A snakehead fish found in Philadelphia in 2004.

UPDATE
Just to clarify so no one goes insane with anger, I photographed this snakehead at the Academy of Natural Sciences in Philadelphia. This is not owned by myself or any other private individual, so at least in the case of this guy, we are all safe from these "piscine carnivores" as BlueBerryPickn phrased it (quite beautifully, I might add)
