There's tons more. Thing is, many whales often beach themselves. It's sad but it happens. Orcas actually bum rush beaches for pray, there's some cool video of them picking up some McSeaLions out there. So, SeaWorld has included portions of show where they beach themselves. They associate that with feeding. That whale may have simply been wanting more food. You know, Pavlov and all that.
That was wreckless, sensational drivel posted here. But... the world is full of Rubes lapping that propaganda up.
