Like other fishes, sharks breathe by extracting oxygen when seawater pass through their gills.

Shark gills are just behind the shark head, and they do not have covers like most fish.

The water passes through the gills when sharks are swimming making impossible for most of them to stay still otherwise they would drown.

This process is called ram ventilation.
