The common gliding lizard

 From a distance it looked like any ordinary house lizard.  I thought I just get a shot of it since it was found crawling up a tree at the Botanic Island Two.  After transferring the picture into the computer I saw something interesting.  Zooming in at the image I was taken aback.  It was in fact a gliding lizard (Draco sumatranus) which I have seen in many occasions  gliding from one branch to another tree or branch at the park.  On closer viewing I found another interesting feature.  The camera caught the lizard's 'gular fold' which is a triangular flap or skin under the chin.  This special feature is used to communicate with other lizards, mostly for mating purposes.
