Do sharks suffocate if they stop swimming?
So, while most sharks will be 100% fine if they stop swimming, a few iconic species such as great white sharks, whale sharks, hammerheads and mako sharks would suffocate without forward motion or a strong current flowing towards their mouths.
What shark can breathe on land?
The incredible epaulette shark is not only a perfectly capable swimmer, but it can also “walk” between coral heads at low tide, along the seafloor, and even on land when needed. For that reason, it is often called the “walking shark.”
Do sharks breathe air?
How Sharks Breathe. Sharks don’t have lungs, but they do have to breathe oxygen to survive. Instead of breathing air, though, sharks get oxygen from the water that surrounds them.
How long can a shark survive?
In 2016, scientists in Greenland discovered a 400-year old shark, evidence that some sharks can live for well over 100 years. It’s believed that Dogfish and Whale sharks species live for more than 100 years. But of course, each shark species has a different life expectancy.
Can sharks smell period blood?
A shark’s sense of smell is powerful – it allows them to find prey from hundreds of yards away. Menstrual blood in the water could be detected by a shark, just like any urine or other bodily fluids.
Do sharks fart?
We’ve all seen tiger sharks in aquariums just hanging there, unlike most sharks which would sink, well this is their secret! They let air out in the form of a fart when they want to lose buoyancy.
How many hours do sharks sleep?
Instead, they sleep when their instincts tell them to. However, as we’ve already learnt that sharks sleep is simply periods of rest compared to active periods, they actually go through many of these periods in a twenty-four hour period.
Is there one Megalodon left?
Megalodon is NOT alive today, it went extinct around 3.5 million years ago.
Did sharks exist before trees?
Fun fact of the day: Sharks are older than trees. The earliest species that we could classify as “tree,” the now-extinct Archaeopteris, lived around 350 million years ago, in forests where the Sahara desert is now.
Can a shark drown?
Is it possible for a shark to drown? Despite being ocean dwellers, most sharks need oxygen to breathe. They don’t have lungs but instead absorb oxygen from the water using their gills. If there’s not enough oxygen available in the water, sharks can’t breathe and can easily drown.
Do sharks drink water?
Sharks keep them in their body, which keeps them “salty”. Sharks take in small amounts of water through their gills (by osmosis – because they are slightly saltier than the sea) which means they don’t directly have to drink. Sharks also have a salt gland (in their rectum) to get rid of any excess salt they may have.
How do sharks give birth?
Ovoviviparity: Most sharks are ovoviviparous; they combine the first two methods. They produce eggs, but instead of hatching outside the body as in oviparity, the eggs are carried within the female for the gestation period. When the egg hatches, the shark pup continues developing inside the female until it’s born.
Do sharks go to sleep?
Whatever method they use to breathe, sharks are able to engage in periods of deep rest while still but do not fall asleep in the traditional sense. Lacking eyelids, their eyes remain perpetually open, and their pupils still monitor the motion of creatures swimming around them.
What are 3 interesting facts about sharks?
- Sharks do not have bones. …
- Most sharks have good eyesight. …
- Sharks have special electroreceptor organs. …
- Shark skin feels similar to sandpaper. …
- Sharks can go into a trance. …
- Sharks have been around a very long time. …
- Scientists age sharks by counting the rings on their vertebrae.
How long can a megalodon live?
It was 46 years old when it died. They estimate its length to have been 30 feet. Some megalodons are estimated to have been much larger―as long as 50 feet. Using the data from this study, together with previous research, the researchers concluded that the potential lifespan of megalodons was 88-100 years.
How do sharks sleep if they can’t stop swimming?
Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.
What happens if a shark stops moving?
Myth #1: Sharks Must Swim Constantly, or They Die
Some sharks must swim constantly in order to keep oxygen-rich water flowing over their gills, but others are able to pass water through their respiratory system by a pumping motion of their pharynx. This allows them to rest on the sea floor and still breathe.
Do sharks stop swimming to sleep?
Sharks can sleep, and often opt to keep their eyes open while they do, according to new research published in Biology Letters. Because some sharks must swim constantly to keep oxygen-rich water flowing over their gills, it has long been rumored that they don’t snooze at all.
How long can sharks hold their breath?
Death will follow between four and six minutes after that. Without oxygen, most large shark species will suffer a very similar fate. Hypoxia will rapidly cause brain damage, so while an oxygen-deprived shark may appear to be still alive, it will likely rapidly suffer irreversible damage in just a few minutes.

How Long Can a Shark Survive Out of Water?
