Caiman head

We will transition from the photos of a poison reptile during the last two days to another reptile. This is a close up of the head of a caiman. I apologize that the photo is not sharper, but he was lurking in a shadowy area of a river in a dark area of the jungle. You can see the vertical slit of his eyes.

He was very still, lurking below the water's surface, waiting for a bird or other prey to come near.
