Located in the Bahamas, it is named as the blue hole because of its deep cavities arriving in circle shapes.
Divers reportedly have seen new species and creatures which is yet unknown. The hole has an estimated length of 14 km with chambers filled with stalagmites and stalactites. Here’s a picture of a diver deep into the Belize Blue Hole.

It’s believed that sea level may have been lower than 150 m as compared to what it is today and in time, water made the limestone worn out and then formed caves. After this, the sea level rose again while some collapsed and formed blue holes. This happened around 65000 years ago during the ice-age.
