Polyps are nothing but sea anemones to which they are related. Coral polyps secret hard carbonate exoskeleton which supports and protects their bodies. Warm and shallow waters are preferable for growth of coral reefs

Coral reefs are rich in biodiversity and so they are called tropical rainforest of the sea. They are the most diverse ecosystem of the earth, they occupy just 0.1% of ocean’s surface and hey are home to 25% marine species including crustaceans, fish and mollusks.

They provide variety of ecosystem services like tourism and fisheries. And corals are fragile ecosystem where rise in temperature can destroy them and change in salinity will also have adverse impacts on them. So climate change is the new threat faced by these fragile species
