Some of the oldest sharks did not need to constantly swim to take in oxygen. Instead, they used a method called buccal pumping to pass water over their gills, a method which many bottom dwelling sharks today still utilize. However, as sharks evolved to become more active, the method of buccal pumping became secondary and ram ventilation evolved as a more energy efficient way of breathing while swimming. As sharks are moving, water passes over the gills and blood vessels forming a capillary network extract the oxygen from the seawater through diffusion. After this exchange, water is expelled from the gills, and the process is repeated over and over. The majority of sharks have five gill slits, but a few special species have six or seven gill slits. {📷: @matthew_bernanke} . . . . . #shark #sharks #fish #fishing #miami #florida #science #sharkresearch #research #ocean #saltlife #water #conservation #nature #wildlife #nofilter #ig #sharkweek #instalike #instalove #photooftheday #picoftheday #uwphoto #reef #fishing #gills #swimming #sharksneedlove #summerday
