Wikipedia:Leatherback bearded dragon

The leatherback bearded dragon, more commonly called the Italian leatherback bearded dragon, is a morph agamid lizard bred originally in Italy but are bred and sold around the world.

Description
The leatherback bearded dragon is one of the many morphs of bearded dragon found around the world, but what makes it stand out from the others is it's back being cleared of all spikes and scales and feels like horse leather. They grow up from 15 to 20 inches, tail in counting. Leatherback bearded dragons have more vivid and bright colors, and the removal of spikes help them bring out colors ranging from blood red to bright yellow. Like all bearded dragons, leatherbacks eat a variety of foods ranging from insects like cockroaches and mealworms, to vegetation such as lettuce. Leatherbacks mostly live from ages up from 7 and 12 years, but diseases may shorten their lifespan heavily. Leatherbacks are often considered one of the calmest bearded dragon morphs/species, since they don't attack humans nor other animals. However, studies have shown that these reptiles are aggressive to one another, and while this usually won't lead to fighting, it can cause stress in the dragon's environment. Leatherbacks are often seen flat as they lay on tree stumps or on the ground, but while moving around, they get in their natural body position.

Reproduction
Leatherback bearded dragons will, after 1-2 years presumably, start to mate. It takes a whole process, and the female might reject the advances. Unlike other bearded dragons, leatherback males won't attack each other, but will become aggressive over the female. In the process of courting the female, the male will circle the female, and it's beard (throat) will turn darker. If the female agrees and accepts, she will flatten her body, and the male will start biting the back and neck of the female. It will later get on top of her, and the cycle begins. However, they will only mate when it's in warmer tones of the year, such as late spring to early and mid summer. The female, with help from the male, will then create a burrow nest where she will lay three different clutches of up from 10-35 eggs and bury them to keep them warm. The eggs will hatch approximately three to four weeks after being put underground.

In captivity, it is common to have leatherbacks, as well as most other bearded dragons, mate after brumation season. Putting a nesting area of up to 15-20 inches in the cage is needed, as leatherback females will only lay eggs when she and her mate had dug a 10 inch hole.
