Since whales are teaming up with each other to take down yachts and teaching others how to do it I thought this would be a fun question.
If a majority of intelligent enough sea animals that could communicate with each other teamed up to mess with human activities in the sea who would win.
By the way for people that say that humans would obviously win we have already lost a war against emus before.
If we knew what was good for us, we’d be sinking those obscene money pits ourselves.
