Watch out for the world’s deadliest jelly fish
Daily Mail | April 3, 2017
The box jellyfish is one of the deadliest creatures on earth.
The tentacles of fully grown box jellyfish can reach nearly 10 feet in length and contain about 5,000 stinging cells per tentacle.
They use their venom to stun or kill fish or other prey, but even a small amount can be lethal for humans.
The venom of the box jellyfish, found in tropical and subtropical oceans, disrupts the heart and nervous systems and can cause heart failure within minutes.
Medical professionals say all cases should be treated as urgent and potentially lethal.
EDITOR’S NOTE: Here in the Gulf waters, the worst stings are caused by the tentacles of the Portuguese Man O’ War, which is not a true jelly fish although lay persons consider it to be.
