On Saturday, about lunchtime, the sun was shining strongly, and a silly Eastern Blue-tongued Lizard (Tiliqua scincoides scincoides) was lying in the middle of the bitumen road just beyond Carrington Falls. Naturally I stopped, and urged it to get off the road, where it would almost certainly have been run over. (Squashed Blue-tongues are an all too common sight around Robertson in November.)
I also took the opportunity to take some photographs, as the Lizard was not in a hurry to go anywhere.
Note the backward pointing position of the legs of this lizard (see below for detail). It is the same pose as I observed with a Water Dragon, several weeks ago. It must be a "lizard thing". It seems odd to me, a human, who is more familiar with the posture used by mammals such as cats and dogs. I would expect them to lie with legs poised ready to "push off". But two specimens of very different lizard species, in two weeks, were lying with their legs in just this position. Maybe our local lizards are very "laid back".
I also wondered if this lizard's tail had re-grown. It seems to be very different in texture from the body of the lizard - much duller. I do not know if this is normal, or not. I have checked the Museum Victoria Bioinformatics site on Victorian Lizards. They had several sub-species of Blue-tongues, but all had more evenly matched tail and body colouring than this specimen. The specimen linked here is closest to the Lizard in these photographs.
I was expecting that it would hiss at me (as they are supposed to do), but this one did not. I wanted to photograph its tongue (of course). It started to move off through the grass, flicking its tongue very rapidly, but infrequently (i.e., a quick flick of the tongue, every now and then). It took me quite some time, and lots of shots to get one fully exposed tongue shot.The surprise for me was that the tongue was nearly all pink, with a blue band, or should I say blue dots on either side of the tongue, in a prominent position just behind the tip.
By contrast, here is the tongue of another Blue-tongue which I came across down on Tourist Road, Kangaloon, back in February 2007. Its tongue was fully blue, with a strong bright blue colour.I wonder if this is an individual difference, age difference (though both specimens were fully grown), or a sexual distinction? I do not know. Any advice from experienced Lizard wranglers would be appreciated.
