Bearded Dragon (Zero Leatherback)

Bearded Dragon (Zero Leatherback)

Scientific Name: Pogona vitticepsCommon Name: Bearded Dragon (Zero Leatherback)

Species Overview

Size: Adults typically reach 18 to 22 inches (46 to 56 cm), with males slightly larger and broader-headed.

Appearance: Zero Leatherback Bearded Dragons combine two visual traits. Zero removes pattern and drastically reduces pigmentation when homozygous, producing an almost white or very pale appearance. Leatherback reduces dorsal scale prominence, creating a smoother, softer texture. The combination produces a dragon with pale coloration and smooth scales, while body structure and overall morphology remain standard.

Distribution: Native to the arid interior regions of central Australia.

Habitat: Wild Bearded Dragons inhabit dry scrublands, semi-desert plains, rocky outcrops, and open woodlands. In captivity, they thrive in spacious terrestrial enclosures with basking areas, climbing structures, and secure hides.

Behaviour: Bearded Dragons are diurnal, active, and alert. They display normal behaviours including basking, digging, climbing, arm-waving, and head-bobbing. Expression of Zero or Leatherback does not affect temperament.

Captive Care

Enclosure: Provide a terrestrial enclosure at least 48 inches24 inches24 inches (1206060 cm). Use a soilsand substrate mixture that is dry on top but deep enough to retain some moisture in the lower layers, supporting natural digging behaviour. Include basking platforms, hides, branches, rocks, and open floor space.

Temperature & Humidity:

• Basking area: 110 to 115F (43 to 46C)

• Warm side: 88 to 95F (31 to 35C)

• Cool side: 75 to 82F (24 to 28C)

• Night temperatures may drop to 68 to 72F (20 to 22C)

• Humidity should remain 3040%

Lighting: Provide strong full-spectrum lighting and high-output UVB (1012%) for 1214 hours daily. Proper UVB and heat gradients support calcium metabolism and natural behaviour.

Diet: Offer a varied omnivorous diet including crickets, roaches, silkworms, hornworms, black soldier fly larvae, leafy greens, vegetables, and occasional fruits. Juveniles require daily feeding; adults eat every 12 days. Use calcium and multivitamin supplements.

Behaviour in Captivity: These dragons are active, exploratory, and responsive. They bask, dig, climb, and display natural behaviours when provided with proper husbandry.

Special Considerations: Ensure proper UVB exposure, secure enclosure, substrate depth, and heat gradients. Overfeeding or insufficient lighting can lead to metabolic issues.

Taxonomy Note

The Bearded Dragon belongs to the genus Pogona, a group of Australian agamids adapted to arid environments. Pogona vitticeps is widely kept due to its hardy nature, manageable size, and engaging personality.

Genetics Note

Zero (recessive):Zero removes pattern and drastically reduces pigmentation when homozygous, producing an almost white or very pale appearance. This trait is visually expressed in this animal.

Leatherback (co-dominant):Leatherback reduces dorsal scale prominence, producing a smoother, softer texture. Expression varies with zygosity.

Genetic Combination Summary:This Bearded Dragon expresses Zero and Leatherback, producing a pale dragon with smooth dorsal scales. Each gene can be passed to offspring according to its inheritance pattern.
