2. The Puffer Fish
Puffer fish are funny and cute just on general principle. It’s hard to see one inflated, and refrain from uncontrollable smiling at its cartoonish defense mechanism. But puffer fish don’t just rely on their inflatable belly as a way of warning predators, they are also full of deadly neurotoxin tetrodotoxin. Of course, they’re known as a delicacy just for this reason. Apparently, when prepared on the right way, the minute traces of the poison give you tingly lips and lightheadedness. But if the cook doesn’t prepare it in the right way, you risk a nasty death.