When thinking about sharks, you might be interested to know how long can a shark survive out of water. After all, if you’ve seen the movie Jaws and remember the infamous scene where the great white shark comes almost entirely onto the boat for several minutes, you could wonder if this is possible in reality
We’re going to see that the large shark species most of us are familiar with cannot survive out of water for very long at all. In fact, while they may not die instantly, being out of the water for any length of time can cause death fairly quickly to large sharks.
All sharks are fish and get the oxygen they need to survive from the water they swim in. As soon as they are in the air, no shark can breathe. The shark species involved, its size, and the circumstances surrounding its removal from the water may determine how long it can tolerate being on land.
However, we will see that some fascinating smaller sharks have actually managed to adapt so they can spend time out of the water and not suffer any consequences.
Can Sharks Breathe Out of the Water?
No, sharks can’t breathe out of the water.
Sharks, like all other fishes, get the oxygen that they need from the seawater around them. Fish don’t have lungs as we do. Instead, water flows through their gills, which extract oxygen and pass it into the shark’s blood.
Without water, the shark’s gills cannot function, meaning that no oxygen would enter the bloodstream, and the shark would asphyxiated.
Reading Suggestion: Do Sharks Jump Out of the Water?
Some sharks, called active pelagic sharks, use a process called ram ventilation. Water is forced through their gills to continually provide oxygen as these sharks swim. It is said that if these obligate ram ventilation sharks stop moving, they cannot breathe and will die.
Some species move in a swimming and gliding pattern. While they may not be actively swimming the whole time, they are moving, so the effect of pushing oxygenated water through their gills is the same.
Well-known examples of ram ventilators include the great white (Carcharodon carcharias), bull (Carcharhinus leucas), thresher (Alopiidae), hammerhead (Sphyrnidae), tiger shark (Galeocerdo cuvier), and whale shark (Rhincodon typus).
Other species, called benthic sharks, will rest on the bottom for large amounts of time and so need a different method to push oxygenated seawater through their gills. These sharks have openings called spiracles which effectively pump water through the gills meaning that the shark doesn’t have to move.
Examples of sharks with spiracles include some reef sharks, zebra sharks (Stegostoma tigrinum), and Wobbegongs (Orectolobidae).
Finally, small sharks, like the spotted catshark (Scyliorhinus canicula), suck water through their mouths using a method called buccal pumping. Using their large cheek muscles can supply oxygenated water to their gills while they are stationary.
Why Can’t Sharks Breathe on Land?
Sharks cannot breathe on land because they have gills and not lungs. Our lungs have evolved to absorb gaseous oxygen and pass it into our blood for our bodies to use.
While a shark’s gills also absorb oxygen, they can only do so from oxygenated water. This means that without being surrounded by water, the shark cannot breathe and will eventually die.

How Long Can a Shark Live Without Water?
How long a shark could live out of water will depend on the species and its size. They may survive minutes or up to about an hour. As well as needing oxygen to survive, sharks have evolved to take advantage of the physical support that water gives them.
Unlike, for example, mammals, sharks don’t have skeletons with rib cages that maintain their body shape and protect their organs. Without being submerged, most large shark species including great white and tiger sharks will quickly suffer internal bleeding and crushed organs from the effects of gravity on land. So if they didn’t suffocate from lack of oxygen, they would probably die even if they were returned to the water seemingly alive.
Reading Suggestion: How Close To The Shore Do Sharks Come?
In addition, a shark out of the water is likely to struggle and flap to try and get itself free. This will not only use up valuable oxygen but will probably also further physically damage the shark.
If the gills remain wet, then some minimal oxygen exchange may take place to sustain the shark. However, this probably won’t be sufficient for the shark to function correctly, and as soon as the gills dry out, they won’t work at all.
The gills are also usually damaged when they are out of the water. The gills will often get stuck together, meaning that when the shark does get put back in the water, they may not function effectively.
Thankfully for the sharks involved, how long they can live without water has not been extensively researched. It could range from just a few minutes to several hours.
However, while the animal may not wholly pass away, time out of the water will likely cause internal damage, including brain damage from lack of oxygen, that could dramatically shorten its life.
How Long Can a Shark Live Without Oxygen?
If all oxygen is taken away from a shark, it will suffer brain damage and die pretty quickly. In a human, permanent brain damage occurs after about four minutes without oxygen. Death will follow between four and six minutes after that.
Without oxygen, most large shark species will suffer a very similar fate. Hypoxia will rapidly cause brain damage, so while an oxygen-deprived shark may appear to be still alive, it will likely rapidly suffer irreversible damage in just a few minutes.
How Long Can Sharks Stay Underwater?
Sharks can, and should, stay underwater for their whole lives! They have evolved to be underwater constantly.
Reading Suggestion: Can s Shark Drown?
You may have seen incredible photographs of great white sharks leaping out of the water. However, they are trying to catch prey such as sea lions at the surface. The shark is out of the water for less than a second, so it doesn’t suffer.
