6) Boa Constrictors

I know this sounds like a daft thing to say, but if a massive boa gets itself wrapped around you – don’t panic. I know, I know, good luck with that. It’s just that every time you breathe it will take the chance to wrap itself around you ever harder. So breath slow and steady.
Next step is to grab its tail, or somehow get it into your mouth without your hands. Bite down hard. They hate that. If you do manage to wrestle free a hand, punch it in the head. HARD. Preferably beat it with a rock. A snake doesn’t want to have to fight too hard for dinner, so hopefully it’ll give up.
