We travelled at lightening speed across the ocean in a silver and black speedboat. It was fitted with an on-board camera that displayed in real-time which creatures were being chopped to pieces as they got caught up in the propeller. When we returned to shore we saw a shoal of whale varieties in the bay. With them was a sea mammal new to me. I’d never heard of a “porcine” before, and there was nothing pig-like about it either, but there it was, playing with the killer whale.
