If a snake wraps itself around any part of your body-sepecially ankle area-what is the best defense if you are in water-mainly shallow?

Well honestly it depends on the size of the snake and the species and weather or not they are venomous or not.

Run and use any thing necessary if your not close to your house try to find something that could kill it

If it's at your house use some type of sharp everyday house tools and stab it. If not at you house try to find a nearby object to use against it or you can run and hide

Get out of the water fast and run some where safe
