Many reptile owners have looked over at their bearded dragon and wondered if they’re actually sleeping or just resting with their eyes open. Bearded dragons tend to sleep in some quirky positions and often don’t close their eyes fully when they’re sleeping, so it can be hard to tell if your dragon is truly asleep or still wide awake.

If you’re short on time, here’s a quick answer to your question: Yes, bearded dragons typically do sleep with their eyes at least partially open.

What Does Bearded Dragon Sleep Look Like?

Eyes Open or Partially Open

One of the most unusual aspects of bearded dragon sleep is that they often sleep with their eyes open or partially open. This is because bearded dragons, like many reptiles, do not have eyelids that fully close.

Instead, they have a translucent third eyelid called a spectacles or nictitating membrane that can slide over their eye from the inside corner outwards. When sleeping, their nictitating membrane often only covers part of the eye, leaving it looking partially open.

Sleeping with eyes open is likely an evolutionary adaptation to allow bearded dragons to still monitor their surroundings for threats even while sleeping. However, even though their eyes are open, bearded dragons are still very much asleep and their brain activity slows down dramatically during sleep cycles.

Some owners may find it disturbing to see their bearded dragon sleeping with eyes open and may think they are awake or stressed, but an open eye does not necessarily mean the bearded dragon is not peacefully sleeping.

Strange Sleeping Positions

In addition to open eyes, bearded dragons often sleep in positions that seem bizarre or uncomfortable to us as humans. For example, they may:

  • Sleep vertically against walls or decorations in their tank
  • Sleep with their head tilted back over their bodies
  • Sleep with legs spread out to the side
  • Sleep with front legs extended forward while standing

These strange positions are perfectly normal and natural for bearded dragons. They have specialized toe pads that allow them to grip surfaces and sleep vertically or upside down without falling. Their skeletal structure also allows their neck to bend back over their bodies without causing harm.

Sleeping upright may allow them to absorb heat from basking lamps more efficiently as well.

The ability to sleep in unconventional positions gives bearded dragons flexibility in choosing their sleeping spot. It may also relate to their instincts in the wild, where they would sleep in locations with good sun exposure or quick access to hiding spots from predators.

As long as the bearded dragon appears relaxed while sleeping, the odd positions are nothing to worry about.

Why Do Bearded Dragons Sleep with Their Eyes Open?

Staying On Guard

Bearded dragons sleep with their eyes open for several evolutionary reasons. One is to stay alert to potential predators while resting. In the wild, bearded dragons need to be ready to flee at a moment’s notice. Keeping their eyes open while sleeping allows them to continuously scan for threats.

This behavior stems from their days as prey animals, when they had many natural enemies like birds, snakes, and larger lizards. Staying vigilant, even while sleeping, improves their chances of spotting an approaching predator and escaping.

Another reason is that bearded dragons have a transparency eyelid called a spectacle that protects their eyes when sleeping. This clear eyelid allows them to see while their main eyelids stay closed. So although their eyes appear open, the spectacle acts as a barrier, keeping their eyes lubricated and safe.

The transparency also aids their camouflage, as predators may not realize the bearded dragon is sleeping if its eyes look alert and open.

Natural Camouflage Advantage

The ability to sleep with eyes open gives bearded dragons a camouflage advantage. In the wild, they blend into rocky, desert habitats. Keeping eyes open maintains their natural camouflage even during rest by not closing an obvious facial feature.

This makes it harder for predators to distinguish them from their surroundings.

Sleeping with eyes open also allows bearded dragons to blend in with rock textures and patterns. Their eyes take on the colors and shadows of nearby rocks. This adaptive coloring breaks up their body outline, disguising their shape and location.

Overall, open eyes during sleep allow bearded dragons to remain camouflaged within their environments for better protection.

When Are a Bearded Dragon’s Eyes Fully Closed?

During Deeper Sleep Phases

Bearded dragons will often sleep with their eyes partially open, however their eyes will fully close during deeper sleep phases. This is similar to humans – when we first fall asleep our eyes may still flutter open briefly, but once we enter REM sleep our eyes will fully close and stay that way until we wake up.

For bearded dragons, their eyes will seal shut when they are in a deep, comfortable sleep.

According to reptile care websites like ReptiFiles.com and TheBeardedDragon.org, healthy bearded dragons need 10-12 hours of sleep per day. They are diurnal lizards, meaning they are active mostly during the day.

So at night when it’s dark and they feel secure, they will settle in to sleep deeply enough for their eyes to fully close.

Signs that a bearded dragon is in a deep sleep phase with eyes fully closed include:

  • Eyes sealed shut, not partially open
  • Body and muscles completely relaxed, often laying flat
  • No reaction to noises or movements nearby
  • Steady, even breathing

A bearded dragon with eyes wide open, twitching, or waking up easily is likely in a lighter sleep phase. But relaxed closed eyes indicate quality, uninterrupted sleep! Sleep is very important for their health and wellbeing.

