coral reef
Definition
Coral reefs are like underwater forests. They are made up of tiny animals called coral polyps. Coral polyps live in colonies, and they build their homes out of calcium carbonate. This makes the coral reefs very strong and hard. Coral reefs are home to many different kinds of animals, including fish, shrimp, and crabs. They are also a very important part of the ocean ecosystem.

This is because the first corals to be known to Europeans were the red corals of the Mediterranean Sea, which are small and pebble-like.
