How Long Do Red Eared Sliders Brumate? [4+ Months?]

The information is current and up-to-date in accordance with the latest veterinarian research.

Red eared sliders like to brumate in the winter. Turtles that live in the wild also usually brumate during the winter months. So, how long do red eared sliders brumate?

Red eared sliders usually for 3 to 4 months during the winter season, and sometimes longer if the cold weather does not change.

Red eared sliders live in lots of different places where it can get very cold during the winter months. Even as pets, they do not lose the ability to brumate. But for them to brumate, certain conditions need to be fulfilled. If you are a pet owner, you should know about these conditions if you want your red eared sliders to brumate.

How Long Do Red Eared Sliders Brumate?

Pet turtles usually brumate when it is cold outside. As they are mostly housed indoors where the temperate can be controlled, it does not get too cold for them to start to hibernate. It is a very common occurrence for pet turtles to brumate.

As red eared sliders are very sensitive to subtle temperature changes when winter arrives, the temperature inside the house falls and the turtles take this as a sign that winter is coming.

Thus, they reach a state of brumation but because the temperature inside the house does not drop sharply, they never reach the state of hibernation as it is not required.

If you want your turtles to stop brumating, you need to ensure that the temperature of its tank and enclosure is high enough.

What is Brumation?

Brumation is a state which the turtles reach just before hibernation. When the temperature is slightly cold, turtles will brumate to conserve their energy and sustain themselves through the low temperatures. If the temperature becomes too cold, then the turtles will start to hibernate, coming out of their state of brumation.

In the wild, it is very hard to find reliable sources of food, especially during the colder months. Thus, red eared sliders have developed this state where they don’t need to look for food or water to survive.

During the winter, very little vegetation is able to grow and this puts the animals of being at risk of starvation. Turtles such as the red eared sliders become less active during the cold weather, and that is why they brumate in order to survive during the cold weather.

They take a break until the winter is over and things return to normal.

What Happens When A Red Eared Slider Brumates?

During this state, red eared sliders will do very little physical movements and will try to conserve their energy. If you find your pet turtles not doing anything, then this means that they are brumating.

Brumation and hibernation are two very similar things. They only have one major difference and that is hibernation is a state in which red eared sliders are sleeping and brumation is a state in which red eared sliders are awake.

When the turtles start to brumate, their heart rate slows down along with the rate of breathing. They eat very little food, and at other times they eat nothing. During this state, they do very little physical movements.

Brumating turtles will not look for any food or water, they won’t bask, and most of the time they will just move around and do nothing else. Sometimes, you will even find turtles that are brumating to be just stuck in the same place for hours and hours.

Brumation is the state which the turtles reach when their surrounding temperature is low, but not too cold that they would need to hibernate. Nothing much can be said about this state other than turtles not doing anything. It is a state just before hibernation, and it also helps them to cope up with cold weather.

How Brumation Helps Red Eared Sliders Survive Cold Winter?

When it starts to get cold, turtles will become less active and slow down their rate of metabolism. This results in a drop in heart rate and they will slow down their movements as well as other functions inside their bodies.

Usually, the heart rate of a healthy turtle is 45 beats per minute. A brumating turtle will have a heart rate of around 10 beats per minute, which means their bodily functions are slowed down drastically during this state.

This slowdown in heart rate helps red eared sliders to survive with less oxygen. Even in situations where they have no access to oxygen, they can survive for 5 to 6 months. Turtles can even live without any food or water for up to 8 months while they brumate. Their cold-blooded nature also helps them to conserve energy as they don’t need to generate their body heat.

Turtles vs Other Animals While Brumating

Turtles are reptiles, which are unlike other animals that brumate because they are mostly mammals. Belonging to a reptilian species mean that red eared sliders are cold-blooded animals.

Cold-blooded animals are unable to generate their body heat and they depend on the temperature of their surrounding environment to get heat. Thus, red eared sliders are able to detect subtle temperature changes in the environment.

Other animals that brumate are usually warm-blooded animals which means that they spend energy to keep their bodies warm. As red eared sliders are cold-blooded reptiles, they have to be very careful regarding the location in which they choose to brumate. If the location is too cold, it might affect their body temperatures. Thus, being a cold-blooded reptile has its perks and disadvantages.

