How Do Turtles Sleep Underwater?

The article discusses the intriguing sleeping patterns of turtles, emphasizing their ability to do turtles sleep underwater. Turtles adopt a unique physical mechanism to achieve this, involving a reduction in metabolism, heart rate, and oxygen consumption.

By employing these adjustments, turtles can stay submerged for extended periods without the need to breathe. The article assures readers a simple and accessible explanation of the can turtles sleep underwater mechanism, avoiding complex scientific terminology.

How do Turtles Sleep Underwater?

The sleeping is more like a resting state for the turtles. Each turtle has a different spot where they prefer do sea turtles sleep underwater sleeping. In that particular place, the turtle feels comfortable and safe.

The article highlights the curiosity of scientists regarding the ability of turtles to stay underwater for extended periods while sleeping. Researchers closely examined the sleeping cycle of turtles and found that they adapt to a unique body mechanism.

During sleep, do red eared slider turtles sleep underwater lower their overall metabolism, resulting in reduced heart rate and body functionality. This decrease in metabolism leads to lower oxygen consumption, allowing turtles to remain submerged for extended periods.

However, the article notes that turtles cannot sustain this state indefinitely, as they periodically surface to breathe by bobbing their heads above the water before returning to their sleeping position.

So, you can see turtles do not sleep like us humans without any break. In most cases, the captive turtles sleep 3 to 4 hours and then come to the surface for air. This goes on until their sleep is complete. For this on and off cycle, scientists refer to it as a resting state how do turtles sleep underwater.

Where Do Turtles Sleep Underwater?

I have mentioned earlier that each species has a different favorite spot for sleeping. It can slightly vary for the captive turtles, but for the wild turtles, this is universal.

If you have ever asked yourself,” where do turtles sleep?”, this section is for you. Most aquatic and semi-aquatic turtle species, like map turtles, red eared sliders, musk turtles, painted turtles, mud turtles sleep at the bottom of the lake, pond, river, or tank.

Map turtles, both in the wild and in captivity, prefer sleeping do painted turtles sleep underwater in low vegetation or marshy areas. During how long do turtles sleep underwater their sleep cycle, they employ the special physical mechanism discussed earlier.

In contrast, marine or sea turtles exhibit a preference for sleeping on the water’s surface in deep waters or in shallow areas surrounded by coral outcroppings and rocks. The common sight of do baby turtles sleep underwater near underwater reefs close to the shore is highlighted as an example of this behavior.

The article highlights the diverse sleeping patterns of different turtle species. Painted turtles, snapping turtles, and softshell turtles bury themselves in sand or mud at the bottom of bodies of water.

Baby turtles rest on the water’s surface, but for deeper or nighttime sleep, they may prefer the bottom of the tank. The article emphasizes that turtles don’t always sleep in the same location; their resting places can change based on comfort and temperature.

Additionally, not all turtle species sleep in water; examples include box turtles, which spend nights in tree holes or dig burrows, and desert turtles, which also burrow in the ground.

How Do Turtles Breathe Underwater?

I am sure many of you are wondering about the breathing mechanism of turtles. “How can the turtles breathe underwater?” “Do the turtles have lungs?” Let’s take a closer look at the breathing mechanism of turtles and you will get your how long can turtles sleep underwater answers.

You already know turtles drop their metabolism and heart rate during sleep. This helps the species consume less oxygen and remain underwater for hours. From time to time, the turtles come to the surface, breathe air, and get back to the resting state. But what makes the turtle breathe in both the media?

The answer is simple. Most turtle species are bi-modal. It means they can breathe in both air and water media. The gas exchange capacity is different for all the turtle species. For example, the softshell turtle is one of the rarest species that can 100% fulfill its oxygen requirement even in the water.

The scientists claim that softshell turtles absorb 70% oxygen via their skin. For the rest, they depend on their pharynx. The throat or pharynx contains tissues with blood vessels, which work as a great surface for oxygen absorption. This type of breathing is referred to as how do sea turtles sleep underwater pharyngeal breathing.

