The coral reefs are made up of tiny living organisms called coral polups.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.
