 Box Jellyfish

The Indo-Pacific or Australian box jellyfish is the most poisonous marine animal known to mankind, and its sting can kill a human. It can be found in Australia’s northern oceans and throughout the tropical Indo-Pacific. It has up to 60 tentacles, each growing as long as 15 feet. The tentacles are covered in cnidocysts, and each cnidocyst is equipped with a tiny needle and a load of toxin that, added together, could kill 50 people. Their venom is considered to be among the most deadly in the world, containing toxins that attack the heart, nervous system, and skin cells. It is so overpoweringly painful, human victims have been known to go into shock and drown or die of heart failure before even reaching shore. Survivors can experience considerable pain for weeks and often have significant scarring where the tentacles made contact.
