Blue HolesA blue hole is a submarine cave or underwater sinkhole. They are also called vertical caves. There are many different blue holes located around the world, from Belize and the Bahamas to the Red Sea. Blue holes are roughly circular, steep-walled depressions, and so named for the dramatic contrast between the dark blue, deep waters of their depths and the lighter blue of the shallows around them.

Their water circulation is poor, and they are commonly anoxic below a certain depth; this environment is unfavorable for most sea life, but nonetheless can support large numbers of bacteria. The deepest blue hole in the world—at 663 ft.—is Dean's Blue Hole, located in a bay west of Clarence Town on Long Island, Bahamas. Other blue holes are about half that depth at around 330–390 ft.
