Fun Facts


  • Known as “rainforests of the sea,” coral reefs cover less than 1% of the ocean but are home to almost 25% of all known marine species!


  • Corals are in fact animals, not plants.


  • Coral reefs are naturally colourful because of algae, which lives inside of the coral, providing them with food.

The Great Barrier Reef


The Great Barrier Reef is the largest reef in the world. It can be found off the North East coast of Australia.

The Great Barrier Reef is larger than the entire country of Italy put together In fact, it is so big that astronauts can see the Great Barrier Reef from the moon. To give you an ideas of size, it spans about 70 million football fields!

Over 1500 kinds of fish live in the Great Barrier reef. The smallest fish is called the Stout Infant Fish which is only 7 millimetres long, and the biggest is the whale shark which can grow up to 12 metres long!

Fish on the Reef


The stripes and patterns on an angelfish act like a human fingerprint which makes each one unique.


Butterfly Fish:

The bodies of Butterfly Fish are very thin, which help them navigate through smaller passages.

Cardinal Fish:

Cardinal Fish are nocturnal and bury themselves within gaps in coral or caves during the daylight hours.



Over 160 species of shark live in the Great Barrier Reef.



Gobies live at the bottom levels of the reef and travel either alone or in small groups to avoid predators.



Clownfish live in shallow waters, making them easy to spot when you are snorkelling.
