CENTRALIAN KNOB TAILED GECKO Nephrurus laevissimus Mertens, 1958
Distributed in inland parts of South Australia, the Northern Territory and Western Australia this gecko attains 13 cm. Like all 'Knob Tailed Geckoes' it is recognizable by the distinct round knob at the end of a short fat tail.
Restricted to spinifex Triodia sp., covered sand dunes and plains, where it lives by day in well concealed burrows.
This species feeds at night on small insects and other lizards. Although found in the hottest driest parts of the country this gecko has a relatively low tolerance for heat and dehydrates easily.
It is most active at temperatures lower than those which other desert species prefer.
The above was from the book Australian Reptiles and Frogs by Raymond Hoser and now available on a fantastic CD-Rom along with a vast amount of other information, papers and the like on reptiles, frogs and other wildlife.
