If you thought you were scared of sharks before - we've just upped the ante a little more. Some amazing GoPro video, taken by fishermen in Maryland, shows what it might be like to be eaten by a shark.
The waterproof camera was set up facing the back of their boat. The images reveal small baitfish swimming behind the boat. Within a few short minutes a huge mako shark comes out of the shadows.
This is one video you're going to want to watch and share!
