This common scorpionfish is often overlooked because of its very cryptic appearance, looking very much like an algae-covered rock. When disturbed, it will sometimes pull forward its large pectoral fins as it darts off, revealing bright orange color underneath, which is thought to be intended to startle would-be predators. Its rock-like appearance often causes it to locally be mistaken for the highly venomous stonefish, Synanceia verrucosa, but that is another species treated elsewhere. Scorpaenopsis diabolus is quite venomous in its own right, making appropriate the common name Devil scorpionfish.
Thes may be young Scorpaenopsis diabolus, or may be a related smaller species.
