Did you know that the animal that always grows new teeth to replace the old is the shark? Sharks are constantly shedding and replacing their teeth throughout their lives, with some species going through thousands of teeth in a single year!

This ability to regrow teeth is known as polyphyodonty, and it sets sharks apart from most other animals. While humans and many other mammals only have two sets of teeth (baby teeth and adult teeth), sharks have a never-ending supply.

Sharks have rows of teeth in their mouths, with new teeth constantly growing in the back and moving forward to replace the old ones at the front. This ensures that they always have sharp, efficient teeth for hunting and feeding.

This unique dental adaptation allows sharks to maintain their formidable hunting abilities throughout their lives. It also helps them recover quickly from any lost or damaged teeth, ensuring that they can continue to thrive in their marine environments.
