Basic purpose of this lecture is to present on Great White Shark Information. Great whites are the only sharks that can hold their heads up out of the water. This ability allows them to look for potential prey at the surface. Great white sharks usually attack from underneath, surprising their unwary prey. If great white sharks had tooth fairies, they’d be rich! A great white loses and replaces thousands of its teeth during its lifetime. Its upper jaw is lined with 26 front-row teeth; its lower jaw has 24. Behind these razor-sharp points are many rows of replacement teeth.
