Unlock the Secrets of Your Bearded Dragon’s Anatomy & Biology
Welcome to the fascinating world of bearded dragon anatomy and biology!
Their unique anatomy holds the secrets to their behavior, care needs, and even communication. From their extraordinary “third eye” to the intricate network of femoral pores on their legs, each feature tells a story of survival and adaptation.
This guide unravels mysteries, answer questions, and equips you to meet your bearded dragon’s needs like a pro.
1. Male or Female? How to Tell
One of the first things you may want to check is whether you have a female or male bearded dragon. I can’t tell you how many times I have see a new pet owner exclaim “my boy just laid eggs!”.
Figuring out their gender might seem challenging at first, but you will get the hang of it quickly.
Why It Matters: Understanding your bearded dragon’s gender is essential for:
- Managing potential breeding behaviors.
- Tailoring their care needs, as males and females may have slightly different health risks.
How to Identify Gender: There are two main methods to identify a bearded dragon’s gender:
-
Femoral Pores:
- Males have larger, more pronounced femoral pores on the underside of their thighs, used for scent marking.
- Females, on the other hand, have smaller or less visible pores.
-
Hemipenal Bulges:
- Gently lift your bearded dragon’s tail (only when they’re calm and relaxed). Males typically show two distinct bulges near the base of the tail, while females have a smoother appearance.
Still unsure how to tell if your bearded dragon is a boy or a girl? Still can’t tell? That’s okay! Some bearded dragons are trickier to identify until they mature. Here is a guide on how to tell whether you have a female or male bearded dragon.
2. The Third Eye: A Bearded Dragon Superpower
Yes, your bearded dragon has a “third eye.” This is not a myth—it’s called the parietal eye, it’s located right on the top of their head and is a key feature of the bearded dragons anatomy.
What Is the Third Eye? The parietal eye is a small, light-sensitive patch of skin connected to the brain. Unlike their regular eyes, this “eye” doesn’t see images but instead detects changes in light and shadows.
Why Is a Bearded Dragons Third Eye Important?
- Survival Mechanism: In the wild, the third eye helps detect predators overhead, giving them time to flee.
- Behavioral Impact: It influences basking habits, as bearded dragons use it to monitor sunlight exposure and stay warm.
Caring for the Third Eye
- Protect their habitat from bright, flashing lights or sudden shadows, which may stress them out.
- Ensure the top of their head is clean and free of debris, as this area is sensitive.

Femoral Pores: Secrets Revealed and How to Care
Femoral pores are one of the most fascinating and perhaps even misunderstood features of the bearded dragon anatomy. These tiny openings along the underside of their thighs play a crucial role in their lives.
What Are Femoral Pores? Femoral pores are small, dot-like structures that secrete a waxy substance. They are more prominent in males and are used for:
- Marking Territory: Males use femoral pore secretions to establish dominance and claim their space.
- Mating Signals: These secretions also play a role in attracting mates.
Why They Matter to You: Femoral pores can become clogged or infected if not properly maintained, leading to discomfort or health issues.
Here’s how you can help your bearded dragon have healthy femoral pores:
- Check the pores: Check the pores during your usual health inspections. They should look clear and clean.
- Provide rough surfaces: Your bearded dragon needs rough surfaces like rocks and branches to help naturally clear any buildup.
- Occassional baths help soften the residue: Offer warm baths occasionally to soften and clean the area.
- Avoid picking: Don’t try to manually clear clogged pores. Provide the right environment and let your bearded dragon do what it knows how to deal with.
There is so much to know about your bearded dragons femoral pores and the secrets that they tell.
Bearded Dragon Teeth: Anatomy and Care
Caring for your bearded dragons teeth is important.
Bearded Dragons have two types of teeth: Bearded dragons have mostly acrodont teeth but they also have a few pleurodont teeth at the front. Let’s look at what that means to them.
-
The Acrodont teeth are fused to the jawbone: Imagine teeth that are glued directly to the jawbone. That’s what these are. Chameleons are another lizard that has acrodont teeth.
- They’re great for chewing tough food, like leafy greens or hard-shelled insects.
- But here’s the catch: if these teeth are damaged, they don’t grow back. So, they need to last a lifetime.
-
Bearded dragons have Pleurodont teeth at the front which are replaceable: Now, at the front of the mouth, bearded dragons have teeth that can be replaced. Other lizards that have pleurodont teeth are anoles, geckos and iguanids.
- These teeth are attached to the jaw more loosely, kind of like a tree planted in soil instead of glued down.
- They’re handy for grabbing and holding food, like a cricket hopping by.
