Sharks typically have 5 to 7 pairs of gill slits located on the sides of their bodies. These slits are used for obtaining oxygen from the water to breathe.
Sharks do not have lungs, but have between five and seven gill openings.

Gill slits in sharks and rays help to funnel water into the gills, which empty into the pharynx and eventually the lungs.
