ScorpionfishesScorpaenidae

Scorpionfishes (family Scorpaenidae) are robust, stocky-bodied benthic fishes, typically with large heads and broad mouths. Their bodies are covered in an array of spines, ridges, and dermal flaps. These features, combined with mottled and cryptic patterns of browns, reds, or greens, provide highly effective camouflage against their surroundings. Most species possess venom glands at the base of sharp spines in their dorsal, anal, and pelvic fins, which deliver a painful defensive sting and explain their common name. Adult sizes for commonly encountered species range from about 10 to 40 cm (4 to 16 inches) in length.

These fishes are ambush predators, feeding on smaller fishes and crustaceans. They inhabit a wide range of benthic environments, including rocky reefs, coral gardens, rubble zones, and sandy patches, from shallow waters down to 100 metres (330 feet). Scorpionfishes remain motionless for extended periods, waiting for prey to approach before striking quickly. Primarily solitary and sedentary, they are frequently encountered by divers, though their excellent camouflage often renders them overlooked.
