Bearded Dragon from Central Australia

The Central Bearded Dragon (Pogona vitticeps), also known as the Inner Bearded Dragon, is a type of Agamide Lizards living in a wide range of arid and semi-solid regions of Eastern and Central Australia. This is the most popular home reptile, which is often exhibited in zoos.

Adults of this species can achieve a total length of up to 60 cm (24 inches), while the tail is more than half. There is some sexual dimorphism: males can be distinguished from females on a wider cloque hole, a wider base of the tail, a larger head and beard, as well as the possession of hemiphenes. The males also have more pronounced femoral pores than females (they can be seen in the form of wax tubercles on the underside of the rear legs). Bearded Dragons are widely vary in colour, including brown, reddish brown, red, yellow, white and orange. They are able to undergo moderate changes in the shade of their colors to help the scaway along both sides of the throat, neck and heads to form many narrow spikes that descend on the sides of the body to the tail. Feeling the threat, the bearded dragon is molded on Earth, sticks out a barbed throat and reveals the mouth to seem more. Bearded dragon is named so because of the bag-shaped protrusion (also called the gentle bag) on ​​the lower side of the neck and chin, which usually becomes darker than the rest of the body. It also boasts spiny protrusions. Both of these characteristics are similar to the human beard. The males usually have a darker “beard” than females, and during the marriage season and courting it usually darkens almost black. Bearded dragon, like most Agamid lizards, has strong legs that allow him to completely tear off her body from the ground while driving. This is done in order to reduce the heat coming from the Earth, as well as to increase the stream of air above the stomach so that it is even more cooled.

The study conducted in 2014 has established the existence of endogenous circadian rhythm in changes in Pogona vitticeps pigmentation. When exposed to light, spinal leather lizard becomes darker, and when exposed to darkness – lighter. In conditions of constant darkness (i.e. subjective night), the spinal leather lizards becomes the brightest.

Central Australia

Pogona vitticeps is native to the semiarid woodland, arid woodland, and rocky desert regions of Central Australia. They are skilled climbers and often spend just as much time perching on tree limbs, fence posts, and in bushes as they do on the ground. They spend the morning and early evening sunning themselves on exposed branches or rocks, and retreat to shady areas or burrows during the hottest parts of the afternoon.

Bearded Dragons do not vocalize, except to hiss softly when threatened. Instead, they communicate through colour displays, posture, and physical gestures, such as arm waving and head bobbing. Bearded dragons are not social animals, but will sometimes gather in groups, especially in popular feeding or basking areas. At these times, a distinct hierarchy will emerge: the highest-ranking animals will take the best – usually the highest or sunniest – basking spots, and all other individuals arrange themselves lower down. If a low-ranking animal tries to challenge one of the dominant dragons, the dominant animal will demonstrate its superiority by bobbing its head and inflating its beard, at which point the challenger may signal submission by waving one of its arms in a slow or fast circle. If the low-ranking dragon does not submit, it will return the head bob, and a standoff or fight may ensue.
