Info: Shark's Teeth

Sharks have similar-shaped razor sharp teeth in their mouths. A sharks may have as many as five sets of teeth, set in rows one behind the other. As the teeth in front, along the outside of the jaw, are lost or wear out, the teeth behind move forward and replace the lost ones. This process of teeth renewal continues throughout the sharks's life. As the shark grows bigger. in size, the new teeth tend to be bigger than the ones they replace. Not all shark's teeth look the same and a species can be identified by the shape of its teeth. The teeth of the great white shark are triangular with a serrated edge like a saw. The sand shark's teeth are more dagger-like.
