The Belize Blue Hole, located on Lighthouse Reef at the edge of the Grand Bahama Bank's submarine plateau, boasts a circular opening surrounded by two coral reefs. It's a renowned diving destination, renowned for its sponges, barracudas, corals, angelfish, and the sharks that frequently patrol the hole. The diverse shark population makes it a challenging spot for many adventurous divers.
Looking down from above, a circular pool of deep blue water, like the pupil of the ocean, appears beneath the tranquil surface of the ocean. This phenomenon, seen from an unfathomable depth, is profound, mysterious, and eerie. This phenomenon is known as a blue hole. While there are many blue holes of varying sizes and shapes scattered throughout the world's oceans, the most famous is the Belize Blue Hole.
