VIDEO: MARINE BIOLOGIST CAPTURES STUNNING FOOTAGE OF THE GREAT BARRIER REEF!

Turns out there is a massive blue hole in the Great Barrier Reef in Australia. The reef already offers plenty of wonders, but this blue hole is on a whole different level of cool. 

It was found by marine biologist Jonny Gaskell, who said he spotted the blue hole on Google Maps. He went on a quest to check it out with a team, despite it being far offshore, "further than our normal Reef trips."

"What we found inside was hard to believe, considering five months ago a Category 4 cyclone went straight over the top of it," Gaskell said in a statement. Gaskell and his team managed to capture the inside of the hidden lagoon, which looks like a fun adventure. 

Gaskell said himself and his team believe they are the first to dive this blue hole, which they won't reveal the location of publicly, preferring to keep it a secret. The lagoon walls act as a source of protection to the coral.

"It's not as deep as the famous Great Blue Hole in Belize but it is a really unique spot. At around 15 to 20 metres deep, there were huge Birdsnest Corals – Seriatopora – and super elongated Staghorn Corals – Acropora –, both of which were among the biggest and most delicate colonies I've ever seen," Gaskell said.

Since the discovery, Gaskell has located two other blue holes, roughly 200 kilometres offshore, and is working out logistics to travel there. There are also blue holes in the Cockatoo and Molar Reefs.

It's certainly a bright bit of news from the reef, which is still under serious threat from coral bleaching. Have a look at the video to see the beautiful hidden-gem of nature in the Great Barrier Reef
