Recorded distribution in Britain and IrelandThis species is rarely seen but has been recorded from the southwest of England, the west coast of Scotland and Wales, as well as the northeast coast of Ireland.
Global distributionRecorded from the west coasts of the British Isles and the northwest coasts of France.
HabitatThis species can be found buried in sand, gravel or mud, and also attached to rocks and shells. Has been recorded from the lower shore to offshore depths of 600 m.
Depth rangeLower shore - 600 m
- Wide bell-shaped column with a base of 7-9 cm in diameter.
- Up to 150 tentacles arranged in concentric cycles.
- Tentacles short with a terminal knob on each.
Additional informationThis species' short tentacles distinguishes it from any other British anemone. In addition, they contain relatively few Stinging cells (nematocysts). Food particles are taken in when the throat everts, with no assistance from the tentacles. It is able to rapidly retract its disc and tentacles. Its broad base may be an adaptation to living in soft substrata as it acts as an anchor (Manuel, 1988).
