What are coral reefs?

Coral reefs are like underwater cities built by tiny sea creatures called corals.

Corals are like little builders that live in the ocean. They team up with other tiny helpers, tiny algae, almost like green plants, to make strong homes for themselves and many other sea animals.

Imagine you're building a big treehouse with your friends. Each friend adds one small piece of wood or rope. Over time, all those little pieces become a huge, amazing treehouse. That's kind of how coral reefs grow, each coral and its helpers add tiny parts to the reef, making it bigger and stronger over many years.

A coral reef is like a busy neighborhood full of different animals. Fish swim around, crabs hide in the rocks, and sea turtles glide by. Some even use the reef as a place to lay their eggs or raise their babies, just like how you might have your favorite spot at school.

Coral reefs are important because they give food and shelter to thousands of sea creatures, making the ocean more lively and colorful.
