Pufferfish, also known as blowfish, are located in tropical seas around the globe, especially around Japan, China, and the Philippines. Though they’re the second most poisonous vertebrate on the planet (after the golden arrow dart frog), they’re arguably more dangerous as their neurotoxin, called tetrodoxin, is found in the fish’s skin, muscle tissue, liver, kidneys, and gonads, all of which must be avoided—when preparing the creature for human consumption. Indeed, while wild encounters are certainly dangerous, the risk of death from a puffer fish increases when eating it in countries like Japan, where it is considered a delicacy known as fugu and can only be prepared by trained, licensed chefs—even then, accidental deaths from ingestion occur several times each year. The tetrodotoxin is up to 1,200 times more poisonous than that of cyanide, and can cause deadening of the tongue and lips, dizziness, vomiting, arrhythmia, difficulty breathing, muscle paralysis and, if left untreated, death.
