More about pufferfish?
The pufferfish is the second most poisonous vertebrate on the planet. Its poison has no antidote and kills by paralyzing the diaphragm, causing suffocation.
Almost all puffer fish contain tetrodotoxin, a substance that makes them taste bad (and sometimes lethal) to fish.
According to National Geographic, tetrodotoxin is deadly, up to 1,200 times more poisonous than cyanide. One puffer fish has enough toxin to kill 30 adults.
Tetrodotoxin does not cross the blood-brain barrier, so the victims remain fully conscious while their central nervous system gradually shuts down. Symptoms such as numbness in the mouth, lips, and tongue occur within 30 minutes to three hours from an intake and after that, the victim begins to experience headaches, nausea and even vomiting. The rest of the body slowly becomes paralysed, causing death when the heart and lung muscles are also paralysed.
