The crested gecko, New Caledonian crested gecko, Guichenot's giant gecko or eyelash gecko, Correlophus ciliatus, is a species of gecko native to southern New Caledonia. This species was thought extinct until it was rediscovered in 1994. Along with several Rhacodactylus species, it is being considered for protected status by the Convention on the International Trade in Endangered Species of Wild Flora and Fauna. It is popular in the pet trade.
e crested gecko has hair-like projections found above the eyes, resembling eyelashes. It has a wedge shaped head and a crest that runs from each eye to the tail. Crested geckos do not have eyelids and so they use their long tongues to moisten their eyes and remove debris. The toes and the tip of the semi-prehensile tail are covered in small hairs called setae. Each seta is divided into hundreds of smaller (approximately 200 nanometres in diameter) hairs called spatulae. It is believed these structures exploit the weak van der Waals force to help the gecko climb on most solid surfaces. The toes have small claws which aid in climbing surfaces to which their toes cannot cling. They possess a prehensile tail which they use to assist in climbing. The tail can be shed as a deterent to predators. Unlike some other geckos once they lose their tail it will not grow back, however this is not as harmful to the gecko as it is to others, such as the Leopard gecko.
The crested gecko is 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.
