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.
No, unless there is a large group of jellyfish.
Yes it is true
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.
The whale would win because it can just eat the box jellyfish. The box jellyfish's toxic is too small to damage the whale a little bit.
Yes.
Humans and Jellyfish
Extremely doubtful. There's no scientific reason I'm aware of that this should work. However, folklore has carried this tale forever. If there is any basis, it might be that urine is both acidic and saltier than fresh water, and thus is less likely to activate unfired nematocysts (the stinging cells) than fresh water would be.
Sting ray's Skates and ratfishes
about 75% of all perfume in the US contain whale urine and 50% contain monkey blood.
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.
Water
most squids and some octopus have the enemies of a blue whale or killer whale killer whale would also eat a jellyfish if their hungry enough, sometimes they would even squeeze the jelly from a jellyfish. Sometimes the killer whale would win, other times the jellyfish would win the battle. Go jellyfish!
