FACTS

The Crested Gecko sleeps in the day and is active at night.
The Crested Gecko or eyelash gecko is a species of gecko native to southern New Caledonia. In 1866, the crested gecko was described by a French zoologist named Alphone Guichenot. This species was thought extinct until it was rediscovered in 1994 during an expedition led by Robert Seipp. 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.
The Crested Gecko is also known as the eyelash gecko because of the crest of skin over its eyes that resembles eyelashes and due to this, the crested gecko is often referred to as the eyelash gecko.
They lack eyelids to clean their eyes so, geckos uses their long tongue to moisten their eyes.
The crested gecko earns its name because of the hair-like projection that runs from above the eye to the base of the tail.
