And this is exactly why I don't want anything to do with getting in a cage to observe sharks in the water. This is also why I don't desire to swim with sharks either. Check out this enormous shark going nuts on a cage that has divers in it.

The YouTube description for the video says that the the shark is an 11.5 foot great white and this happened in South Africa. Yikes! I'm all set with that type of underwater adventure.
