water moccason in water

Nikon 5100 Nikkor 55-200 mm zoom lens f-5.6 ASA 1/400 ISO 200. The day was a bright sunny day which alowed for this photo to work out the snake was first on the bank and when he saw me he went into the water at first I had to wait til the mud settled to see hiim again and if you look closely in the middle of three plants you can see the pattern on his back he is coiled up on the bottom. The photo was taken in Clifton Texas not far from former President Bush's Ranch. It is the local swimming hole.
