Playing Possum, Maybe?

A western mud snake (Farancia abacus reinhardti) looking for all the world like it's dead but not showing any obvious signs of damage. Some snakes feign death, but I don't know if this species does. They are normally nocturnal, so the fact that this one is beside a well-trodden hiking trail in the middle of the day suggests that it has indeed reached its sell-by date.
