  I think the The Portuguese man o’ war (jelly fish) is quite dangerous (although perhaps not the most dangerous to humans):

  The black marlin is the fastest fish that we know of it can go up to 129 km/hr. The most dangerous animal to humans in the ocean.. there are lot to choose from.. but I am a big fan of the pufferfish as it produces the most deadly poison known to us! Tetrodoxin or TTX.
