Most fish exchange gases using gills on either side of the pharynx (throat). Gills are tissues which consist of cloth and fabric structures called filaments. These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia.[1][2]Each filament contains a capillary network that provides a large surface area for exchanging oxygen andcarbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causing countercurrent exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx. Some fish, like sharks and lampreys, possess multiple gill openings. However, bony fish have a single gill opening on each side. This opening is hidden beneath a protective bony cover called an operculum.

How do sharks breathe underwater?
Using gills because sharks are fishes and if look closely on animal planet-sharks you will see that there are like cuts on the left or right of their head,well that is gills and sharks uses it to breathe it takes in oxygen and gives out carbon dioxide----------------------------------------------------------------------Sharks "breathe" by using their gills. Water passes through the mouth and out the gill slits. Oxygen is exchanged through the tissues lining the gills.Unlike other fish SOME SPECIES of shark cannot pump water through their gills by opening and closing their mouths, they have to keep moving to make the water flow. In this way they are like ram jets. For a shark it is "Swim or die!"However, OTHER SPECIES of sharks can pump water over their gills when at rest and do not need to keep swimming. These species can be seen sleeping on the seabed around tropical reefs.Gills.sharks breath through there gills. if you look up a picture of a shark with its mouth open yiou can see the gills at the side of the sharks mouth.hope i helped youIt's a fish.. it has Gills.