Should You Try To Save a Stranded Shark?
Some people ask how long can a shark survive out of water because they are wondering if it is worth trying to save a stranded shark.
While a stranded shark may suffer some damage from being out of the water, surely it will experience certain death if it is left on dry land.
While attempting to save a shark that has got stuck on land, the first thing to do is keep it wet. Rescuers will often pour buckets of seawater over the shark’s gills. While this may not give the shark all the oxygen it needs, keeping the gills wet could at least allow some to enter the animal’s blood.
Sharks out of the water will also quickly suffer from hypothermia in warm weather as the sun and temperature overheat their bodies. Pouring water on them may help to keep them cool.
Professional marine rescue teams exist in many locations, and if possible, it’s a good idea to call for their help. Even with the best intentions, the safety of people comes first, and extreme caution must be taken, particularly when dealing with large shark species.
If possible, the shark should be moved by the tail so that people are away from its mouth. You need to be aware that a stressed shark can flap with vast amounts of strength, so if possible, rescuers should use a rope to pull the animal to the water instead of manhandling it and risking injury.
Once in the water, ram breathing sharks may need pushing back and forth or even pulling from a boat to force water through their gills to recover significantly from lack of oxygen to be able to swim.
How Long Does It Take for a Shark To Suffocate Out of the Water?
Depending on the conditions, a shark could suffocate in just a few minutes. The animal will start to receive less oxygen from the moment it is out of the water. Even damp gills will only function at a small fraction of their usual efficiency.
Typically we can say that the larger the shark, the faster it will suffocate. Even if the gills are kept wet, the lack of fresh oxygenated water flowing through them and problems caused by gravity will suffocate a white or tiger shark very quickly.
How Long Can a Great White Shark Last Out of Water?
Great white sharks will quickly die out of the water. Lack of oxygen may cause the shark to suffocate in just a few minutes, or its weight may cause significant internal bleeding.
Reading Suggestion: Do Sharks Have Tongues?
Any great white shark out of the water will suffer injuries. However, it’s impossible to say how dramatic these will be or how long they will take to come into effect.
Great white sharks are ram ventilators which can further add to their problems. On land, the shark will thrash and expend large amounts of energy. In addition, stress hormones will build up to dangerous levels. When this happens, even when the shark is returned to the water, it might simply stop swimming, causing it to sink, be unable to get water through its gills, and effectively drown.
Are There Shark Species That Can Survive Out of the Water?
Some shark species have evolved to survive for periods out of the water. The most well-known of these is the epaulette shark (Hemiscyllium ocellatum).
Epaulette Shark
Epaulettes are found in the shallow, tropical waters off New Guinea and Australia, often living in tidal pools.
These pools can sometimes become isolated from the sea, and as a result, the dissolved oxygen levels in the water can drop 80% or more. This has caused the epaulette to develop an ability to tolerate extremely low oxygen levels.
In fact, scientists have studied epaulette sharks surviving with no ill effects after being kept with just five percent of the usual amount of oxygen for up to three hours.
Reading Suggestion: Can Bull Sharks live in Freshwater?
In addition to being able to survive in water with low levels of oxygen, the epaulette has evolved to live outside deep water and can walk from one tidal pool to another by wrigging and pushing itself along with its fins.
By keeping its gills damp and tolerating low oxygen levels, this shark can survive out of the water sufficiently long to get to the next pool unharmed.

Can a Bamboo Shark Breathe on Land?
Bamboo sharks (Hemiscylliidae) are a family of sharks found in shallow waters in the tropical Indo-Pacific. Bamboo sharks cannot breathe on land in common with all other sharks.
Like the epaulette shark, they often live in tidal pools and may tolerate lower than normal oxygen levels. Bamboo sharks also use their pectoral fins to walk along the bottom, allowing them to move in shallower water than would usually be possible.
However, bamboo sharks still need to keep their gills wet, and in contact with water, or after extended periods they will suffocate.
Conclusion
How long can a shark survive out of water is very difficult to answer. After just a few minutes, large sharks will almost certainly suffer damage from a low oxygen level. Most sharks will experience internal bleeding and organ damage due to the effects of gravity on their large bodies.
Reading Suggestion: The Incredible Life Cycle of a Shark
Smaller sharks may be expected to survive for longer, although if their gills get dry, they too will suffer lasting damage even if they are returned to the water.
No shark can breathe on land, but some small sharks have developed the ability to survive with very low oxygen levels in their blood. This allows them to survive in waters with low amounts of dissolved oxygen or on land for more extended periods. However, even these unique sharks will perish if their gills dry out
Do sharks drown if they stop swimming?
