Flying lizard

The so-called 'flying' lizard has a web between its front and back pairs of legs which enable it to glide between the branches of the trees where it lives. I guess it enables it to get to its food quickly and escape predators in a hurry when needed. While gliding it steers with the flap below its head - it act like a rudder. Taken with a K10D and Sigma 50-500 in my garden on Sulawesi, Indonesia.
