1. The Great Barrier Reef is considered the largest living structure on Earth.
It's known for it's incredible size and amazing biodiversity. Home to hundreds of species of coral, which in turn are home to thousands of species of fish, the Great Barrier Reef is simply amazing!
2. What compound does coral extract from the ocean to make solid tentacles?
To make solid tentacles, coral extracts the compound calcium carbonate. Tentacles aid in feeding habits and protection.
3. How does red algae impact the structure of coral?
Red algae acts like pink glue, cementing bits of sand, shells, and coral together with calcium carbonate, and forming them into coral reefs, building coral on top of coral.
4. What year did the Great barrier Reef become a national park?
The Great Barrier Reef became a national park in the year 1975. However, even though it is preserved, that doesn't mean it is protected from all dangers. Many problems, including climate change and fishing, are still hurting the reef and are hazardous to its inhabitants.
5. What percentage of the reef is protected from fishing?
Only about 33% of the entire Great Barrier Reef is protected from fishing.
6. How old do scientists believe the CURRENT reef is? The ANCIENT reef?
Studies have shown that there are two reefs in the Great Barrier Reef, one on top of the other. Scientists believe the current reef is about 20,000 years old, but the ancient coral is half a million years old!
The Great Barrier Reef is one of the most intricate, bio-diverse, and beautiful ecosystems on our planet. However, it is also very old and very fragile. If we want it to be around to show our grandchildren, we have to keep it as healthy and protected as possible.
