                                According to scientific sources, the neurotoxin found in puffer fish is up to 1,200 times more potent than cyanide. This dangerous substance, which is not destroyed by cooking, is known as tetrodotoxin (TTX) and can cause rapid, life-threatening paralysis in humans if ingested.
