Leatherback Bearded Dragons for sale in the UK
- Leatherback — do not pair with another Leatherback. Offspring of that pairing carry a hereditary defect and cannot be sold here.
About the Leatherback gene
Leatherback takes the raised scaling off a bearded dragon's back and leaves the skin smooth. That is why nearly every serious colour project runs through it: with no raised scale breaking the pigment up, whatever colour sits underneath reads cleaner and more saturated.
Appearance
The back and tail carry small, uniform, low-profile scales in place of the usual rough spiking, and the legs lose most of their spikes too. What stays is the tell: one row of spikes down each flank, with the beard and head spikes intact. That retained row is the cue worth trusting, because a Silkback loses the flank row as well and a normal is spiked across the whole dorsum. Out of the same line, colour reads more vivid on a Leatherback than on a normally scaled animal. Animals vary: some keep small residual dorsal bumps that read as enlarged scales rather than true spikes.
Genetics
Incomplete dominant, which most of the hobby still writes as co-dom. A Leatherback is a visual heterozygote, and the alias carried alongside it is Het Silkback. Two copies give the super form, Silkback, also called a silkie or a scaleless, which has its own catalogue row here. Two incomplete dominant lines circulate, Italian Leatherback and American Leatherback, the latter also sold as American Smoothie, and they are compatible: pair across the two and you get Silkbacks. A separate recessive smooth-scale trait, Phantom Leather, first produced in 2004 by Phantom Dragons Inc, looks similar and cannot make a Silkback. One copy of the incomplete dominant gene over homozygous Phantom Leather is what the hobby sells as Microleather or Microscale.
Known issues
Do not pair a Leatherback with another Leatherback. That pairing makes Silkbacks, and a Silkback cannot be listed or sold on Bask: it is scaleless, so it needs more care than a scaled animal - higher humidity, softer surroundings, and closer attention to shedding, skin and hydration. The concern is the two-copy animal. Pairing a Leatherback to a normally scaled dragon produces Leatherbacks and normals and no Silkbacks at all.
The single-copy animal is not wholly clear of it, which matters to anyone buying breeding stock. Sakich and Tattersall (2021, Journal of Experimental Biology) measured evaporative water loss across the three phenotypes: Silkbacks lost water at roughly twice the wild-type rate, and Leatherbacks sat closer to the Silkbacks than to the wild-types, with no matching shift in thermal preference to compensate. A 2024 veterinary review by Latney names scalation selection in bearded dragons as a phenotype-selective welfare problem on the same grounds.
