The most venomous animal on Earth is the Australian box jellyfish. Commonly known as the sea wasp or the transparent killer of the ocean, it is a jellyfish that lives in Australia, northern New Guinea, the Philippines, and Vietnam. They have caused countless injuries and deaths to humans worldwide and are considered the deadliest jellyfish.
This jellyfish is only about 16 inches long and has 24 eyes in four clusters. Its tentacles are covered with thousands of stinging cells that store venom; not only malicious attacks, but even accidental brushes against its shell or skin can stimulate these tiny stingers. If anyone dares to provoke it, it will frantically inject any person or object with the most potent known neurotoxin, capable of killing a person within 30 seconds.
The Australian box jellyfish has 60 tentacles, each 3 meters long, covered with over 5,000 stinging cells and enough venom to kill approximately 60 people. When it attacks humans, it flings its tentacles a considerable distance, first entangling swimmers or divers, then using its venom to block their breathing. It is said that only those stung by sea wasps within minutes of receiving an antidote can survive!
The Australian box jellyfish is recognized as one of the world's ten most venomous animals, its venom more dangerous than that of a cobra. An adult box jellyfish is the size of a football, mushroom-shaped, and nearly transparent. A single adult box jellyfish has billions of venom sacs and stingers on its tentacles—enough to kill 20 people, demonstrating the extreme venom's potency. Its venom primarily damages the heart; when it enters a person's heart, it disrupts the rhythm of the body's cells, preventing the heart from pumping blood properly and leading to rapid death.
