Sharks primarily rely on a method called buccal pumping to move water over their gills, which involves actively closing their mouths and expanding their gill chambers to draw in water. Some species can also use ram ventilation, where they swim with their mouths open, allowing water to flow over their gills naturally. While sharks cannot "pump" water in the same way that some other fish do, they have adapted these methods to ensure adequate oxygen intake.
What else can I help you with?
Do sharks need to come for oxygen often?
Sharks do not need to come up for air - they are fish with gills.
Why do sharks die if they don't move?
Some sharks would drown but other sharks can pump water over their gills so they don`t need to swim. Some sharks lie in wait for their prey to come to them.
How do shark reproduction differ from fish reproduction?
Sharks can't pump water over thier gills only fish do.
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.
Why do most sharks have to swim all day or they will die?
Sharks do not have the ability to pump water across their gills, therefore they need to continue swimming to move water across their gills so they can breath
What shark can stop swimming and live?
Only some sharks are required to swim at all times. This is because the swimming motion helps water flow through its gills which enable it to breath. Other sharks have the ability to pump water through the gills without swimming.
Do sharks need to come up for air?
Sharks need to breathe, but they don't breathe air. They use their gills to "pull"oxygen from the sea water. They need to keep moving and breathing or they will die. Go to http:en.wikipedia.org and go to sharks. It's a free encyclopedia you can use for anything. Have fun I love sharks!!! Actually sharks don't use their gills to pull in oxygen, sharks' gills cannot take in water (which has oxygen in it) without either being in motion, or resting in a current. When the water flows over the gill slits blood in the gill filaments absorbs oxygen from the water being pumped over them, which is then carried to the muscles and organs in the rest of its body. Shark's gills are not covered. There is a spiracle, which is a modified slit, just behind the eye.
Do sharks sleep standing still?
The majority of sharks cannot sleep inanimately as they lack special gills that keep the water moving through them so that they can breathe. As always, there are exceptions, one of which is the nurse shark.
Why are cartilaginous fish such as sharks constantly moving?
If sharks did not move then they would die, when they move its like they are breathing, I know we dont do it but they are sharks ya know xD
Does a fish drown if you pull it backwards in the water?
Sharks cannot swim backwards. Unlike the fins of telelosts (bony fish), sharks' pectoral fins do not bend upwards, and so they are unable to back up. Sharks are also unable to stop swimming suddenly.
Why do sharks swim with their mouth open?
Many fish swim with their mouths open. They swim with their mouths open because the water goes into their mouths and out their gills, which is how they breathe.
What do fish pump water through?
their gills
