The clownish grin of a bridled parrotfish reveals its power tools: grinding teeth used to scrape algae from rock. Though sometimes destructive to individual corals, the fish's efforts are mostly beneficial. Without them, algal growth could smother the reef. Scarus frenatus

You can hear them crunching on the reef when you are snorkeling . It's a freaky sound.

Cool pic. I always wanted to know what their teeth looked like.

So that's how clown make-up originated :cool:
