How do shark reproduction differ from fish reproduction?
Sharks can't pump water over thier gills only fish do.
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.
What do fish pump water through?
their gills
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 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.
Why goldfish dead without oxygen pump?
Yes, that's why they have their gills they take in the water and breath in the oxygen, through the water, and let go of the water through their gills
How do sharks live?
A Shark lives mainly in the ocean constantly swimming. It's bladder does not have an air bubble like other fish, so if it would stop swimming it would sink to the bottom of the ocean and die.SuperSlasherSome sharks ca pump water over their gills so they won`t die. The bull and Greenland sharks can live in freshwater.
What are the main parts of a shark's respiratory system?
Quite simple. I have studied sharks for 5 years. Im only ten. They dont have lungs. They have to keep moving to force water through their gills. Other sharks like the White Tip Reef Shark can suck it in. So they force it through their gills and the gills extract the water molecules and let the oxygen molecules that have evaporated in the water flow down to the heart. The heart pumps them through a network of veins to the body cells The body cells turn the nutrients into energy. When the body cells do this the make a waste gas called carbon dioxide (c02) The heart can pump two ways so it pumps up the c02 back to the gills that extract them back into the water. It has to do that each breath.
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.
Can sharks pump water over their gills?
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.
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 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.
