I got one that beats all the animals on here!

The Ferdelance! Its a snake. When I lived in Panama the locals called them "2 Steppers" meaning one bite you get 2 steps and your dead. Which is kind of true. One bite and without IMMEDIATE medical attention your a gonner. My older brother saved my life from one. I was 6 years old and he was 11. We were walking down a trail through the jungle and he suddenly told me to stop. Right in front of me was a Ferdelance. If I had moved it would of bit me. But my brother cut its head off with his machete. The life of a military kid
