Devil Scorpionfish close frontal and profile

Devil Scorpionfish, aka False Stonefish, are masters of camouflage, enabling them to lie in wait on the sea floor for unsuspecting prey. They rely on their color, which they change to blend in with their environment. Some grow filaments resembling algae or get covered in hydroids to blend in even better.
 
Scientific Name:  Scorpaenopsis diabolus
