They like to climb on branches. They also sit on rocks in the sun. They sleep at night.

They eat plants and bugs. They can live for many years.

These lizards are very interesting!

Bearded dragons are special lizards from Australia.

They live in many places like deserts and shrublands. These lizards spend much of their time climbing. They are semiarboreal, which means they live partly in trees. They like to climb on branches or rocks.

This helps them bask in the sun. They are diurnal, so they are active during the day. At night, they sleep in holes or tree cracks.

These lizards have bumpy, spiny scales. They have a dark area under their throat called a beard. They puff this beard out to look scary. This helps them fight off predators. They also use their beards to talk to other dragons.

A dragon might bob its head to show it is the boss. A smaller dragon might wave its arms to show it is not a threat.

Bearded dragons eat plants and bugs. They can change color to help stay warm. Some dragons go into brumation. This is a type of sleep where they do not eat for months. They still drink water during this time.

Many people keep them as pets.

Bearded dragons are amazing lizards from the genus Pogona.

They belong to a group called Agamidae. These reptiles are famous for the area under their throats. This part is called a beard. They can puff this beard out to look much larger. The beard can also turn jet black. This helps them look scary to predators. It also helps them talk to other dragons. They are semiarboreal, which means they spend much time in trees or bushes.

They are also diurnal, so they are active during the day.

These lizards use many signals to communicate. A dominant male might bob his head up and down. This shows he is the boss of his area. Smaller dragons often wave their arms to show submission. This tells the bigger dragon they are not a threat.

They also use their color to manage heat. A dragon might turn black to absorb more warmth from the sun. When it gets very hot, they will burrow underground to stay cool. During cooler times, they go into a state called brumation. This is like a long sleep where they do not eat for months. They still drink water while they rest.

Scientists have studied these lizards for a long time. They live in many parts of Australia. Their home includes deserts, woodlands, and even coastal dunes.

They can be found in the eastern states and South Australia. They also live in the southeastern Northern Territory. Some species like the central bearded dragon are very common. The genus includes six recognized species. These include the eastern, western, and Kimberley bearded dragons. Each one has its own special place in the wild.

Bearded dragons have some very interesting physical facts. Adult males can grow much longer than females.

They have broad, triangular heads and flattened bodies. Their skin is covered in rows of spiny scales. These spikes make them look more dangerous to enemies. They also have a special way to resist certain snake toxins. This is due to something called selective evolution. In the wild, they eat plants and insects. In homes, they can live for 10 to 15 years. Some have even lived to be 18 years old.

Many people around the world enjoy these lizards as pets.

They were brought to the United States in the 1990s. Even though Australia banned selling wildlife in the 1960s, they remain popular. Because of selective breeding, pet dragons come in many colors. They can be dark brown or even completely white. They are very different from the dragons in fairy tales. These real dragons are smart enough to understand illusions. For example, they know a larger plate does not always mean more food.

The genus Pogona consists of eight lizard species commonly known as bearded dragons.

These reptiles belong to the subfamily Amphibolurinae within the Agamidae family. They are famous for the skin on the underside of their throats. This area, called a beard, can be inflated and turned jet black. Bearded dragons use this feature for various social and survival reasons. They most often use it when they feel stressed or threatened. They also use the beard to entice a mate during courtship.

Bearded dragons possess several distinct physical characteristics. They have broad, triangular heads and flattened bodies. Their entire bodies are covered in clusters of spiny scales. These spikes help them appear more dangerous to potential predators. When a dragon feels threatened, it will puff up its body. This makes the spikes look even larger and more intimidating. They also use a behavior called gaping, where they open their mouths wide. These physical actions work together to defend the lizard from danger.

Communication in bearded dragons involves specific gestures and visual signals. Adult lizards are very territorial and use displays to manage social interactions. A dominant male will perform a head-bobbing display. This involves moving the head up and down quickly. Males also use this behavior to impress females during mating rituals. To show submission, smaller dragons will perform a hand-waving gesture. This tells a larger dragon that they are not a threat.

Females also use arm waving and lowering their bodies to avoid aggression from dominant males.

These lizards are semiarboreal, meaning they spend much time in trees or bushes. They are also diurnal, so they are active during the daylight hours. In the mornings and afternoons, they bask on rocks or exposed branches. At night, they seek shelter by digging holes or climbing into tree crevices. They inhabit many environments across Australia, including deserts, shrublands, and coastal dunes. Their range extends from the eastern states to the eastern half of South Australia. They also live in the southeastern Northern Territory.

Bearded dragons undergo a period of dormancy called brumation. This process is similar to hibernation but has specific differences. During brumation, reptiles may go months without eating. However, they will still drink water sporadically during this time. Brumation occurs when temperatures drop below certain levels. Specifically, night temperatures must fall between 15.5 and 21.0 °C. During the day, temperatures must be between 24.0 and 26.5 °C for 8 to 10 hours. This state allows them to survive when the climate is not ideal for activity.

Reproduction in this genus involves complex biological processes. Females can store sperm in structures called oviductal crypts. This allows a female to lay a clutch of 11 to 30 eggs from a single mating. They also exhibit temperature sex determination during embryo development. This means the temperature of the environment influences the sex of the offspring. High incubation temperatures, up to 36 °C, can cause sex reversal. This results in a female that has a male genotype.

This unique biological mechanism shows how closely tied these lizards are to their environment.

In the pet industry, bearded dragons are highly popular. The central bearded dragon is the most common species kept in captivity. They were introduced to the United States in the 1990s. Through selective breeding, humans have created many different colors and patterns. Some dragons can even be bred to be completely white.

In a controlled environment, captive adults can live for 10 to 15 years. The current world record for a captive bearded dragon is 18 years. They are also noted for their intelligence. Experiments have shown they can perceive the Delboeuf illusion. This means they understand that a larger plate does not always hold more food.
