The whitespotted filefish (Cantherhines macrocerus) is a member of a family of fishes called Monacanthidae. They get their name from their extremely rough skin that resembles a file. The whitespotted filefish is found in the western central Atlantic Ocean along the coast of Florida extending southward into the Caribbean Sea. These fish have the ability to rapidly change their color to a high contrast color pattern which can blend in with their background. They grow to a maximum length of around 18 inches (46 centimeters).
