The ocean is just one big bathroom anyway. It's all a matter of perspective. If a whale took a dump in your bed, you'd be like "Fuck that, I'm sleeping on the couch!". But a whale takes a dump in the ocean and you're like "Surfs up dude!". I, mean, not you, literally. I don't know you. The collective "you".
This is nothing new, lots of ocean creatures use this method. I have a Crocea clam that over 7 years has blew it's load 3 times now, it makes a mess of your tank.
