The photo below is of an Eastern Blue Tongue (Tiliqua scincoides). I took the photo today as she was scurrying to hide behind the pot plant you can see top right (in the neighbour’s yard). At some point she must have been frightened and dropped her tail as a new, stumpier one has grown back.
Blue tongues are the largest member of the skink family (they can grow up to 60cm or 23″). They are quite common in Aussie gardens. I love them and hope we have one hiding somewhere.
The are perfectly harmless (although a fully grown one would probably leave a bruise if it bit you). If you get close they will hiss and poke out their tongue to scare you. Their tongue, like their name suggests, is blue.
Would you like one in your garden?
