📖 Read the story
Many people think corals are plants, but they are actually small sea animals. They live in large groups and build beautiful underwater homes called reefs. The most famous one is the Great Barrier Reef in Australia. Corals have tiny arms called tentacles. At night, they use these arms to catch food. They also live together with very small plants called algae. These plants make food from sunlight and share it with the corals. In return, the corals give them a safe place to live. Coral reefs are very important because many different fish live there. They are like busy cities under the sea. Next time you see a picture of a colorful coral reef, remember that it is a home for millions of active sea animals!
