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.

∙ 10y agoMany sharks are able to breathe by pumping water over their gills, just as other fish do. Some sharks must be moving in order to breathe because they have lost this ability to pump water over their gills. They move even when they are sleeping in order to keep water passing through their mouths and over their gills. These sharks are called 'obligate ram ventilators'. They must (obligate) push themselves through the water (ram) in order to breathe (ventilate).

∙ 11y agoSharks are fish and get their air/oxygen from the water. Some sharks, like the Great White, stick their heads above water to have a look around (as does the mammal Killer whale), but, sharks do not need to come up for air. Sharks would die of suffocation if their gills were out of the water for a long period of time.

∙ 13y agoALL sharks have to swim to breathe, so that water can pass through their gills. There are some sharks in Mexico that can" sleep", while resting on the ocean bottom, and do not have to swim to breathe. I saw a TV special YEARS ago regarding "Sleeping Nurse Sharks" in Florida. They had found an underground cave area that had a rather strong current, so they would wedge themselves into a nook and stop moving. In this manner, water still passed through their gills so that they could breathe.

∙ 12y agoNo, sharks have gills and thus can not breath out of water.
(also while IN water they need to keep there tails moving to breath)
The highlighted above forementioned info is false, in fact some species of shark have evolved to adapt to their current marine life.
Such as the Epaulette shark
Hemiscyllium ocellatum
The Epaulette Shark which is a slender species that has a large black
ocellus (eye-like spot with a marginal ring) above the pectoral fin
and widely spaced black spots on the body, can survive
in shallow water on coral reef. Epaulette
sharks can survive out of water for a few hours. Its a non-dangerous
species. Some can and do survive out of water for quite some time.

∙ 12y agoOnly 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.

∙ 10y agoSharks don't sleep. They need to move continuously, because otherwise their gills would fill with water and they would suffocate. That's why beached sharks die almost instantly.

Is it true that a dolphin can beat up a shark?
No, this is a fallacy. Although dolphins and sharks do not seek each other to attack, they appear to have a mutual respect. Normally, a shark will only attack a lone dolphin, a sick dolphin or a calf that strays from its mother. In Port Phillip Bay, the large male dolphins that usually live outside the bay come inside at the beginning of October, which is the same time that the bronze whaler sharks come into the bay to mate and give birth. Male dolphins form a guard around the females and young to protect them during this time. Sharks usually keep their distance from the dolphins.
Do sharks need to come for oxygen often?
Sharks do not need to come up for air - they are fish with gills.
How does sharks get there air?
they have gills, they can breathe underwater for up to 4 months at a time without coming up for air.
How far can whales go underwater?
it can go up to 3 miles down but have to come back up for air because whales are mammals and need to come up for air. mammals need air and a whale is a mammal. a whale has hairs and is a warm blooded creature.
Why aren't whales fish?
They need to come up for air, unlike fish.
Do turtles need to come up for air?
Yes manatees are mammals which means they breathe air
How are sharks hurt?
when people capture sharks they cut off their fins and then release them back into the water for dead because sharks can't swim without fins so they sink to the bottom of the ocean to drown because they have to come up for some air sometime but can't without fins

Jellyfish live under the water and get their oxygen from the water itself therefore they do not nee to come to the surface to get air.
How did you know a whale is not a fish?

Do Asian shore crabs need to come up on land for air?
Only if you think so
Why do tadpoles come up for air?

Could you have 2 albino rainbow sharks in a fish bowl?
You could as long as they are tiny, but they need a better tank than that, they need filtration and air in the water, very few fish can live in a bowl for very long, the ammonia builds up or the air runs out.
Do seahorses come up for air?
No they do not
