Facts

The reef is called the 'Barrier' Reef because it is an outer reef, situated along the Australian continental shelf with the channel between the coastline and the reef reaching a depth of about 60m. The other type of reef is a 'Fringe' reef, which is situated along the coastline of land and islands.

The coral on the reef dates back to around 18 million years old, and is thought to be about 500 metres in some places. Coral is made by Polyps which are marine animals from the Cindaria family. When the Polyps die, their skeletons turn white (which is how you know if coral is alive or dead) and then more Polyps grow on top of them.

What activities do people do in the Great Barrier Reef?

• some activities are feeding the fish the sharks and many more animals.

• this activity needs a lot of training for the dolphin because you have to make the dolphin jump throw a hoop when it does that right you have to give it a treat.
