NORTHERN BLUETONGUE Tiliqua intermedia Mitchell, 1950
The Northern Bluetongue grows to 60cm and is found throughout tropical parts of northern Australia. It is closely related to the Eastern Bluetongue Tiliqua scincoides with which it has been confused for many years. The Northern Bluetongue Tiliqua intemedia occurs in various habitats, but is most common in Savannah woodland.
It is diurnal and feeds on smaller animals and arthropods, as well as various plant material. It shelters under various types of ground cover, but is particularly fond of sheets of tin commonly found around human habitation.
When disturbed it will stand its ground, puff up its body, open its mouth, and flick its blue tongue.
Females give birth to five to twenty live young during the wet season.
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.
