It is a small gecko, capable of growing to approximately 5 inches. They have toepads and small claws which allows them to climb almost any surface, such as a vertical brick face or even stick to glass. They are nocturnal and eat small insects.

Like most lizards, they eat insects which makes them quite beneficial.