There’s a common notion that sharks need to swim continuously or they will drown. This myth has certainly become an overused trope when it comes to motivational quotes, but is there any truth to it? Can a shark actually drown if it stops swimming? Let’s investigate!
Sharks have two methods of breathing, i.e. getting oxygen-rich water to flow across their gills. The first method is “ram ventilation” – the shark swims with its mouth open and its speed pushes water through its gills, if it stops swimming, it stops breathing.
The second method is called “buccal pumping”, which is basically a process where they use their cheek muscles to suck water through their gills.
Many of these sharks make obvious use of this technique by lying completely still on the seabed, sucking water in through spiracles (modified tubes just behind their eyes) so that they can keep their mouths closed while breathing.
You might be forgiven for thinking that most sharks do not fit the cheek-sucker description, but the reality is that of the over 400 species of shark that currently inhabit our ocean, only about 20 of them are “obligate ram ventilators”. In other words, most sharks suck.
Most sharks use a combination of these two techniques, switching back and forth depending on how fast they are swimming. Even stereotypical-looking sharks, like the ragged-tooth sharks in the Save Our Seas Foundation Shark Exhibit at the Aquarium, are capable of this, using buccal pumping to supplement their ram ventilation when they are swimming at slow speeds.
So, while most sharks will be 100% fine if they stop swimming, a few iconic species such as great white sharks, whale sharks, hammerheads and mako sharks would suffocate without forward motion or a strong current flowing towards their mouths.
In answer to our titular question – NO, most sharks will not drown if they stop swimming. Which brings us to another question: Can sharks swim backwards? (You’ll need to wait and see!)
The Shark That Can Walk on Land
Yes, you read that right—there is a shark that can walk on land. The incredible epaulette shark is not only a perfectly capable swimmer, but it can also “walk” between coral heads at low tide, along the seafloor, and even on land when needed. For that reason, it is often called the “walking shark.”
How can epaulette sharks walk on land?
There are a couple of impressive evolutionary adaptations at work here. First is the ability to walk. The environments that epaulette sharks inhabit are complex, shallow, obstacle-filled coral reef systems. In order to successfully navigate the cracks and crevices of this habitat while pursuing their prey (crustaceans, worms, and small fish), epaulette sharks evolved the ability to walk along the seafloor using an undulating, crawling motion. This movement is possible through evolutionary adaptations in their pectoral and pelvic fins that have increased their range of motion and functionality as “feet.” Even though they can swim just fine, these sharks are often seen ably walking along the seafloor or across the reef.
The second adaptation that allows the epaulette shark to walk on land is its ability to survive for extended periods of time with little to no oxygen. The reef systems that these incredible “walking” sharks inhabit can be very shallow—so shallow that during low tide isolated pools of water form between exposed reef structures. Those pools can trap fish, crabs, and other animals, and the level of oxygen in the water can drop by 80% or more through their respiration. Epaulette sharks can become trapped in those low oxygen pools, and they are also known to actually walk across exposed sections of the reef to hunt for prey in places where other predators can’t go and prey have little chance of escape. To be able to survive with little or no oxygen in those situations—as they pursue isolated prey, or escape from low-oxygen tide pools—epaulette sharks have evolved the ability slow their heart rate and breathing, and to gradually limit blood flow to certain parts of the brain.
Together, the epaulette shark’s ability to a) walk on its pectoral fins, and b) survive for extended periods with little or no oxygen allow these incredible sharks to actually walk on land.
Where can you see walking sharks?
We often see walking sharks on our Raja Ampat liveaboard snorkeling trips in Indonesia, and it is common to find them walking across the seafloor or reef. They are most active at dawn and dusk, so we frequently see them during nighttime snorkeling excursions at Aljui Bay (we usually arrive as the sun is setting), and, with luck, on the morning of our bird of paradise outing. We visit the bird leks just before dawn, and return around 8am. If it happens to be low tide, we sometimes see the sharks walking across the tops of coral heads in search of prey. We also sometimes encounter them resting during the day, usually tucked under a coral head or wedged in a crack on a wall face.
Here are some photos and video taken by Wayne Sentman, our director of conservation travel programs, during Oceanic Society expeditions:
There are nine known species of walking shark (Hemiscyllium spp., commonly called epaulette, carpet, or bamboo sharks) that are found only in Australia, Indonesia, and Papua New Guinea. New walking shark species are still being discovered as scientists explore the diverse Coral Triangle region, including one in 2013 (Hemiscyllium halmahera) and in 2006 (Hemiscyillum freycineti). All epaulette sharks are known to walk across the reef and seafloor, but it is Hemiscyllium ocellatum (most commonly called the epaulette shark) that has been most widely studied for its ability to walk outside of the water.
