No, unless there is a large group of jellyfish.
No; portuguese man o'war, or bluebottle jellyfish in not a jellyfish but a colony of many polyps.Each polyp is a single animal in the polypoid stadium (not medusoid), specialized in particular functions, and all together are joint to make a unique "body": the colony. The floating part is a polyp full of gas, called siphonophore; the "eating" part are polyps called gastrozoids; the stingy tentacles are the dactylozoids; while the reproductive sistem is provided by gonozoids.
A jellyfish sting from a box jellyfish can kill a person in minutes if not treated. From other jellyfish, it might only sting. you can atually help it if you urinate on it.
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.
It depends on how bad the sting is. If it is a mild sting they should recover, but if it is a major sting it can possibly kill you.
Yes it is true
Depending on the toxicity of the jellyfish that stings you, yes you can die from the poisons contained in the jellyfish's tentacles. However, that isn't very common.
jellyfish sting to protctet themselfe
It doesn't make a difference whether you're covered with whale urine or not, if you're near a jelly, you could get stung.
Forgive my spelling, but I think you're talking about the Iricongea.Probably the worst jellyfish sting comes from chironex flecterii aka the box jellyfish. Without prompt first aid, (and/or hospitalisation) it can kill. It is found mostly around Australia.
Jellyfish are neither friendly or aggressive. They have no way to tell a friend from a predator, so they do not sting you on purpose unless they are box jellyfish, which feel threatened by human populations.
They do.
