ok the kids found this in the pool today. I took two pictures of it… I am sure it isn’t venomous… and even though it bears resemblance to a ring snake I know it isnt because the spot on the snake is on the HEAD not around the neck. It’s about 2 inches long, dark brown and light on the belly, with that white diamond on it’s head. I looked up worm snakes, king snakes, water snakes… I can’t figure it out. anyone?
