In this episode, we’re asking sharks to say “aaaah”, and taking a close look at their chompers. We’ll see how shark teeth grow, and what those teeth can teach us about sharks of the past. We’ll also play a game of Jaws Jeopardy, and find out how sharks help keep the ocean helping with their super snacking. Stick around for a listener-submitted mystery sound and a Moment of Um: why does steam rise in the air?
