How Does A Shark Breathe?
As other fishes, sharks breathe by extracting oxygen when seawater pass through their gills. Shark gills are just behind shark head and they are not specially covered like in most fish. Water pass thorough their gills while sharks are swimming making impossible for most of them to stay still as otherwise they would drown. This process is called ram ventilation.
