No, sea turtles do not have lungs or gills. Instead, they have organs called “buccal pumps” which allow them to take in oxygen and expel carbon dioxide. This allows them to breathe underwater. They are able to stay underwater for extended periods of time by inhaling and exhaling the water around them.
Oxygen is exchanged through the walls of their intestines and skin as well. This type of breathing is known as “bentonic” rather than “pulmonary” breathing, which relies on lungs and gills.

Do sea turtles breathe air or water?
Sea turtles, like all turtles, are air-breathing reptiles. This means they must break the surface of the water to breathe air. Each species of sea turtle has a different pattern of how often they need to surface to breathe, depending on the size and species.
For example, leatherback turtles can stay underwater for up to 85 minutes, while green turtles typically breathe every 4-5 minutes. This means leatherback turtles can travel deeper and farther away from shore than most other sea turtle species.
When sea turtles are resting or sleeping, they often remain underwater for many hours, using oxygen stored within their blood and body cells.
How long can a sea turtle stay underwater?
Sea turtles can stay underwater for quite some time, depending on the species and the activity they are engaged in. Sea turtles have an incredible ability to store oxygen when they dive. Depending on the species, they can stay underwater for up to 4 hours, with a record of 7 hours in one dive.
That being said, the more active the sea turtle is during the dive, the quicker it will consume its oxygen stores and will need to surface for air. This can be especially true if the turtle is foraging for food, as it will be more active in its dives.
Additionally, young sea turtles typically can only stay underwater for up to 45 minutes, though this increases as they get older.
What animal can hold its breath the longest?
The record for longest breath-holding time in a mammal belongs to the African elephant. According to Allen’s Rule, a species’ surface area-to-volume ratio increases as size decreases, so a large animal like an elephant can retain heat better than a small one.
This adaptation allows the elephant to submerge itself in water and not need to take a breath for several minutes. An African elephant can hold its breath under water for up to 3 minutes at a time.
In terms of breath-holding time, marine mammals reign supreme. The deepest breath-hold dive on record was held by Tuffy, an elephant seal, who descended 2,388 feet (728 meters) and stayed underwater for 2 hours and 17 minutes! While this is an extreme case, most seals and whales can hold their breath for 15 minutes or longer.
How long is the lifespan of a sea turtle?
The lifespan of a sea turtle can vary significantly depending on the species. In the wild, they can live anywhere between 30 to 80 years, although some may live longer. Green sea turtles can live up to 80 years, leatherback sea turtles can live up to 50 years and loggerhead sea turtles can live up to 45 years.
Sea turtles can also live longer in captivity and can reach an age of 100 years or more.
Can turtles be fully submerged?
Yes, turtles can be fully submerged. In fact, they are strong swimmers and spend a significant amount of time in the water. Turtles are frequently found in shallow streams and ponds, but they are also well adapted for deep water swimming and can spend hours under the surface.
There are certain species of turtles that live in the ocean, and they can be fully submerged for the majority of their lives. Some turtles even dive down to the ocean depths for food or for brief periods of rest.
Whatever the species, all turtles have a special adaptation that allows them to remain under the water for extended periods of time. They have a strong cloaca, which is an outer opening that takes oxygen from the water and circulates it throughout the turtle’s system – giving them the ability to stay submerged for a longer period of time than some other animals.
Do sea turtles feel pain?
Yes, sea turtles are capable of feeling pain just like any other animal. Scientists have demonstrated that sea turtles respond to physical pain in a similar way to mammals, including other reptiles, by withdrawing from the source of pain and demonstrating changes in behavior.
Sea turtles possess nerve fibers and pain receptors in their bodies just like other animals, although it is not known to what extent they experience pain in a similar manner to humans. For example, researchers have observed sea turtles flinching away from a perceived threat and some appear to exhibit avoidance behavior, suggesting they may be able to recognize and recall a negative experience.
