A large Blue tongue Lizard has taken up residence in one of our old outdoor storage sheds.  He gave me quite a fright the other day when I nearly trod on him.  I obviously frightened him too, as I have never seen one display his tongue so readily.  I can see how it frightens preditors away, as the shock of the dark blue does give you a fright.  He was very co-operative to keep displaying his tongue after I ran back upstairs to fetch my camera.
