Pretty interesting find. (Not completely sure if this is the right community for this- let me know if you know where else it would be a good fit!)

They aren't the only ones. Beavers do too! So does the Giant Pacific chiton (world's largest chiton, a type of mollusk).

Pretty useful for animals that have to scrape food off rocks or continually gnaw through something.

I guess Komodo dragons need those teeth to last, whereas sharks are just like "I got a million of these things."

And bloodworms have copper teeth! I guess they get it from the sediments they live in. That blew my mind, so finding this out about reptiles is so wild.
