Pufferfish Also known as blowfish, pufferfish are found in tropical seas worldwide and are classed as the second most poisonous vertebrate after the golden poison dart frog. When threatened by a predator, they inflate by rapidly ingesting huge amounts of water or air – believed to have developed to compensate for their slow swimming speed. If caught, most pufferfish will release enough terodotoxin – a deadly venom up to 1,2000 times more poisonous than cyanide – to kill 30 people, with no known antidote. However, most human deaths occur when it’s eaten, as the flesh is toxic if not properly prepared.
