A real-life Ouroboros
The photo above shows a king snake that reportedly took its own tail into its mouth and couldn't egest it because the snakes teeth are pointed caudad to prevent prey from escaping. I was skeptical that perhaps this was a sham contrived episode, but it appears to have been real. The incident has has been posted on a variety of news sites and blogs, but curiously I haven't yet seen anyone note that this corresponds precisely with the mythical Ouroboros.
