A coral reef is like a busy underwater city. Thousands of plants and animals live, eat, hide and grow there together.
Let's explore who calls the reef home! Tap Next to begin. 👉
Coral looks like a colourful rock or plant, but it is made of tiny living animals called polyps. They build a hard stone home, and over many years that becomes a reef.
Quick check: Tap each thing — is it living or non-living?
Tap each creature to discover something cool about it!
Every animal needs food. In the reef, energy passes along a food chain. Drag the pictures to build it in the right order — from tiny to big.
The reef has lots of nooks and cracks. Small animals hide there to stay safe from bigger ones. Tap the reef to help the little fish find a safe spot!
Reefs are easily hurt by rubbish, dirty water and water that gets too warm. When coral gets too hot it turns white — that is called bleaching.
Tap the kind choices that keep reefs happy. Tap the harmful ones to learn why!
