Looks like the ocean, probably cold water. He's swimming underwater. He wants to have big muscles. He's swimming around, he doesn't look like he's hunting. I don't think they'd be eating that type of fish with those stripes. You usually have to ride for quite a while on a ferry. You'd be the food if you came across a shark. Th sharks are scared of humans, I don't think they'd come across them. It seems if you stir them up, you'd get the sound of splashing and zig-zagging of the water.
