These shots were taken within seconds of one another in the field in north-central Texas.  The juvenile PRAIRIE RATTLESNAKE Crotalus viridis viridis had reached 'stasis', leaving me free to take several shots.  Since I always take multiple shots, I tried to snap the second one too soon before my camera's flash had recharged fully.  That second shot, at right, was lit by only dappled sunlight, giving a somewhat pleasing effect demonstrating how cryptic an animal can be in nature - the way our eyes might perceive it as we walked by.  The first shot (left) is, of course, lighted more evenly and would be better in a field guide for identifying the specimen.
