2. Shark Teeth: Pearly Whites Forever

Step aside, dentists of the world: sharks are the true masters of dental hygiene! Sporting perpetual pearly whites throughout their lives, these oceanic "tooth fairies" keep themselves constantly bristling with thousands of chompers, like a never-ending game of whack-a-tooth: Sharks have the astounding ability to regrow their teeth constantly, housing up to 3,000 teeth at once, spread across multiple rows, and replacing each fallen tooth within just a few days or months. This is due to a network of genes responsible for tooth development and regeneration, which humans also possess, paving the way for potential breakthroughs in human tooth loss treatments.

Step aside, rubber duckies: Sharks are the true floatation devices of the ocean!
