Are hoop snakes dangerous?

What you might have heard: Hoop snakes are dangerous snakes. When surprised one of these snakes will grab its tail in its mouth, form a "hoop" with its body, and roll away. One version of the myth says that the hoop snake will chase a person in this manner, but a conflicting version says that the hoop snake uses this means to escape from a threat. Yet another version has it that the snake will roll down a hill killing anything and everything in its path.

The REAL story: There is no such thing as a hoop snake. You won't find one in a zoo, you won't find one in a museum. And you won't find a record of a hoop snake observation that has been verified by an independent, second observation.
