the Great White. Each tooth has super fine serrations on each side of the tooth.

Now let's take a look at the individual tooth of the Great White. Each tooth has super fine serrations on each side of the tooth. Being the amazing creature this shark is, the upper and lower jaws always seem to know where their opposite replacements are going to come in. This way, they don't have a problem meshing with each other as they shark bites down. Each tooth "interlocks" with it's corresponding tooth on the other side of the jaw. And the clearances between the teeth are such that whenever the shark chomps down there is very little room for anything but teeth. Whatever is in between is literally sheared away.  In fact you could say the teeth work very much like a pair of scissors. Except for the fact that they are traveling in opposite directions when they meet. And when you factor in the fact that once the shark bites down it begins to shake violently back and forth, one can see how devastating and powerful such a chomp can be.
