QUESTION: What is the world’s most venomous sea creature?
ANSWER: Box jellyfish are the world’s most poisonous marine animals, with up to 15 tentacles containing 5,000 stinging cells that release a toxin causing rapid blood pressure spikes and heart failure. The sting is so unbearably painful that human victims have been known to go into shock and drown—or die from heart failure—before even reaching the shore. While there are an average of six fatalities from shark attacks per year, box jellyfish stings result in between 40 and 100 human fatalities annually.