Side Effects of Brumation on Red Eared Sliders

When the turtles brumate, they slow down their metabolism to such a rate that it allows their bodies to build up more lactic acid. Brumating turtles fail to get rid of this excess lactic acid, which results in sore muscles. Thus, this side effect causes them great discomfort, especially when they wake up after a long sleep only to suffer from painful muscle cramps.

Brumating turtles are also not able to grow. This is because they require magnesium and calcium for their growth, elements that they will use to get rid of the lactic acid while they are in a state of brumation. This is another bad side effect, and growth is pivotal for their survival as the bigger the turtles get, the higher their chances of surviving from predators in the wilderness.

Where Do Red Eared Sliders Brumate?

Turtles will usually brumate near fresh bodies of water, or in places that are well hidden from the surrounding environment. They will look for a spot that will allow them to keep sufficiently warm during their brumation.

Red eared sliders usually prefer to brumate underwater. In circumstances where they don’t have this option, they will try to locate other places where they are protected from the cold weather. Once they find a place, they will brumate until the winter months pass by and then they will come out of their spots.

Red eared sliders that are bred in captivity will also brumate if their surrounding temperature gets too cold. Pet turtles need a suitable location to brumate, and if you fail to provide sufficient habitat for them, they won’t go in brumation. Most tanks that are used to house pet turtles are not a sufficient location for brumation.

Is Brumating Harmful For Turtles?

If you are a pet turtle owner, you should not be worried if you see your turtles not moving much or doing anything. It just means that they are starting to brumate and you don’t have to feed them anything.

Young turtles that are just 1 or 2 years old should not be allowed to brumate. You can prevent your young turtles from brumating by raising the temperature of your room as well as the temperature of the water tank where your turtles are located.

As red eared sliders are sensitive to temperature changes, they will immediately notice the warm temperature and snap out of their state of brumation. Young turtles stop their usual growth rate when they are brumating as they eat very little food or water.

Keep in mind that baby sliders are not fit to brumate. If your sliders are less than 3 years old, then you should not let them brumate as it may affect their growth rate. If your pet sliders are of mature age, then you can let them brumate and it won’t be a cause for concern.

Key Differences Between Hibernating Turtles and Brumating Turtles

As you have already read, there are subtle differences between a brumating turtle and a hibernating turtle. Brumating turtles are awake while hibernating turtles are in a state of deep sleep.

Red eared sliders that are in brumation move very little, while hibernating turtles will not move at all. Brumating turtles will sometimes eat a little bit of food, but hibernating turtles will not eat anything at all for many months.

The table below lists some of the distinctions between brumating turtles and hibernating turtles.

Frequently Asked Questions

Red-eared sliders do not technically hibernate, but they do brumate, which is a passive state that can last around three months. During brumation, they become less active and may not eat or drink much, but they can still move around if necessary.

Pet red-eared sliders can also brumate, but they are less likely to do so since they are usually kept indoors where the temperature is warm.

In their natural habitat, Red Eared Sliders have been known to live from 30 up to 60 years. They typically live between 20-30 years in captivity, although some individuals can live for more than 70 years.

Red-eared sliders hibernate in the winter when the temperature drops low enough, typically below 50 degrees fahrenheit. However, if the temperature doesn’t drop enough, they will brumate instead.

Turtles generally do not eat during brumation. During this time, their metabolism slows down, and they become less active. They may also not drink or defecate for several weeks.

However, if a turtle wakes up from brumation due to a temporary increase in temperature, they may eat and drink before returning to brumation.

Red-eared sliders typically brumate during the winter months, starting around October or November and lasting for about three to four months, until the temperature increases.

However, the exact timing of brumation can vary depending on the location and the individual turtle’s health and age.

It is not recommended to intentionally induce brumation in pet red-eared sliders unless you are an experienced turtle keeper and have consulted with a veterinarian.

However, if you live in an area where the temperature drops naturally and you notice your turtle becoming less active and eating less, you can create a brumation-friendly environment by gradually lowering the water temperature to around 50-60°F (10-15.5°C). Also, reduce the lighting hours to simulate the natural winter conditions.

Final Words

In conclusion, there is nothing wrong if adult sliders are brumating. Brumating depends on the temperature of the surrounding, and if your place is going through a patch of bad weather, then it may prolong the state of brumation of your pet sliders.

As soon as the winter passes by, turtles will detect the temperature change and snap out of their state of brumation.
