While all venomous snake bites are a serious worry, most take longer than you’d expect to kill a fully grown human. That's because venom typically works by slowing down the body’s vital systems until the victim drifts off to death.
But the blue coral snake (Calliophis bivirgata) is different. These beautifully coloured snakes from South East Asia and have a venom that's so powerful, it can trigger all of the victim's nerves to fire at once, instantly trigging full body spasms, paralysis, and a quick, horrifying death.
