"I have always envied dolphins; swimming around in the ocean and not having to wear clothes or have boring jobs or go to war with their own kind"
I certainly understood your main point, but sadly enough, the fact is..Dolphins (porpoises) have been documented with video killing other clans, and other subspecies of porpoise. I have seen it first-hand on TV documetaries, and it was very tough to watch them while they were basically "murdering" the other one's they chose to attack and kill. They bashed them with blunt-force trauma with their snouts, and also showed very clearly them being held down so they couldn't surface to breathe...drowning them.
It was pretty nasty stuff to watch, but nature can be extremely cruel. It's just the way it is.
