12. Puffer Fish
The Puffer Fish is cute, fat and innocent looking… but don’t let these looks deceive. The Puffer Fish is actually one of the most poisonous vertebrates in the entire world. It’s also a delicacy in Japan, for whatever reason.
Why would someone want to eat something so poisonous? Especially since if a Puffer Fish isn’t prepared properly the poison in the fish will cause your diaphragm to become paralyzed and stop your breathing.
