A bearded dragon's head primarily features two natural openings: its mouth and its ears. Other openings or unusual indentations on its head are generally not natural and may indicate a health issue requiring veterinary attention.
The Natural Openings on a Bearded Dragon's Head
Bearded dragons, like many reptiles, have specialized anatomical features adapted for their environment and survival. On their head, two main types of openings serve essential functions:
The Mouth
The most prominent opening on a bearded dragon's head is its mouth. This large opening is located in the middle, at the very front of the head. It is the primary means by which bearded dragons consume their food and water.
- Function: The mouth is crucial for ingesting food, ranging from insects to vegetables, and for drinking water. It houses their tongue, which is essential for capturing prey, and their small, sharp teeth used for gripping and tearing food.
- Appearance: When closed, the mouth forms a thin line across the lower part of the snout. When open, it can reveal a surprisingly wide gape, allowing them to swallow relatively large prey items.
- Care Tip: Regular inspection of your bearded dragon's mouth can help detect signs of illness, such as mouth rot, discoloration, or injuries.

The Ears
Bearded dragons possess two distinct ear openings, one on each side of their head. These are positioned slightly towards the back of the head, behind their eyes.
- Function: While they do not have external ear flaps like mammals, these openings are vital for their hearing. They lead to an internal tympanic membrane that vibrates in response to sound waves, allowing the dragon to detect environmental noises, including predators and prey.
- Appearance: Bearded dragon ears typically appear as circular or oval-shaped indentations on the sides of their head. They are often covered by a thin, translucent membrane.
- Sensitivity: Reptiles have a different range of hearing compared to humans, often sensitive to lower frequencies.
- Care Tip: Keep the ear openings clean and free from debris, although they generally require minimal intervention. Avoid introducing anything into the ear canal.
What Other Holes Mean (And Why They're Concerning)
Apart from the mouth and the two ear openings, any other holes or unusual indentations on a bearded dragon's head are generally not natural and should be a cause for concern. These can be indicators of underlying health problems that require prompt veterinary attention.
Potential causes for abnormal holes or lesions on a bearded dragon's head include:
- Abscesses or Infections: These are often pockets of pus caused by bacterial infections, which can sometimes rupture and leave an open wound.
- Injuries: Traumatic incidents, such as bites from cage mates, scrapes, or impacts with tank decorations, can result in open wounds.
- Parasitic Lesions: External parasites, though less common on the head, could cause skin irritation and potential lesions.
- Skin Conditions: Certain fungal or bacterial skin infections might manifest as unusual lesions or openings.
If you observe any unidentifiable holes, swelling, or discharge on your bearded dragon's head, it is crucial to consult with a qualified exotic veterinarian immediately. Early diagnosis and treatment can significantly improve the outcome for your pet.
