The big blue hole is a karst funnel in The Atlantic Ocean, whose depth is 124 meters, and diameter – about 300 meters. The world has learned about this unique natural phenomenon in 1972, when the famous French Researcher Jacques-Yves Cousteau. He and his colleagues determined that the oxygen concentration at the very bottom of the funnel is so low that no complicated life can exist here.
Today the study of the Big Blue Hole is done by Fabien Cousteau, being the grandson of the legendary scientist, and the British billionaire Richard Branson They made their first dive in December 2018. years and then immediately faced with a mystery. Researchers found at the bottom strange chains of tracks that they could not find at first rational explanation. Busho jr and branson were very intrigued by their find, because they knew that complex organisms are not able to live in these conditions, at least so claimed the scientific team of Jacques-Yves Cousteau.

It turns out that the bottom of the karst funnel is, in fact, a cemetery shellfish. Once in an oxygen-free environment, gastropods begin gasping for breath and trying to climb up, but without success, and die from suffocation. Surprisingly, the divers did not immediately knit prints in the sand with scattered shells along the bottom that at first they took for the remnants of life from the upper layers of a blue hole …
