Gecko is 5cm long
The endearing geckoes have a built in face washer – their tongues. Unlike many lizards, geckoes do not have moveable eyelids and rely on their tongues to keep their eyes free from grit and dust. More than sixty species of geckoes occur in Australia, most under 10cm in length, in a variety of habitats.
Some are brightly coloured but the majority have dull or mottled skin that merges in with the rocks and bark of their habitats. Some are tree dwellers; others hide during the day under bark or rocks, emerging at night to feed on insects.
Many have broad discs on their toes and fingers to make them agile climbers. As well as the novel use of their tongues, geckoes have another interesting adaptation – the ability to shed their tails if they are thereby seized by a predator.
