A rare video has emerged from Mexico of a whale shark biting a fishing boat. <br /> <br />In the clip, which was captured in the Sea of Cortez on May 15, the enormous fish swims slowly up to the boat and clamps its mouth around the swim deck. <br /> <br />Fortunately, whale sharks are filter feeders and only have tiny teeth so the boat was not damaged. <br /> <br />Whale sharks are the world's largest fish.
