Most likely, yes. A man of war jellyfish has such deadly tenticles full of strong poison that could kill a shark easily.
Another Answer
Possibly, 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.
It depends on the type of jellyfish and/or shark.
Probably. A large box jellyfish can kill a great white shark or any type of sharks.
it depend on which jellyfish . A box jellyfish can, a portuguese man of war is not a jellyfish but it might be able to.
No. The box jellyfish's toxic would not damage the whale.
It depends on the species of the sharks.
yes
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, unless there is a large group of jellyfish.
No. A sea anemone and a jellyfish would not meet. If they did meet, the jellyfish would sting the sea anemone and kill it.
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.
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.
A large box jellyfish or a man of war jellyfish could if it had very long tentacles.
jellyfish sting to protctet themselfe
They do.
They do sting.
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.
The shark would eat the fish, and then the electric eel and the jellyfish would hurt each, other unless it was a man 'o' war or box jellyfish, then it would just kill the eel, and then the shark could eat it too, and most jellyfish can't but the box and man o war if they stung it enough could kill a shark.
