Have you ever wondered if turtles dream? Despite the fact that they are one of the oldest and most widespread groups of reptiles on the planet, little was known about their sleep patterns and whether they dream. But recently this has changed. In this article, we’ll explore the question, “Do turtles dream?” and what the current research says about it.
Studies have shown that turtles go through periods of rapid eye movement (REM) sleep, which is when dreaming occurs. During the REM sleep, turtles have also been observed to make small movements with their body, which further indicates that they might be dreaming.
But what do turtles dream about? Again, we cannot know for sure, but scientists have observed some interesting behaviors during REM sleep in turtles, which gave them a few hints.
What Turtles Dream About
Some turtles have been observed making movements that suggest they are swimming or digging, activities they would do while awake.
Furthermore, some researchers have speculated that turtles may dream about familiar places or situations. In one study, researchers observed that turtles who were kept in tanks with specific landmarks had increased brain activity in the areas of the brain associated with spatial navigation during REM sleep. This suggests that they may be dreaming about navigating their tank and its surroundings.
Of course, we may never know for sure what turtles dream about. But the evidence suggests that they do indeed dream, and that their dreams may involve activities and places that are familiar to them.
It is important to note that while turtles may dream, they do not have the same level of consciousness as humans, and their dreams likely serve a different purpose. However, studying the sleep and dreaming patterns of turtles and other animals can help us better understand the evolution and function of sleep and dreams in general.
While there is some evidence to suggest that turtles dream, there are still many unanswered questions about their sleep and dreaming patterns. For example, we do not know how frequently turtles dream, or whether their dreams are influenced by their environment or experiences.
Why the Way Turtles Sleep Is Different
One interesting aspect of turtle sleep is that it differs from that of other animals in some ways. For example, turtles have been observed to sleep with only one hemisphere of their brain at a time, a phenomenon known as unihemispheric sleep. This allows them to rest and remain alert to potential dangers at the same time. It has been suggested that this adaptation may have evolved as a way for turtles to sleep safely while floating on the surface of the water.
Furthermore, researchers have also studied the sleep patterns of sea turtles, which face unique challenges due to their marine environment. Sea turtles have been observed sleeping while floating on the surface of the water, or while resting on the sea floor. They are also able to sleep while swimming, with their body position and movements controlled by their subconscious brain.
Studying the sleep and dreaming patterns of turtles and other animals can also have practical applications. For example, understanding the sleep patterns of sea turtles can help us develop conservation strategies to protect them from disturbances caused by human activities such as boat traffic and beach development.
Interestingly, some scientists have also studied the effects of sleep deprivation on turtles. In one study, researchers kept turtles awake for extended periods of time and observed changes in their behavior and brain activity. They found that sleep-deprived turtles had increased levels of stress hormones and showed signs of impaired cognitive function. This suggests that sleep is important for the health and well-being of turtles, as it is for humans and other animals.
While sleep deprivation experiments are not considered to be ethical today, that wasn’t always the case. At the moment, there are no similar experiments being conducted.
Another interesting aspect of turtle sleep is that it can vary depending on their life stage. For example, hatchling turtles have been observed to sleep for longer periods of time compared to adult turtles. This is likely because hatchlings need to conserve energy and grow rapidly, whereas adult turtles have lower energy demands and are more focused on activities such as foraging and mating.
Furthermore, some species of turtles have been observed to go through periods of dormancy or hibernation during the winter months. During this time, they may not eat, drink, or move, and their metabolic rate decreases significantly. This allows them to conserve energy during times when food and water may be scarce.
Studying the sleep and dormancy patterns of turtles and other animals can also have medical applications. For example, understanding the mechanisms that allow animals to enter and exit states of dormancy could have implications for human medicine, such as developing treatments for conditions that involve prolonged immobility or decreased metabolic rate.
Final Thoughts
While we cannot directly ask turtles about their dreams, there is evidence to suggest that they do dream. Further research in this area may provide more insights into the sleep and dreaming patterns of turtles and other animals, and the role they play in their lives.

Related Questions
Should I live the lights on for my pet turtle during the night? No, turtles don’t need a light during the night. But if you want to look at your turtle during the night, you can buy a special light just for that. They are very dim, usually red or blue lights, that were created just for that purpose.
How long should you leave a light on for a turtle? The best practice is to let the lights on the same amount of time that the sun is in the sky. The winter is the only exception, because the sun is up for a very short period of time. During the winter, you leave the lights on for 10 to 14 hours.
Can turtles see humans? Yes, turtles are able to see humans very well, and they are also able to distinguish between us, based just on physical appearance.
How long can a turtle stay underwater ? It depends on the turtle, most sea turtles will be able to go for at least 5 hours without breathing, most aquatic turtles should be able to stay underwater for at least 20–30 minutes, land turtles on the other hand are not very good at staying underwater so 1 minute is the average you can expect them to be able to stay underwater. Here is a list of average times a turtle can spend underwater:
- Box turtle – 1 – 2 minutes
- Desert tortoise – 1 – 2 minutes
- Snapping turtle – 20 – 30 minutes
- Red-eared slider – 20 – 30 minutes
- Map turtle – 20 – 30 minutes
- Green sea turtle – 7 – 10 hours
- Leatherback sea turtle – 7 – 10 hours
- Kemp’s Ridley – 7 – 10 hours
- Olive Ridley – 7 – 10 hours
