We are halfway through Shark Week! Have you learned how many teeth Sharks have yet?

Sharks have around 50 teeth with multiple rows (approx. 300 teeth) in development at one time.  Over the course of their lives, they can have up to 50,000 teeth! When one tooth pops out, another one falls into place.  It's a good thing humans aren't the same way, or we wouldn't need dentists!
