I believe that some friends who like to go to the beach to play should have found jellyfish on the beach, jellyfish is a very good-looking, swimming posture is very beautiful plankton, in some marine life halls have their figures, but as the saying goes, the more beautiful things are more dangerous, this beautiful jellyfish although good-looking, but it is poisonous, jellyfish will shoot venom through their own hands on the venom to hunt, today Xiaobian to say is the most poisonous jellyfish in the world, if people touch their tentacles, they will die after 30 seconds.
This kind of toxic jellyfish is called box jellyfish, the most representative of which is the Australian box jellyfish, also known as the sea wasp, do not look at its appearance so flexible and ethereal, it is the world's first poison, a little poison can put people to death, a box jellyfish toxin is enough to poison 60 adults, if it is poisoned, 4 minutes without treatment, then it must die.
The tank jellyfish has 60 tentacles, full of thorns, each antennae is up to 9 meters long, its stinging sacs are lined up on it, the box jellyfish moves extremely quickly, it is very difficult to find in the water, so if humans in the sea once stuck by its tentacles, it is usually bound to die, it will first give you deadly poisonous juice, will first let you experience the pain of knife cutting, and then die of respiratory failure.
Although this "deadly poison" is very scary, but it still has natural enemies, mainly turtles living in tropical seas, this turtle is called the leatherback turtle, their favorite food is the box jellyfish, the leatherback turtle is the world's largest turtle turtle, known as the "giant turtle". The head, limbs and body of the leatherback turtle are covered with smooth leathery skin and do not have shields. These turtles are not afraid of stingers on jellyfish tentacles, so these jellyfish have become the main food source for leatherback turtles.
