Extreme Harlequin
Morph
In crested gecko breeding, extreme harlequin refers to a high-pattern visual morph of Correlophus ciliatus, the arboreal gecko from New Caledonia widely kept in reptile collections. The label describes coverage rather than a separate species or formal breed. Compared with a standard harlequin, an extreme harlequin shows more cream, yellow, orange, or white markings across the flanks, limbs, and sometimes the lower sides, usually over a darker red, brown, olive, or near-black base. Strong examples look bold when fired up, although the same animal may appear softer and less contrasty while resting.
Care does not differ from other crested geckos: a tall enclosure with branches and cover, moderate temperatures, nightly humidity that dries back out, and a complete crested gecko diet with occasional insects. The morph matters most in buying and breeding. Extreme harlequin is largely line-bred and polygenic, so two highly patterned parents can still produce a range of hatchlings. Parent photos, fired-up and fired-down pictures, and clear lineage notes are more useful than the label alone.
