Taam Ja' Blue Hole deeper than expected
Scientists found that a big underwater hole called Taam Ja' Blue Hole is much deeper than they thought.
It's 1,380 feet deep, which makes it the deepest blue hole in the world.
They used a special tool to measure how deep it is and found different layers of water.
One special layer at 1,312 feet has similar conditions to the Caribbean Sea.
Scientists think there might be hidden tunnels and caves connecting this hole to the ocean.
They haven't reached the bottom yet, so there's still more to explore!
Taam Ja' Blue Hole is 1,380 feet deep, surpassing previous estimates of 900 feet.
It is now recognized as the deepest blue hole on Earth, deeper than the Sansha Yongle Blue Hole by 390 feet.
Scientists detected a unique water layer at 1,312 feet with conditions similar to the Caribbean Sea and coastal reef lagoons.
The blue hole's bottom has not yet been reached, indicating further exploration is needed.
A hidden network of tunnels and caves may connect the blue hole to the ocean.
