@Qbitzerre @lednaBM I had a marine mammals class in college in which the professor challenged us to come up with an answer to why whales beach themselves. I said off-handedly that it was a ritual suicide following their religions' directions. The rest of the class didn't find it as entertaining a thought as I did. (Whales will re-beach themselves further down the coast if you "save" them btw.)
@Cubelet @lednaBM did anyone have a better explanation?
