While sharks might freak you out, they’re not nearly as dangerous as another creature lurking in the ocean-the box jellyfish. This creature’s venomous sting packs quite a wallop. To put it in perspective, you have a better chance of surviving the bite of a black widow spider than a box jellyfish. What’s worse is that box jellyfish stings are not that uncommon. More people die every year from their sting than shark attacks.
