Box jellyfish can weigh up to 4.4 pounds (2 kg)
Although the notoriously dangerous species of jellyfish are largely or entirely in the tropical Indo-Pacific, various species of jellyfish are often found in tropical and subtropical oceans, including the Atlantic and eastern Pacific, with species as far north in California, Mediterranean Sea (for example, B. Carybdea marsupialis) and southern Japan (for example, Chironex yamaguchii), and as regards South Africa (for example Carybdea Branchi) and New Zealand (for example Carybdea sivickisi) The box jellyfish was confirmed as "most venomous creature in the world, even if only a few species of the class is that being involved in the death of man and some species do not constitute a serious threat., for example, the sting of the results Chiropsella revealed only short-term , itching and pain.
Each tentacle has about 500,000 cnidocytes that contain nematocysts, harpoon-shaped microscopic mechanism injects venom into the victim. In Australia, the fatal poisoning are often committed by the largest species of this type of jellyfish Chironex fleckeri, carried out for the high effectiveness of the poison in their nematocysts. At least two deaths in Australia have Miniature Irukandji jellyfish attributed to size. Recent deaths in Australia have been in children who have linked their lower body mass. The box jellyfish actively hunt its prey (zooplankton and small fish), instead of driving to make a real jellyfish.
Poison Cubozoans Scyphozoa is different and is used to capture prey (small fish and invertebrates, including shrimp and bait fish) and for defense against predators, including butterfish, batfish, chimera, crabs (blue swimming crab) and several species sea turtles (hawksbill turtle, flatback turtle). Sea turtles, but apparently unaffected by the sting and eat box jellyfish.

Vinegar household confirmed as an effective treatment, as nematocysts sea wasp out is not released into the bloodstream. Tentacles sting even when separated from the bell, or the creature is dead.
For a higher degree of intoxication Although commonly recommended in folklore and even some papers on sting treatment, there is no scientific evidence that urine, ammonia, water, meat tenderizer, sodium bicarbonate, boric acid, lemon juice, freshwater, steroid cream, alcohol , cold packs, papaya, or hydrogen deactivates the stinging, and these substances can also accelerate the release of poison. Immobilization bandages pressure, alcohol or vodka should never be used for jelly stings Chironex fleckeri points are severe heart failure can occur quickly, so resuscitation (CPR) can save your life, and takes precedence over all other treatment options in 2011, announced the University of Hawaii research assistant professor Angel Yanagihara was an antidote to "deconstruction" of the poison from box jellyfish tentacle developed.
