YAKKA SKINK Egernia rugosa De Vis, 1888
The Yakka Skink occurs in scattered localities throughout eastern Queensland. Attaining 45 cm this large skink is little known.
It lives in colonies often numbering 50 or more individuals, in sandy or rocky areas. When seen foraging during the day, this shy lizard will rapidly take to cover. The diet of this lizard consists of plant material, arthropods and other soft bodied animals. About two to five live young are produced, which are much more brightly coloured than the adults.

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.
