Mad …or Just Showing Teeth

I’m not using macro. And I’m not challenging. He’s not challenging either. The coral hind is a big chicken. Well, he’s a fish that would prefer to flee rather than confront. I trap them periodically under coral. Nowhere to retreat. Or he feels like I can’t pursue. Or, he thinks I can’t see him. Who knows? Anyway, I can occasionally get a good head on shot. Ok, done, been there, done it. Now I got teeth. I know sharks have teeth. So too does this brand of fish. They are not large. Do they fall out and are they replaced by new sharp teeth that will rip your guts out? Ah! And why don’t fish have eyebrows?
