Recorded distribution in Britain and Ireland
In the British Isles, Solidobalanus fallax has only been recorded from the southwest coasts of England and Wales.
Considered native to the Atlantic Coast of tropical Africa, Solidobalanus fallax is considered to have extended its range North through Portugal and France to Belgium and the Netherlands.
Solidobalanus fallax is typically epibiotic on a wide range of organisms including other crustaceans, hydroids, algae and molluscs. It has also been recorded from man-made objects such as plastics and lobster pots. Solidobalanus fallax is found in the upper sublittoral to around 200 m.
- Shell almost globose, with thin walls.
- Basis and shell plates without pores.
- Lateral projections on shell plates sloped, giving the orifice a toothed look.
- Opercular membrane yellow with brown or black banding.
Additional informationSolidobalanus fallax is considered to be non-native within the British Isles as well as northern Europe believed to have relatively recently expanded its range northward from Africa.
