This is an incredible video! A great white shark was biting at a large chunk of tuna when it lunged forward and busted into a shark diving cage. Luckily the man inside the cage is an experienced dive instructor and escaped unharmed!
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.
