Black scorpionfish (Scorpaena porcus)

Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

Scorpaena porcus can grow to a length of 37 cm but is more commonly between 15 -20 cm. It is browny or orangy in colour with lighter patches and numerous skin appendages, which make for good camouflage. The caudal fin has three dark, vertical bars, and there is a light spot between the eigth and ninth dorsal spine. Behind the gill cover (operculum) there are usually two spines.

Recorded distribution in Britain and Ireland

The south coast of England represents the northern limit of Scorpaena porcus. It is an infrequent visitor to the coastal waters off the south coast and is unlikely to be seen very often.

Habitat

Scorpaena porcus is a benthic species found from the littoral zone down to a depth of around 800 m. Usually seen motionless and solitary amongst rocks and algae on the seabed.

Identifying features

  • Brown or orangy brown in colour and growing up to 37 cm in length.
  • Three dark vertical bars on the caudal fin.
  • Numerous well developed skin appendages and spines.
  • Large fleshy appendage behind eye.
  • Light spot on skin between the eigth and ninth dorsal spine.

Additional information

Scorpaena porcus is similar to Scorpaena scrofa in morphology and distribution. However, Scorpaena scrofa occurs in water between 20 -110 m, is a brighter orange colour and has less well developed spines behind the operculum. Scorpaena scrofa also grows to a length of 51 cm.

Spines of the dorsal, pelvic and anal fins of black scorpionfish have venom glands at their bases. The venomous spines cause an intense pain and throbbing to people stung by it. Treatment is to immerse the affected area in water heated to tolerance level and to disinfect the afflicted area.

This species is also known as the small-scaled scorpionfish (D. Herdson, pers. comm.)
