The Great Barrier Reef is the home of the world’s largest coral reef. On the other hand, it lost more than half of its corals since 1998 due to some factors such as climate change and pollution. Amidst this damage of the Australia’s one of the amazing natural gifts, is a “blue hole” with full of surprising corals.
The massive “blue hole” is found by a marine biologist Johnny Gaskell. He first saw the blue hole on Google maps. Then, he went to confirm its existence together with a team.
Gaskell said that what they found inside the hidden lagoon was hard to believe, considering there was a Category 4 cyclone went straight over the top of it about five months ago.
He estimated the blue hole to be about 50 to 65 feet deep. Gaskell and his team are the first ones to dive inside the hole.
