Polyphyodont

Polyphyodont is a fancy word that means having many sets of teeth in your lifetime. You know how you have baby teeth, and then they fall out, and you get bigger teeth? Well, some animals have that happen many times throughout their lives.

For example, sharks are polyphyodont because they constantly lose and replace their teeth. They have rows of teeth behind their front teeth that are ready to move forward and push out any teeth that get worn out or damaged. This way, they always have sharp teeth to catch their prey.

Polyphyodont is a special adaptation in nature that helps animals stay healthy and survive in their environment. It’s like having a backup plan for teeth!
