This absolutely massive shark
gives the people on this boat a right old scare. With the audio appropriately set to the "Jaws" theme, this huge predator gives the boat a nice little swim by, surely raising the heart beat of the people on the boat more than a little bit, as evidenced by the video's text.
Perhaps the most fascinating feature of the video however comes in the form of the large wake in the water created by the shark, something not often seen to this scale. But then again, there aren't too many fish this big out there either. The wake looks more like it's being created by an invisible boat than something under the water, but once we see the shark's size, it all makes sense.
Fortunately, it would appear that this beast is actually a Basking Shark, which only feast on Plankton. But are you willing to test that theory out?