When Very Young

Baby bearded dragons will also sleep with eyes fully closed more often than adults. According to reptile care experts, juvenile bearded dragons under 6 months old need even more sleep than full grown adults – 14-16 hours per day!

Young bearded dragons are growing rapidly, so all that sleep helps their developing bodies. When a baby bearded is in a deep, restorative sleep, you can expect its little eyes to be completely closed. This looks very cute!

Signs a baby beardie is in deep sleep include:

  • Eyes firmly shut
  • Curled up with tail tucked in
  • Not moving or twitching
  • Slow steady breathing

Baby lizards may also sleep piled together in a cute little heap. As they mature, they will sleep less heavily and keep their eyes open more when resting. But those blissful baby beardie naptimes are prime time for fully closed eyes while they recharge their rapidly growing bodies.

Tips for Determining If Your Bearded Dragon Is Asleep

Notice Their Breathing Slowing Down

One of the best ways to tell if your bearded dragon is sleeping is to watch their breathing. When awake and active, bearded dragons breathe fairly quickly. But as they start to fall asleep, you’ll notice their breathing slow down and become more relaxed.

A sleeping dragon’s sides will gently rise and fall with each breath. If you observe this slower breathing pattern, chances are your dragon is getting some shut-eye.

See If They’re Responsive

Another trick is to gently touch or pet your bearded dragon to check their responsiveness. When awake, most dragons will acknowledge being handled by moving around or opening their eyes. But a sleeping dragon likely won’t respond much, if at all, to gentle handling or stimulation.

The lack of response is a giveaway that your dragon is snoozing. Just be careful not to startle them awake!

Watch for Lack of Movement

Finally, look for a distinct lack of movement or animation from your bearded dragon. Awake dragons are often active – climbing around their habitat, basking, or looking for food. But when a bearded dragon sleeps, they become completely still other than their slow breathing motion.

If your dragon is motionless for an extended period, there’s a very good chance they are sound asleep.

By observing these signs of sleep, you’ll get better at determining when your bearded dragon is down for a nap. Getting familiar with their sleep patterns and behavior will also help ensure you don’t accidentally disturb them during rest periods.

Bearded dragons need plenty of sleep to stay happy and healthy, so it’s important for owners to respect their beauty rest!

Do All Reptiles Sleep with Their Eyes Open?

Many Reptiles Share This Trait

It is a common misconception that all reptiles sleep with their eyes open. While many species do exhibit this trait, there are exceptions within the reptile world. Lizards, turtles, snakes, crocodiles, and their relatives fall under the reptile classification.

Most types of reptiles do not have eyelids or a way to close their eyes. So when they sleep, their eyes remain open and alert to predators and threats in their environment.

Having the ability to sleep with eyes open provides reptiles an evolutionary advantage. As ectothermic creatures, reptiles rely on external heat sources like the sun to regulate their body temperature.

By sleeping with eyes open, reptiles can quickly escape dangers and reposition themselves towards warmth while remaining in restful states. This explains why pet reptiles like bearded dragons seem to sleep with eyes wide open, monitoring their surroundings.

Whileinstant awareness helps most reptiles survive in the wild, there are some exceptions within this diverse group of animals. Several reptile species have developed ways to close their eyes for comfort and protection while sleeping.

Exceptions Within the Reptile World

Certain reptiles have eyelids, protective scales, or transparency eyelids that allow them to cover their eyes when sleeping. Examples include:

  • Turtles and tortoises, which can retract their heads and close their eyes using eyelids when resting.
  • Snakes like pythons and boas, which have spectacle scales that protect and cover their eyes while sleeping.
  • Geckos and tuataras, whose eyes have adapted thin membranes that act as eyelids over their eyeballs.
  • Crocodiles, with valves that close to protect eyes when underwater.

So while many lizards, small snakes, and other reptiles sleep with eyes fully open, some have developed modified eyelids or scales to block out light and dangers for deeper, more undisturbed rest.

Reptile Types Ability to Close Eyes During Sleep
Lizards and small snakes No, eyes remain open
Turtles and tortoises Yes, retractable heads and eyelids
Large snakes Partially, with spectacle scales
Tuataras and geckos Partially, with nictitating membranes
Crocodiles Yes, with protective valves

As seen in nature, eye anatomy correlates with sleep habits across the over 10,000 classified reptile species. Next time you see your bearded dragon or pet snake sleeping, take a closer look at its eyes. Chances are they’ll remain creepily wide open!

Conclusion

So in summary – yes, it is perfectly normal for a bearded dragon to sleep with its eyes open or partially open. This helps them stay alert to potential predators and dangers in their environment. Pay attention to their breathing, movement, and responsiveness to determine if they’re fully asleep.

And know that many fellow reptile owners grapple with this same question of whether their pet is actually resting or still awake and alert!
