Scorpaena scrofa, the red scorpionfish, bigscale scorpionfish, large-scaled scorpion fish, or rascasse is a venomous marine species of ray-finned fish in the family Scorpaenidae, the scorpionfishes. It is found in the Mediterranean Sea, in the eastern Atlantic Ocean and the western Indian Ocean.
Scorpaena scrofa is the largest eastern Atlantic scorpion fish. Its colouration ranges from brick red to a light pink, and it has dark-coloured blotches on its body. It has venomous spines, and can achieve a maximum weight around 3 kg (6.6 lb). It can grow to a maximum length of 50 cm (20 in), but is commonly around 30 cm (12 in).
It has 12 dorsal spines, 9 dorsal soft rays, three anal spines, and five soft rays. It often has a dark spot on its spinous dorsal spines between the 6th and 11th. It has long supraorbital tentacles.
Scorpaena scrofa is found in the Mediterranean Sea. It is also found in the eastern Atlantic Ocean around the British Isles, where it is rare, south to Senegal, the Canary Islands, and Cape Verde.It is also found in the Azores Island of São Miguel; It is also found from Namibia south and east along the coast of South Africa into the western Indian Ocean, its otherwise circum-African distribution is interrupted between Guinea and Namibia where it is apparently replaced by the spotted-fin scorpionfish (S. stephanica). In the Indian Ocean the northern most record is from the Gulf of Aqaba and, given its occurrence elsewhere in the western Indian Ocean, it is thought that this record is unlikely to be the result of anti-Lessepsian migration from the Mediterranean through the Suez Canal.
Scorpaena scrofa is demersal and lives in marine and brackish environments with rocky, sandy, or muddy bottoms at depths of 20–500 m (66–1,640 ft). By day, it lives in burrows and caves. At night it comes out to hunt.
Scorpaena scrofa is a sedentary, solitary, and nonmigratory fish. It is predatory, feeding on other fish, as well as crustaceans and molluscs. This is one of the fish used by the marine leech Pontobdella muricata as a host.
