There is an anti-venom treatment for only one species of box jellyfish, Chironex fleckeri. Treatment for stings from all box jellyfish species starts with a complete flushing of the area by a mild acidic solution such as vinegar, or citric acid. This inhibits the unfired nematocysts from further envenoming the victim. All remaining tentacles should then be removed by picking, scraping, or flushing them off the skin with salt water. Do not press on the tentacles, nor rub them off with sand. Immediate medical assistance should be sought, since box jelly envenomation may be life threatening.
If not a box jelly sting, or if stung swimming in an area not typical for box jellies, do not use vinegar. Also, do not use urine, alcohol, meat tenderizer, acidic solutions, baking powder, or even fresh water. All of these have been demonstrated to trigger further envenomation in certain jellyfish species. Start treatment by flushing with sea water while removing all remaining pieces of tentacle. Once the area is free of tentacles, heat can help break down the venom proteins, so soak the affected area in hot water, or under a hot shower for 20 minutes. Fresh water is fine at this point if all remaining pieces of tentacle have been removed. The water should be as hot as possible (without scalding, of course). If heat is not available, an ice pack can reduce the pain, but it only offers temporary relief.
Again, please do not listen to old wives tales about urine, alcohol, and other home remedies; science has proven them to be less than worthless treatments. In short, flush box jelly stings with vinegar if available and call medics. Otherwise, flush with sea water and remove any remaining pieces of tentacle. Treat with heat, and ice is nice.
It depends on the species of jellyfish. The irukandji jellyfish has the potential to kill a person in 2 minutes.
No. A sea anemone and a jellyfish would not meet. If they did meet, the jellyfish would sting the sea anemone and kill it.
Yes a lion mane jellyfish can kill octopus. Because the octopus can not take the rage and power that the jellyfish is providing.
No.
great question, yes a portuguese man-of-war can kill a jellyfish.
No, unless there is a large group of jellyfish.
NO
For food.
kill
A large box jellyfish or a man of war jellyfish could if it had very long tentacles.
Most likely, yes. A man of war jellyfish has such deadly tenticles full of strong poison that could kill a shark easily.Another AnswerPossibly, but the man of war jellyfish is more likely to badly injure the shark than kill it. It all depends on the size of the tentacles of the man of war jellyfish and the type of the shark. But it is very likely for the man of war jellyfish to kill a hammer head shark or other smaller species of sharks.
