Coral reefs might look like plants but they are made up of many tiny creatures. The Great Barrier Reef, in Australia, is the only living thing that can be seen from space

Unscramble these letters to find the names of creatures who life on the reef:

Ancient stone

A coral reef is like a big rock in the ocean. This rock is really made up of millions of tiny little creatures. These creatures are called coral polyps.

Hard and soft

There are two kinds of coral - hard and soft. They both start off as tiny worms that land on the reef. The hard coral makes a home out of calcium. This is the same stuff that makes your bones and teeth. Those polyps all join together like Leggo blocks to make the reef. The soft coral is more like a plant.

Deadly stingers

Coral eats tiny animals that float in the sea. It catches the tiny animal with its tentacles and could sting it before pulling it into its mouth.

Reef life

Many different creatures live on or near a reef. Usually their colours are very bright. This is because the coral itself is bright.

Many colours

Coral's colour comes from the algae that live in its body. These algae can use the sun to make food. They make enough food from themselves and the coral.

In the movies

The most famous reef movie is Finding Nemo, about a clownfish that is caught by humans and tries to find his way home.
