The 9 Most Dangerous Animals in the World

#4. Pufferfish

Pufferfish, also known as blowfish, are located in tropical seas around the globe, especially around Japan,
China, and the Philippines. They’re more dangerous as their neurotoxin, called tetrodoxin, is found in
the fish’s skin, muscle tissue, liver, kidneys, and gonads. 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. Itcan only be prepared by trained, licensed chefs, whose accidental deaths from ingestion occur several times each year. Pufferfish contain tetrodotoxin, a substance that makes them foul tasting and often lethal to fish. To humans, tetrodotoxin is deadly, up to 1,200 times more poisonous than cyanide. There is enough toxin in one pufferfish to kill 30 adult humans, and there is no known antidote.
