     GECKOES constitute a family of lizards remarkable for the large number of species it contains. They are also remarkable for a number of other features: for the readiness with which they have taken to living in houses, for their voices, the structure of their feet, the variation in the shape of the tail and for their eyes. […] As with the more familiar lizards, geckoes have the ability to cast the tail, and counts show that in some species two out of every five individuals have cast the tail and regenerated a new one.

     The marvelous ability of geckos to run down trees, surefooted and head first, was first noted by Aristotle over two thousand years ago. However, Aristotle was not able to see the tiny hairs, called setae, that cover the toes of geckos and empower this feat. The setae are part of an adhesive system that allows geckos to maneuver on a wide variety of substrates, to run upside-down, and to arrest their falls. Geckos can run vertically at over 1 m/s and can carry over twice their body weight up smooth, vertical surfaces.

The Golden-tailed Gecko is an invertebrate-eater and by night its adhesive toe pads allow it to prowl the branches of Brigalow trees with ease, looking for small insects and spiders to capture.