Signs of Dental Problems: Be on the lookout for:
- Discolored Teeth: Yellow or brown teeth may indicate poor hygiene or infection.
- Swollen Gums: This could be a sign of gum disease.
- Difficulty Eating: If your bearded dragon avoids food or shows discomfort, it might have a dental issue.
Tips for Maintaining Healthy Teeth:
- Balanced Diet: Feed your bearded dragon a mix of crunchy vegetables and insects to help keep their teeth clean.
- Regular Inspections: Check their mouth regularly for any signs of plaque, decay, or swelling.
- Vet Visits: Include dental check-ups during routine visits to your veterinarian.
Fun Fact: Did you know? Baby bearded dragons are born with tiny teeth, fully equipped to start eating small insects and soft vegetation right away!
Here is the complete guide to bearded dragon teeth and how to care for them.
How Big Do Bearded Dragons Get?
Bearded dragons start off small and adorable (we can be bias :)), and grow into impressive lizards with proper care.
Their average size and weight depends on species and care and its all broken down for you in the bearded dragon ultimate size and weight guide here. A fully grown adult Central and Eastern bearded dragon can measure between 14.8–26.6 cm (5.83–10.47 in) whereas a Western bearded dragon will reach around 9.7–12.9 cm (3.85–5.08 in) snout to vent length.
What influences how big a bearded dragon grows?
- Quality of their diet: A balanced diet of proteins, greens, and calcium ensures steady, healthy growth.
- Habitat conditions: Proper lighting, temperature, and space promote optimal development.
- Medical care: Having a vet be able to jump in when something goes wrong can also elongate a beardies life.
- Genetics: Some bearded dragons naturally grow larger due to their lineage.
How to track growth:
- Use a growth chart to record their length and weight monthly.
- Watch for signs of stunted growth, such as lack of appetite or underdeveloped limbs, which may indicate improper care. When bearded dragons are kept together as they grow this can be quite a risk, one often outgrows the other.
Bearded Dragon Skin: Shedding and Coloration
A bearded dragon’s skin plays an important role in their survival and communication. From shedding to color changes, their skin reveals a lot about their health and mood.
Why do bearded dragons shed? Shedding, or ecdysis, occurs as bearded dragons grow. Hatchlings and juveniles shed frequently, while adults shed less often, usually in patches.
How you can help your bearded dragon through shedding:
- Provide Humidity: While their environment should be dry, a humid hide or a warm bath during shedding can help loosen skin.
- Do Not Peel: Let the skin come off naturally to avoid causing injury or stress.
- Watch for Problems: Retained shed, especially around toes or the tail, can lead to constriction and circulation issues.
The meaning of the different coloration:
- Stress or Fear: Darkened skin, especially on their beard, often signals stress or discomfort.
- Temperature Regulation: Bearded dragons may darken their skin to absorb more heat or lighten it to stay cool.
- Mating Signals: Vibrant colors, especially in males, may appear during mating season.

Understanding Bearded Dragon Reproduction: From Courtship to Hatchlings
Breeding bearded dragons is a natural aspect of their biology that highlights their fascinating reproductive behaviors and physiology. Understanding the reproductive process if you want to breed can be both interested in breeding and important for the care of the breeding beardies and their offspring.
The reproduction cycle from courtship to clutches of eggs:
-
Courtship Behaviors: Male bearded dragons use head bobbing, beard darkening, and territorial displays to attract females. These behaviors, which are common among lizards, are particularly observable in bearded dragons, serving as a way to initiate mating and establish dominance.
-
Femoral Pores and Mating: Both male and female bearded dragons have femoral pores on the undersides of their thighs. Males produce waxy secretions during the breeding season, which may help in marking territory and signaling readiness to mate. These pores are a common feature in lizards but play a crucial role in breeding behavior.
-
Egg Laying and Sperm Retention: Female bearded dragons can lay multiple clutches of up to 35 eggs (Amey and Whittier, 1999) after a single mating, thanks to their ability to retain sperm for weeks or months. This reproductive strategy is shared by many reptiles and helps ensure successful reproduction in challenging environments.
-
Hatchling Development: Hatchlings emerge after 50-70 days of incubation, fully equipped for independent survival. This adaptation, common in oviparous reptiles, ensures their ability to thrive from the moment they hatch.
Why this cycle matters to you: Once you know the reproductive behaviors and processes you can help your bearded dragons:
- Recognize signs of courtship.
- Provide the right equipment to the female for laying eggs.
- Take the eggs through their cycle to hatching.
- Looking after the hatchlings.
