There are species of animals out there that often give us mixed vibes, and it's not usually easy to spot the ones that are actually dangerous. A cuddly, sweet and seemingly benign animal can sometimes be deadly, even if it doesn't show its true colors too often.
1. Box Jellyfish
There aren't many movies showing the deadly power of box jellyfish – unless you count Finding Nemo – but with up to 60 tentacles, 5,000 stinging cells on each tentacle, and enough toxins to kill dozens of people, this mysterious and deadly sea creature is responsible for up to 100 deaths per year.
