|Researched by||Kate Reeds||Refereed by||Admin|
|Other common names||-||Synonyms||Balistes carolinensis Gmelin, 1789|
Recorded distribution in Britain and IrelandAdult specimens have been recorded in increasing numbers around the western coasts of Britain and Ireland. There is no current evidence of a breeding population in Britain and Ireland.
HabitatMainly rocky bottoms and floating wreckage at depths between 10-100 m.
- Brownish green to grey in colour.
- Up to 40 cm in length.
- Small, beak-like mouth with fleshy lips.
- Latitudinally flattened body.
- First dorsal fin may be locked upright or flat.
- Not currently in British waters.
Additional informationCommon in the Mediterranean, where spawning occurs in water temperatures above 12°C. As they are poor swimmers, it is likely they arrive in the Eastern Atlantic to the North coast of Angola via the Gulf Stream. They may increase in numbers in Britain and Ireland because of warmer seas due to global warming.
