Can Turtles See In The Dark? Everything you Need To Know

Turtles are an amazing creature. Some species of turtle are often spotted at night. This is most often true for sea turtles, who lay their eggs at night. If you are wondering whether turtles can see in the dark or not, you aren’t alone. 

Turtles aren’t considered to have night vision, but that doesn’t stop them from seeing when it is dark out. Turtles do have the ability to see in the dark, but their vision is not very clear. Once their eyes have time to adjust to the darkness, they can see what is around them a little bit better.

You might also be wondering if turtles are nocturnal. They are not, because they don’t sleep during the day to be active at night. Turtles will usually find a safe spot to sleep at night to protect themselves from potential predators. 

Can Turtles See in the Dark?

When it comes to seeing in the dark, turtles will have similar vision to what we as humans have. However, unlike humans, turtles will see things around them with a reddish tint in the dark. This is because the color palette in their eyes has extra shades of red.

For example, think about looking at the night sky on a starry night. As humans, we will usually see the sky with a blue or even a dark tint. Turtles will see the stars with a red tint instead of blue. Think of it almost like looking through the red side of a pair of 3-D glasses.

When we humans find ourselves in the dark, we won’t see what’s around us right away. After a short period of time, our eyes adjust, and we can see a little bit of what is around us. Turtle’s vision works in the same way. When they are in the dark, they can’t immediately see what is around them.

They won’t have very clear vision in the dark, but they will be able to see enough to get around. This answers the question of whether sea turtles have night vision. If turtles had night vision, they would be able to see clearly in the dark. 

If you have a turtle for a pet and you are wondering whether they need a light to get around their tank at night, it’s not likely they will need one. However, if you would like to have a night light for them, it is preferrable to have the light red, blue, or purple. This will make it easy for your turtle to see without keeping it up all night.

In addition to helping the turtle see better in the dark, night lights also help keep your turtle’s body temperature at an appropriate level to prevent any possible infections they might come in contact with. Don’t keep them too close to the turtle, or it can burn the turtle.

How Far Can Turtles See in the Dark?

Turtles have different lengths of vision in and out of water. They can see further in the water because they are far-sighted. However, they can’t see very far out of water because they are near-sighted. Turtles do not have peripheral vision, so they can’t see beside themselves without turning their head. This is also true in the dark.

The ability to see a certain length in the dark depends on if there is any surrounding light. In most instances, the moon will be able to reflect off of objects that turtles can’t normally see when it’s dark. Due to their limited vision in the dark, most turtles will find somewhere safe to sleep at night instead of wondering around.

If you are concerned about your pet turtle not being able to find its way through its tank at night, you shouldn’t worry too much. Your turtle will more than likely be able to see far enough to make their way around in the dark.

Your pet turtle will also be able to see enough to find its way around your backyard if they roam free. They will be able to see a few feet in front of them, which is enough to determine if there is anything in their way that they need to avoid.

Do Turtles Have Good Eyesight?

Since most turtles are aquatic, or at least semi-aquatic, they spend the majority of their time underwater. This is where their eyesight will be the best, but they have the ability to see clearly on land and in water. This is because they have flat corneas with spherical lenses.

Turtles have really good eyesight. Their sight is so well developed that they can quickly and easy change their eyes for seeing above and under water. This makes it easy for them to find food for themselves and their families. 

Their eyesight is also good enough that they can see color. The ability to see colors makes it possible for them to evade predators and distinguish between what food they are going to eat. They can also make out shapes and patterns.

The eyesight of a turtle is so good that they can see and memorize what their owners look like. Some owners even state that their turtles swim up to the front of the tank when they enter the room. Turtles can also tell the difference between characteristics in different people.

Vegetables play a large part in how well a turtle can see. Turtles need an efficient amount of Vitamin A in their diet because their bodies don’t store this nutrient. If a turtle doesn’t eat enough Vitamin A, their eyelids can start to swell, and they can start to have problems with their eyesight.

How Do Turtles See Color?

For a while, it was thought that turtles can’t see colors at all. It was believed that turtles say the world in black and white, but it has since been proven to not be true. Turtles have shown that they can differentiate between different colors easily.

Research has shown that not only can turtles see colors, but they can also have favorite colors and show color preference. For example, they are going to be more interested in eating foods that are orange, red, and yellow.

Turtle owners have reported that they see their turtles being obsessed with the color yellow. If they see the color, they won’t be able to take their eyes off of it. Some turtles love to eat bananas, and this could have something to do with bananas being the color yellow.

Red is also often reported as a color that turtles can’t seem to get enough of. They can even see shades of red that we can’t comprehend. This is due to a gene that they share with dinosaurs, called CYP2J19. They are attracted to red because it is in their genes.

Orange is a color that some turtles don’t like much. Turtles will sometimes hide in their shells when they are presented with something that is orange. They will also go out of their way to avoid fish that are orange. 

Different turtles will have different responses to colors. It would be an interesting experiment to try out with your turtle to see which colors they respond best to. This can steer you in the right direction for their food as well, as turtles will eat foods in the color they are attracted to.

The color of your turtle toys even matter. If your turtle doesn’t like a certain color, they will cower from it and start to act funny. Try taking the toy out of the tank to see if your turtle starts to act normal again. If they do, it could be the color of the toy.

Turtles even have the ability to see an extra color that us humans can’t see. The human eye can see three wavelengths of light that are red, green, and blue to make up the millions of colors we see. Turtles have an extra ability to see another shade of red wavelengths. This means they can see more colors than we can.

How Do Turtles See the World?

When considering how turtles see the world, there is more to take into account than just what they see. They use all of their senses to determine what their environment is like. Just like humans, the way turtles see the world is unique to each turtle.

The turtle eye is sometimes referred to as the camera eye. This is because the eye of the turtle has some of the same components as a camera lens. Turtle eyes have an iris that can easily adjust to different levels of light and focus in on an image.

Turtles have a lateral eye position that benefits them in several ways. There are six muscles that work together to move the turtle’s eye, and the muscles that control the lateral eye are different than those that move forward facing eyes. 

In the eye of a turtle, there are cells that detect movement and cells that detect colored light. Turtles will usually have an even amount of movement detecting cells and color detecting cells in their eyes. This helps with their perception and how they see things around them.


If you are wondering whether or not turtles can see in the dark, it is not an uncommon question. Turtles are such interesting creatures, and we only know so little about them. It is sometimes common to see turtles wandering around at night, begging the question of whether they are nocturnal.

Surprisingly, turtles can see in the dark in the same way that we as humans can. They don’t have clear vision and it takes their eyes a few minutes to adjust to darker settings. They also can’t see very far in the dark, so they will usually find somewhere safe to sleep at night.

Turtles have great eyesight because their eyes can adjust from underwater vision to on the surface vision in just a few seconds. Turtles can see just as clearly in water as they can on land due to how their eyes are constructed. Their eyesight also depends on if they get enough Vitamin A in their diet.

If you are wondering if you need a night light for your domestic turtle, it is not necessary. If you do want to keep a light on for your turtle, make sure the light isn’t bright enough to keep them awake all night. They will typically prefer colors like red, purple, or blue for sleeping.
