Hidden Fish Head

I was snapping away, taking pictures of a creek bed with the flowing water and patterns on the bed.  Only later, when looking closely at the results did I see this image with the blue/purple image of a fish head poking out from the left side (well, sort of.... one has to slip a bit back into childhood and awaken the imagination that used to find various identifiable objects formed by clouds in the sky--only this is on a creek bed with colors and not in the sky with clouds).  The more I look, the more it seems like the fish has its mouth open and is swallowing a worm.  What do you see?
