The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometers over an area of approximately 344,400 square kilometers, as big as a city. Located in the Coral Sea, off the coast of Queensland, Australia, the Great Barrier Reef can even be seen from outer space!
These coral reefs are made up of tiny living organisms called coral polyps. Coral polyps take calcium carbonate from the ocean water to build their hard skeletons, which form the base of the reef. Millions of polyps working together over millions of years have created this vast underwater structure.
The Great Barrier Reef is a haven for a mind-boggling variety of marine life. Over 1,500 species of fish, 411 types of hard coral, 134 species of sharks and rays, and six of the world's seven species of marine turtles call the reef home. This incredible biodiversity makes the Great Barrier Reef a UNESCO World Heritage Site.
Sadly, the Great Barrier Reef faces threats from pollution, climate change, and overfishing. Rising water temperatures cause coral bleaching, which is when coral loses its vibrant colors and dies. Protecting this natural wonder is crucial for the health of our oceans and the amazing creatures that live there.
