There I was, off the coast of North Carolina at a depth of about 20m (60ft) when the shadowy shape of the WWII wreck Caribsea came into view—but it looked almost as if it was moving! Upon closer inspection, it turned out to be a cloud of tiny bait fish completely covering the wreck. As they moved, the ship seemed to move with them; and then, out of the swarm, a massive, tank-like, gray silhouette emerged.
Sand tiger sharks (Carcharias taurus) look mean but in reality, they are quite docile. As I watched, at least 12 sharks crisscrossed the Caribsea wreck; they almost seemed to be in a perfect state of Zen.
