Sharks have a conveyor belt of teeth
Sharks continuously replace their multiple rows of teeth, operating like a conveyor belt to ensure they always have a razor-sharp bite for hunting prey.
Sharks possess an incredible dental system: multiple rows of teeth that regenerate like a conveyor belt. When a front tooth is lost or worn, the entire row shifts forward, and a new tooth emerges from the back. This ensures sharks always have sharp teeth for grasping prey, as they don't chew their food. Some species, like the great white, can have hundreds of teeth at once and replace them every few weeks, cycling through tens of thousands in a lifetime. This constant renewal is vital for their role as apex predators. Interestingly, shark teeth are modified scales, not true teeth like ours.
