Here is a picture I took in Cancun Mexico last October.
I was walking along the beach and this Iguana ran out from under one of the sunbeds and rather frightened me (because I was not expecting him).
I crouched down and took the picture quickly before he ran off.
I am particulalry pleased with it because it fits the frame so well (it has not been cropped or editied). The shaodw of his face on the left, and the end of his tail on the right, are both in picture, which was fairly lucky as I had to take it so quickly.
