Yeah its a shame I couldn't find any live pictures of a stoplight loosejaw. I kinda think there aren't any. The lower jaw is cool, less water resistance for faster snapping.

My brother had a pretty bad run in with some black damsel fish. They left these huge welts on his ankles, which I found rather funny.

The most badass salty has to be the Great Barracuda.
