How to Survive an Anaconda Attack
According to the Peace Corps manual for volunteers who work in the Amazon jungle, here is how you survive an anaconda attack (edited for space).
1. Do not run. The snake is faster than you.
2. Lie flat on the ground, put your arms tight against your sides and your legs tight against each other.
3. Tuck your chin in.
4. The snake will begin to nudge and climb over your body.
5. Do not panic.
6. The snake will begin to swallow you feet first.
7. You must lie perfectly still. This will take a long time.
8. When the snake has reached your knees, reach down, take out your knife, slide it into the side of the snake’s mouth between the edge of its mouth and your leg. Quickly rip upward, severing the snake’s head.
9. Be sure you have your knife.
10. Be sure your knife is sharp.
Uhh… yeah, RUN. Anacondas are ambush predators, if they strike and miss, they can’t chase you down. They are semi-aquatic, and fairly slow on land.
Tucking in your limbs is just making it easier for the snake, if anything, sprawiling out and making yourself appear larger would be a better plan. You;d be constricted first anyway,
Finally, above all else, if this were really effective, I would think making sure you have your knife with you would be #1
