This is one of my reptile/amphibian images from the IFC contest. This was from my blind on the stock tank. I had 4 different ribbon snakes hunting tadpoles in the tank.

This one is spectacular, Robert. Just the snake would have been an excellent image, but all the duckweed covering the snake's head puts this one way over the top for me.
