Description
The decoy scorpionfish is a small scorpionfish (Scorpaenidae) from the Indo-Pacific. The species grows to about 13 cm and has a stocky, red-mottled body. Its front dorsal fin bears a pattern eerily resembling a small fish; it waves it as a lure to draw prey within striking range. As an ambush hunter it shelters on coral and rocky reefs. The dorsal spines carry venom and can cause a painful sting; handle with care.
