The deepest that a human being has dived without using a SCUBA tank is 214 meters. That is a long way down. Using SCUBA, Nuna Gomes descended to 318.25 meters.
That is still nothing compared to aquatic animals. A sperm whale can descend to 3 kilometers and remain submerged for 90 minutes. In order to cope with the pressure at such great depths, the sperm whale’s rib cage is flexible allowing its lungs to collapse. They also have a higher number of oxygen carrying red blood cells to cope.
The graphic to the right shows how far various animals can dive. It does not include the Trieste, a bathysphere that went to the bottom of the Mariana Trench at 10.9 kilometers. It also does not include the flounder or shrimp that live at that depth.
Pearl Divers dive without external oxygen sources in search of oysters containing pearls. How far can other creatures dive in their search for adventure or food? This graphic shows you how deep certain animals dive.