Additionally, when exposed to electrical shocks, sea turtles have been observed to exhibit behaviors such as increased heart rate and muscle contractions, further evidence that they may be able to perceive pain.
Although more research is needed to better understand if and how sea turtles feel pain, it is clear that they are able to sense and respond to it in some capacity.
How do turtles know to go to the ocean?
Turtles, much like other migratory species, are guided by instinct. They may also use environmental cues such as the sun, moon, stars, ocean currents and magnetism to help them orient themselves and find their way back to the ocean.
A turtle’s navigation system is likely made up of a combination of instinct and instinctive behavior due to generations of conditioning migrating back to the same location year after year. Turtles possess the ability to store memories and use them to determine which direction they need to head in order to reach the ocean.
It is believed that the magnetic fields of the earth also play a role in their ability to locate their way back to the ocean, using the earth’s magnetic lines to help them navigate their way. With the combination of all these factors, turtles are able to migrate hundreds of miles and arrive at the exact location of their birthplace year after year.
How do turtles sleep without drowning?
Turtles are able to sleep underwater without drowning due to the way their body has evolved to sustain them underwater for long periods of time. Their anatomy allows them to go into a state of torpor (which is a type of hibernation) in order to conserve energy and endure prolonged periods of sleep.
They are able to reduce their oxygen consumption by reducing their heart rate and slowing their metabolism. This state of torpor also reduces the amount of oxygen they need to consume, allowing them to sleep without drowning.
Another way turtles avoid drowning during sleep is that they stay in shallow water close to the surface. This allows them to sleep without needing to constantly use their limited energy reserves to come up for air.
It also makes it easier for them to resurface quickly if needed. Additionally, turtles that live in marine environments will take advantage of the water current to hold them in place.
Turtles also retract their heads, legs, and body into their shell and remain submerged for up to 48 hours at a time. This position helps them conserve energy, as well as reducing their overall body size, allowing them to remain submerged for extended periods of time without suffering from oxygen deprivation.
In short, turtles are incredibly adept at sleeping underwater and avoiding drowning by using a variety of adaptive strategies to reduce their oxygen consumption. This allows them to conserve energy and stay submerged for extended periods of time without respiratory distress or suffering from oxygen deprivation.
Can you throw a turtle in water?
Yes, you can throw a turtle in water. Turtles are aquatic animals, meaning they live their lives in water, so throwing them in water should not cause any harm, provided they are able to swim and escape to the surface.
Turtles require access to the surface of the water in order to breathe, so it is important to ensure that the water they are thrown into is deep enough for them to reach the surface or that there is some type of platform or structure for them to climb out on.
Additionally, it is important to make sure that the water is clean and free of any pollutants or toxins that could harm the turtle. If you are unsure about the safety of the water, it is best to let the turtle return to the water on its own instead of throwing it in.
What do turtles do all day?
Turtles, like other animals, must devote much of their time to the basic daily requirements of sleep, finding food, and keeping themselves clean. During the day, turtles will eat and lounge in the sun to help keep their temperature constant.
They may come out of the water and bask on logs, rocks, or in the sand, and will wander around in search of food. Depending on the species, turtles may search for worms, mollusks, aquatic vegetation, carrion, insects, and other animals.
They may bask in the sun for hours in order to absorb the warmth, which helps them digest their food. Turtles can also be seen playing and interacting with other members of their species. When nighttime approaches, they typically retreat to their burrows or other areas of shelter to rest, and will remain in those places until morning.
Do water turtles need to breathe?
Yes, water turtles need to breathe. Like any other animal with lungs, water turtles need to take in oxygen in order to stay alive. Water turtles have short and pointed noses so that they can breathe while submerged in the water.
They can stay underwater for extended periods of time, but they still need to surface regularly to breathe. In order to prevent drowning, they also know how to float to the surface and skip a breath of air at the top of the water.
When water turtles are on land, however, they still need to take in oxygen. Therefore, they’ll still take in air the same way that land turtles do.
