All jellyfishes sting; however the "burning" effect is due to the inoculation ofallergens: jellyfishes who don't inoculates allergens don't cause a "burning" (anaphylactic) reaction, like rhizostomeae jellyfish; however they could inoculate some other substances like hemotoxic poisons. Clear jellyfish do not sting, if they do then the effects aren't large enough for a human to feel, coloured jellyfish do sting and it will be painful

It is true that most clear (and colored, for that matter) jellyfish either don't have a venom strong enough to be dangerous to humans, or their stingers can not penetrate human skin. However, it is totally incorrect to say that all clear jellyfish are harmless. The most venomous and deadly of all jellyfish are very clear and virtually impossible for humans to spot while wading or swimming along the shore.
Although Chironex fleckeri have bells the size of a Basketball and trailing tentacles up to 30 feet long, they are so transparent that seldom does a victim ever see the culprit that stung them. Their sting is so painful that many claim that amputation of the envenomated limb would be preferable to enduring the excruciating pain. Probably less than 50 humans a year die from these jellies, but thousands of victims would almost prefer that outcome.
Another deadly, but much less lethal jellyfish is the species, Carukia barnesi. It is both clear and smaller than a thumbnail. It was so elusive to scientists that it wasn't until 1964 that Dr. Jack Barnes finally captured and identified the species that was causing 'Irukandji syndrome' and responsible for several deaths. To confirm that this jellyfish caused Irukandji symptoms, Dr. Jack Barnes stung himself, his son, and a lifeguard. All three had to be hospitalized with life threatening symptoms.
The initial sting from an Irukandji jellyfish is only mildly painful, and sometimes even goes unnoticed. But a half-hour later, extreme muscle cramps, shooting pains over the body especially in the chest and stomach, vomiting, and convulsions then ensues. The violently painful symptoms, even under a full dose of morphine, causes some of the victims to claim that they would rip their skin off if possible.
The answer to your original question, however, is that all jellyfish sting. They are in the phylum, Cnidaria, which means 'nettle-like', and they all have microscopic stingers variously called cnidocytes, cnidoblasts, or nematocytes. The vast majority of jellyfish, however, are innocuous to humans. Only about 100 species out of many thousands of Cnidarians are considered venomous to humans.
Yes there are, mostly the ones in the Pacific.
not if you attack them they are more scared of you then we are to them.
Because jellies are invertebrate, none of them are considered fish.
they have a skin that when they sting themselves they can't feel it
Infact, all jellyfish sting. Except for The real thing is that the jellyfish that don't 'sting', really do, it's just not strong enough to penetrate the human skin.
yes some people eat jellyfish they also sting us!
There are numerous effects of a jellyfish sting, such as jellyfish dermatitis, which is a cutaneous condition or, of course, short-term memory loss. (I can't think of any other one right now)
yes. sting ray,manta ray,jellyfish and more.
Generally speaking, the jellyfish's first line of defense are its stinging cells. In particular, when attacked or otherwise distressed, some species of jellyfish will detach their tentacles, and, if the jellyfish are deep-sea or nocturnal, glow very brightly, thereby stunning its attacker.
I dont think that they have any predators.
They are quite different in their apearance but one common thing is they sting their predator or any thing that disturbs them.
No. Jelly fish dont have any bone, so they are a invertebrate.
I was stung by 3 jelly fish, first I applied vinigar but dident feel any releif from the pain, then I had a VERY HOT shower with gave immediate relief then i put mono floral honey (pure 100% honey) on 2 of the 3 stings. The 2 stings that I applied honey too were 80% gone with in an hour or applying the honey. The one sting I did NOT rub with NO honey was still sore and still had big red welts 72 hours later. 100% Honey works very good on jelly fish stings.
Keep out of the ocean, or be extremely careful. The sting is painful, and some species can be deadly. ^^^This wasn't helpful...i would like to still be able to go in the ocean without being stung if possible...any suggestions?
I dont know mabye,mabye not go jump in a lake and find out yourself!