Similarly, you will find unique respiration techniques in painted turtles and musk turtles. The painted turtles have real muscles that are designed for gas exchange even in water. While the musk turtles use their neck for underwater breathing. These two species can spend months in the water without coming to the surface during the brumation period.

The turtles adapt to the same breathing process during the brumation or hibernation process.

Have you ever heard the phrase, “Turtles breathe out of their butt.”? Well, I am not indicating the literal meaning of course. The technical term is cloacal respiration.

In most turtles and reptiles, this type of breathing process is observed. Even some turtles have the physical ability to switch to anaerobic respiration. Here, the turtles can drop their overall metabolism and do not absorb any water.

In a sense, you can compare the underwater sleeping process to brumation or hibernation. It is because, in both processes, turtles drop their metabolism, heart rate, and oxygen consumption. Also, they tend to switch to specific breathing mechanisms in case the sleep is long.

How Long Do Turtles Sleep Underwater?

On the other hand, the sleeping period is different. Depending on the species, a turtle can sleep 4 to 7 hours a day. As I have mentioned above, the turtle’s sleep is not as smooth as ours. They have to come to the surface for breathing from time to time.

In low temperatures like 70 or 75 degrees Fahrenheit, the turtles can stay a bit longer underwater. Why? It is because their metabolism becomes slower when the temperature drops. And now you know, a slow metabolic rate means less oxygen usage.

Again, during the hibernation or brumation period, the turtles can spend months underwater. Yes, they even do not come to the surface for air every day. This happens due to the severe cold. In some regions, the turtles hibernate for 5 to 7 months.

This is a common question. Do turtles sleep every day? Or when do turtles sleep? Well, the sleeping cycle of turtles can be different. But all of them sleep at night. Other than that, you may find your pet resting most of the time throughout how long can sea turtles sleep underwater the day.

A healthy turtle will sleep every day for at least 4 to 7 hours. That is why experts suggest maintaining a day and night cycle inside the tank. It means the heating bulb of the tank should be on for 10 to 12 hours during the day. And at night time, keep it turned off. You can use red light that does not irritate the pet’s eyes.

Do you know the sleeping cycle of a pet can indicate its health status? Usually, the babies or the hatchlings are more active than the older ones. So, they sleep less and spend more time swimming, how can turtles sleep underwater playing, or resting.

On the other hand, adult or old turtles will do the exact opposite. They sleep more and do less activity. So, if you see your hatchling sleep a lot, there is definitely something wrong. This is the same for an ill turtle.

However, a stressed turtle can not sleep well. This can lead to appetite and weight loss. No matter how old your pet turtle is, keep an eye on its sleeping cycle. Adjust the tank temperature to make the perfect sleeping environment for the pet.

Can Turtles Drown?

Most turtles spend almost their life in the water. So, when you ask if a turtle can drown or not, this may sound a bit awkward. Do not worry about the drowning of your turtle. They know their way out and how to survive in the water.

Moreover, a turtle can stay underwater for several hours even if they do not get any air. They have the mechanism to adapt to the environment quickly. But it is not rare that turtles are drowning.

When does a turtle drown? Only if the turtle is trapped or weighed with a heavyweight, it may drown. Also, the cases can be observed among the baby turtles.

As the lungs of the hatchlings are not developed yet, they might not be able to stay underwater for so long. Eventually, the pet may end up losing its life. To avoid this type of accident, make sure the water level is perfect for the baby turtles.

Sleeping Place For Pet Turtles

I have discussed the preferable sleeping places for different turtles. But how will you ensure a perfect sleeping spot for your pet turtles? Of course, you can not replicate the exact wild environment. That does not mean you will not why do turtles sleep underwater even try.

I suggest providing several hiding places in the enclosure. Place those visual barriers in a shallow area. You also have to place submerged logs that can aid the turtles to come to the surface. For safety, install airstone or air spaces for the pets.


Did you have fun learning the unique sleeping pattern of the turtles? Sleep is a relaxation process even for these pets. So, create a suitable underwater resting and sleeping environment for the turtles.
