This scene is also inspired from Air Jaws, the TV show that is shown during shark week, one of my favorite weeks of the year. If you haven't seen it or heard about it, read up on it and watch it! No matter how many times you see it, you'll be amazed. What you see here is the Great White going after a Brown Fur Seal, which they attack from below and come out of the water due to their high rate of speed. They have been known to fully leap out of the water because of this as well.
