Geckos (Gekkonidae family of Lizards)
|
The Gekkonidae family forms part of the Lizard sub-order (Sauria). Geckos are small, nocturnal and soft-skinned and are easily recognised by their large unblinking eyes. These eyes are lidless, protected by a clear covering that Geckos lick clean with their lengthy tongues (Wilson and Swan, 2003).
Geckos are closely connected with legless (flap-footed) lizards and there is significant argument that they should in fact be the same family. In Australia, there are over 110 species of Geckos, two of which has been included here so far.

MARBLED (SOUTHERN) GECKO
|
| | Christinus marmoratus
| The Marbled Gecko is found along the south coast of Australia and is a colourful small lizard growing to a maximum length of around 12cm (5in) in length.
This specimen was found in Melbourne and kept by our staffer Ben for a week on a diet of baby crickets before being re-released. The strength of the 'marbled' colours changes with activity and heat and care needs to be taken to prevent fat loss and tail-shedding from shock.
