Why do the teeth of great white shark help them?

Great white sharks have rows of sharp, triangular teeth that are designed for catching and tearing prey. Each tooth has a serrated edge that helps the shark to grip and hold onto its prey. The teeth are also replaceable, so if one is lost, it will quickly be replaced by a new tooth.

Great white sharks use their teeth to hunt for a variety of prey, including fish, seals, sea lions, and even other sharks. When they attack, they typically use their powerful jaws to bite their prey and then shake their head from side to side, tearing the flesh.

The teeth of great white sharks are also used for defense. If a shark is threatened, it will often open its mouth and display its teeth in a warning gesture. This is usually enough to deter potential predators.

In addition to their hunting and defense functions, the teeth of great white sharks also play a role in social interactions. When sharks meet each other, they will often bite each other as a way of establishing dominance. These "ritualized bites" are usually not harmful, but they can serve to determine which shark is the strongest and most likely to win in a fight.
