This snake was photographed on 27/3 in the Greenhouse Bay on the UNCW campus. One feature of the snake that isn't very discernible in this picture is that its eyes are located on the sides of its head. This brings up the question of the role of vision in prey detection and capture. Since the snake doesn't have forward facing eyes it doesn't have the advantages of binocular vision when striking at prey. As a result the prey that the snake captures has to be relatively close to it since it doesn't have good depth perception. In addition the snake likely has round pupils and more cones than rods in its eyes since it's diurnal instead of nocturnal.
