The natural habitat of the crested gecko is on the islands of New Caledonia, located about halfway between Australia and Fiji. This humid tropical island is the only place they are naturally found. They are, however, popular in the reptile hobby and captive-bred specimens can be found throughout the world.
The largest crested geckos can grow up to 17 inches in length, while smaller crested geckos range in maximum length from 8 to 10 inches. They are omnivores, eating both animals and plant material. Nocturnal creatures, all crested gecko species are also arboreal, spending most of their lives up in trees.
The crested gecko’s popularity probably has a lot to do with its distinctive appearance. Their most notable features are their namesake crests, ridges of skin edged with pointy scales that begin above the eye and continue down the crown of the head and onto the back of the neck. These crests may be part of the crested gecko’s defense system by causing them to appear too unappetizing for potential predators to bother with.
