the shark would win unless its a large jelly species.
The shark.
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.

a tiger would win
the great white shark will win
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.
A shark
it mainly depends on the circumstances. If the dolphin is alone, and trys to fight the shark, it will be killed. But if it was a pod of dolphins, the dolphins would have the upper hand. But as for your question, if the shark got into a fight with a GREAT WHITE, the shark would eventually either bite the dolphin, or the dolphin would run away.

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.
tiger shark
Mostly the Tiger shark would win. Most species of hammer heads are smaller than the tiger shark and hence would lose.
