Geckos are the only reptiles that have the ability to use their voice (other than to make hissing sounds). They will often make barking, chirping or clicking noises when interacting socially with other geckos.
The smallest gecko (and in fact the smallest known reptile in the world), is the dwarf gecko – Jaragua sphaero. The adult dwarf gecko grows to only 3/4 of an inch in total length. This species is found in the Dominican Rebublic and on Beata Island in the Caribbean.
The Leaf Tailed Gecko of Madagascar has the distinction of having more teeth than any other lizard in the world.
The largest gecko is the Tokay (Gekko gecko). The Tokay is found anywhere between India and the Australian Archipelago. An odd characteristic of this lizard, is that you can see through it’s head by looking through it’s ears. Tokay geckos are aggresive and have been known to bite when provoked or threatened. The Tokay will eat rodents and small birds and even other lizards.
In Thailand, if you hear the cry of the Tokay Gecko (Gekko Gecko) seven times or more in a row, it will bring you good-luck.

A gecko is also considered to be a sign of good luck in Hawaii.
