I do like to swim in the sea and, I've always liked to go out quite far, where the water is calmer but, if I start to think of stuff like that that could be mooching about bellow me, it properly freaks me out.
I read about Greenland sharks years ago - that lifespan is amazing and, I think they're a creature that deserves respect.
............ I still wouldn't want to be front row for that image though.
