The most poisonous jellyfish is the Australian jellyfish. The poison of a box of jellyfish is enough to poison 60 adults. If the poison of the tank jellyfish is in the middle, if it is not treated within 0 seconds to 4 minutes, it will die. The Australian box jellyfish is a light blue transparent jellyfish shaped like a box with 4 distinct sides, each 20 cm long.
The box jellyfish has 60 3 meter long tentacles, each of which is covered with stinging cells that store venom. The only way to avoid being attacked by the sea hornet is to avoid swimming in the waters where the jellyfish are infested.
At present, warning signs are displayed on all beaches in northeastern Australia to alert people to this jellyfish. Scientists are working hard to find more effective antidote and ways to prevent their attacks.
