Coral Reef is an underwater ecosystem formed by colonies of tiny marine invertebrates called coral polyps. These polyps live in symbiosis with microscopic algae, zooxanthellae, which give them energy and vibrant colors. Coral reefs provide food and shelter to a quarter of all marine life despite covering only about 1% of the ocean area. Coral reefs are considered the rainforests of the sea because of the rich biodiversity they support.
In this article, You will get to know about Coral reefs, How they formed, the List of coral reefs found in India, their types, and much more about them.

Coral Reefs in India
Here’s an overview table summarizing information about coral reefs in India:
| Coral Reefs | Location | Key Features | Threats |
|---|---|---|---|

| Lakshadweep | Off the southwestern coast of India | Atolls, Barrier reefs, Marine National Park | Coral bleaching, tourism impacts, pollution |
| Andaman and Nicobar Islands | Bay of Bengal and Andaman Sea | Rich biodiversity, Remote and pristine reefs | Coral bleaching, dynamite fishing, climate change |
| Palk Bay | Between southeastern India and Sri Lanka | Important fishing grounds, Shallow reefs | Overfishing, pollution, habitat destruction |
| Gulf of Kutch | Off the coast of Gujarat | Unique cold-water coral reefs | Industrial pollution, coastal development |
Meaning of Coral Reefs
Coral reefs are underwater ecosystems formed by colonies of tiny animals called coral polyps. These polyps secrete calcium carbonate to build hard skeletons, which accumulate over time, forming intricate structures known as coral reefs. Coral reefs are often found in shallow, warm, clear waters, particularly in tropical and subtropical regions.
These ecosystems are incredibly diverse and provide habitat and food for a wide range of marine life, including fish, crustaceans, mollusks, and sponges. Coral reefs also offer numerous benefits to humans, including coastal protection from storms and erosion, fisheries support, tourism revenue, and potential medical discoveries through the study of marine organisms.
Types of Coral Reefs in India
India has a variety of coral reef formations, each with unique characteristics and the types of coral reefs in India are as follows:
- Fringing reefs: These are the most common type in India. They grow directly along the coast, with a shallow lagoon separating them from the mainland.
- Fringing reefs are found in the Andaman and Nicobar Islands, the Gulf of Mannar, the Gulf of Kutch, and the Palk Strait.
- Barrier reef: India has only one major barrier reef, located along the west coast of the Andaman and Nicobar Islands.
- Unlike fringing reefs, barrier reefs run parallel to the shore at some distance, creating a deep lagoon in between.
- Atolls: These fascinating ring-shaped reefs encircle a central lagoon.
- India’s atolls are found in the Lakshadweep Islands, where chains of coral reefs have grown around submerged volcanic islands that have since eroded.
- Patchy reefs: These are smaller, isolated coral formations found scattered in areas with suitable conditions.
- Patchy reefs occur along the central west coast of India, in areas like Ratnagiri, Malvan, and Redi.
Highest Coral Reefs in India
The highest coral reefs in India are found in the Gulf of Mannar, located off the southeastern coast of Tamil Nadu. The Gulf of Mannar is known for its diverse marine ecosystem and is recognized as a Biosphere Reserve and Marine National Park. The coral reefs in this region are characterized by their rich biodiversity, including various species of corals, fish, crustaceans, and other marine organisms.
Laws protecting the Coral reefs of India
- The Environment Protection Act, 1986 (EPA): This broad act allows the government to declare protected areas and regulate activities that pollute or damage the environment. Coral reefs can potentially benefit from this by falling under protected areas.
- The Coastal Regulation Zone (CRZ) Notification of 1991: Issued under the EPA, this notification divides India’s coastline into different zones with varying restrictions on development activities. This helps regulate activities near coral reefs that could cause harm.
- The Wildlife Protection Act (WPA), 1972: This act offers protection to designated wildlife sanctuaries and national parks. Many coral reef areas in India are included in these protected zones.
- The Indian Forest Act (IFA), 1927: The Indian Forest Act (1927), the Forest Conservation Act (1980), the Indian Fisheries Act, and various state fisheries acts can also play a role in managing activities that might impact coral reefs.
