Why Coral Reefs are important?

Coral Reefs are one of the most biologically diverse marine ecosystems on the earth.

These are found in the shallow tropical areas where the seawater is clean, clear, and warm and spreads in a large area having rich species diversity.

Coral Reefs are important due to the following reasons.

1. Ecologically, coral reefs are important because they are the counterpart to the tropical rain forest in terms of biological productivity in the Ocean and species diversity.
2. Coral Reefs are natural protective barriers against erosion and storm surge.
3. They provide habitat for a large variety of plants and animals.
4. Coral reefs provide an accurate long-term record of climate change by helping in determining the climate variability in remote tropical oceans and thus are climatologically important.
5. Coral Reefs provide substrate for mangroves.
6. They help in the formation of associated eco-systems which allow the formation of essential habitats, fisheries, and livelihoods.

Where are Coral Reefs found in India?


Coral Reefs in India can be found in the following regions –

Gujarat – Gulf of Mannar and Gulf of Kutch

Andaman and Nicobar Islands

Lakshadweep islands

Maharashtra – Malvan and Angria Bank

Karnataka – Nertrani Islands

Palk Bay ( Palk Bay (Palk strait) is a shallow and confined sea falling between Tamil Nadu in India and Srilanka).

What are corals and Coral Reefs?

Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically live in compact colonies of many identical individual polyps.

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.

World Wide distribution of coral reefs

Tropics of Cancer and Capricorn, the Pacific Ocean, the Indian Ocean, the Caribbean Sea, the Red Sea, and the Persian Gulf contains most of the Coral Reefs in the world.

Corals are also found farther from the equator in places where warm currents flow out of the tropics, such as in Florida and southern Japan.
