Cascabel
This South American serpent, a member of the larger rattlesnake family, chose to live in Argentina’s region by shaking its maracas (shakers, if you will). If you ever hear it shaking its shakers, you should run away as fast as you can. The Cascabel lives between 10 and 25 years on average, but its bite can kill a person in that time!

Darevsky’s Viper
The zig-zag shape of this creepy creature isn’t the only thing that makes you dizzy. Their foldable fangs pack a punch (or possibly a bite) that injects venom into their prey. Their venom is stored in glands behind their eyes! It’s not surprising that their vision isn’t great.
