Yes sharks have gills they are five slits located just in front of their pectoral fins.

How do shark gills work. Sharks have 5 7 pairs of gill slits located on the sides of their heads. Once the shark allows water to enter their mouth it goes through the pharynx over the gills and finally leaves through the actual gill slits. Oxygenated water is passed over the gills which have a rich near surface blood supply and gases are exchanged between the blood and the water.

The gills are feathery and have a large surface area so that there is enough gas exchange to keep the fish supplied with the oxygen it needs. Located on the side of a sharks head are five to seven gill slits. However sharks do not have this covering.

Actually this tale isnt true for all shark species. Larger more active sharks tend to hunt in the middle and upper depths of the ocean while many smaller sharks stay near the ocean bottom. In order for gas exchange to occur correctly water has to consistently flow over the gill slits.

Some sharks swim long distances every day while others live a relatively sedentary life sticking to a small area. They live all over the world and swim at every ocean depth. Water must continually flow across these slits in order for the shark to breathe.

Like other fish sharks breathe through their gills which are respiratory organs akin to. Whale shark gills are similar in structure to other fish gills. Sharks must constantly swim or theyll die right.

Without gills a shark would not be able to breathe underwater. Although a whale shark can come to the surface it does not need to do so in order. In most other fish species these gills are covered by the operculum which acts as a lid over the gill.

Unlike bony fish they do not have gill covers. Sharks are also very diverse in their habits and habitats. There are usually between five and seven gill arches each bearing one gill slit.

Sharks are fish and like other species of fish use gills to breathe rather than lungs. This can be accomplished by the sharks swimming by it standing still in a current or by it fanning water across the gills with its fins this is done by the nurse shark.
