renowned for their vibrant coral reefs, which are among the most pristine in India.
Lakshadweep Islands: Situated off the coast of Kerala in the Arabian Sea, these islands are known for their spectacular atolls and diverse marine life.
Malvan: This region, located along the western coast of India, features fringing reefs with a variety of coral species.
