This is an introduced species in Hong Kong, and they can be found on the palm trees around Disney land, probably brought in hiding in the canopies of those trees. I have seen them wild in Thailand. This is a type of oriental garden lizard, but unlike many other lizards, they do not drop their tails, and their tails can be very long, stiff, and pointy.
