The Crested Gecko, New Caledonian Crested Gecko, Guichenot's Giant Gecko or Eyelash Gecko, [Correlophus Ciliatus] is a species of gecko endemic to South Province, New Caledonia. There are three disjunct populations, one found on the Isle of Pines and surrounding islets, and there are two populations found on the main island of Grande Terre. One population is around the Blue River, which is a protected provincial park, and the other is further north, just south of Mount Dzumac. This species was thought extinct until it was rediscovered in 1994.
      The species was first described in 1866 as Correlophus ciliatus by the French zoologist Alphone Guichenot in an article entitled "Notice sur un nouveau genre de sauriens de la famille des geckotiens du Muséum de Paris" ("Notes on a new species of lizard in the gecko family") in the Mémoires de la Société Scientifique Naturelle de Chérbourg.
       The Crested Gecko has many naturally occurring color groups, some of which include: grey, brown, red, orange, and yellow of various shades. They have variable markings, which include spots, pinstripes, tiger-like stripes etc etc. The markings and coloration are not geographic indicators; offspring of the same pairings may display differing coloration and markings. The Crested Gecko has a distinct head shape and crest abundance. Geckos with a head length less than 1.3 times its width are considered "crowned" Crested Geckos.​
