Devil Scorpionfish Identification Guide

Key identification features

• Heavy-bodied, mottled gray, brown, and reddish coloring that closely matches surrounding rock or rubble
• Rough, bumpy skin texture with fleshy tabs and flaps over the head and body
• Large, upward-tilted mouth and eyes set high on a broad head
• Bright orange, yellow, or black-spotted underside of the pectoral fins, flashed briefly when disturbed
• Venomous spines along the dorsal fin; grows to about 25-30 cm (10-12 in)

Common look-alikes

• Stonefish: even more heavily warted and lacks the bright flash coloring under the pectoral fins that devil scorpionfish display when startled
• Leaf scorpionfish: thinner, more compressed body shape with a distinct leaf-like silhouette, unlike the devil scorpionfish's stockier build
• Other reef scorpionfish: generally have smaller fleshy head flaps and less contrast between camouflage color and the hidden pectoral fin color

Where you'll see one

Devil scorpionfish sit motionless on coral rubble, sand patches, and reef bases throughout the Indo-Pacific, from the Red Sea to Hawaii, relying on stillness and camouflage rather than flight to avoid predators.
