I guess Sparky doesn't like escargot!

Backwards facing ridges? Those are his teeth (or well the fish equivalent; they are made of dentine). They help him grab onto his prey (fish in the wild). Fish with sharp, backwards facing teeth are fish-eaters (piscivores). Fish teeth aren't always attached to the jaw. Most of the time, they are in those ridges on the top and bottom of the mouth.
