Vitticeps plant

This interesting lizard is found only on the Australian continent. Although its appearance may be disconcerting, it is actually a completely harmless animal to humans. It is an excellent climber, so it is found both on land and on rock formations, trees and shrubs. This is a popular reptile kept in terrariums.

1

The bearded dragon is a lizard from the agamidae family.

There are about 350 species of agamids, divided into 50 genera.
2

Inhabits rocky deserts, semi-deserts and forests of central Australia.

3

They can be found both on the ground and on tree branches, rocks, fence posts and bushes.

They are most often seen in the morning or late evening, as too high temperatures drive them into shaded areas or burrows.
4

The body length of a bearded dragon can reach a maximum of 60 cm.

More than half of this length is the tail. Normal adult weight ranges from 280 to 510 g.
5

Individual individuals may have different skin colors.

It is most often a mixture of brown, russet, red, yellow, white and orange. Their body is covered with scales and their triangular shaped head is covered with spines used to repel attackers. Despite their pointed appearance, these spines are quite flexible and are not capable of stinging.
6

They can change the color of their skin slightly for communication purposes.

They do this by changing the pigment present in their skin in organelles called chromatophores.
7

Sexual dimorphism is difficult to determine.

The sexes can be distinguished by a wider cloacal opening in males, a thicker tail base, and a larger head and chin. The coloring of males is also less intense than that of females. They also have a hemipenis, a copulatory organ found in male squamate reptiles (snakes, amphibians and lizards).
8

Bearded dragons are omnivores, although their diet changes as they age.

Young animals often eat meat, and as they grow older, they choose more plant foods. They feed on beetles, mealworms, spiders and moths, and the most common plants of choice are vegetables and flowers.
9

They are solitary, although sometimes they can be found in groups.

Agamas live in large groups in places with abundant food or good sunlight, where they come to bask.
10

When they are grouped together, their hierarchical structure becomes visible.

For example, in swimming areas, high-ranking individuals occupy the highest and most illuminated places.
11

When a lizard with a lower status in the group tries to take a higher place in the hierarchy, the higher status individual will extend its chin and nod its head.

If the opponent wants to give way, he makes circular movements with one of his front paws.
12

They usually walk on four legs, but can run on two.

They do this when they feel threatened or are chasing prey. Adults can run at a speed of 14 km/h.
13

Agamas do not make any sounds except hissing, which is used to scare them away.

They use color changes, movements and gestures to communicate.
14

The reproductive period occurs in early spring.

At this time, males become very aggressive towards each other and fight for dominance.
15

The female lays 11 to 30 eggs in a shallow nest dug in the sand.

The eggs are left unattended and after about 2 - 2,5 months the young hatch from them. The duration of incubation is, of course, determined by the ambient temperature: the higher it is, the faster hatching will occur.
16

Ambient temperature can influence the sex of hatched lizards.

At temperatures above 32°C, some males may hatch into females. Despite having two male chromosomes (ZZ), they are quite capable of reproduction and sometimes lay even more eggs than genetic females (ZW).
17

Young females with ZZ chromosomes resemble males, but as they mature, they become similar to females with ZW chromosomes.

Their heads are not as massive as those of males, and their jaws do not have such a strong grip.
18

Bearded dragons can live up to 20 years in captivity.

The average lifespan of these lizards in the wild is about 11 years.
19

Bearded dragons are readily kept by breeders.

Most of the specimens now on the market are descended from ancestors that were illegally exported from Australia in the 70s. For proper development, they need a terrarium with a base size of 120 x 60 cm, equipped with a UVB lamp and a heating lamp. The temperature should be around 26°C.
