|Researched by||Dr Keith Hiscock||Refereed by||Admin|
|Other common names||-||Synonyms||Anemonia sulcata (Pennant, 1777)|
Recorded distribution in Britain and IrelandPresent on the western coasts of Britain from Portsmouth all around to the west coast of Scotland where it extends northwards to just south of Cape Wrath. Absent from the east basin of the Irish Sea.
HabitatPresent mainly in the intertidal especially in pools from mid-tide downwards but not extending far into the sublittoral. However, frequently present, often in large numbers on the leaves of seagrass (e.g. Zostera marina).
Depth rangeNo text entered
- Base lightly but closely adherent, broader than column.
- Column smooth, disk wide, tentacles long, fairly stout and flexuous - up to about 200.
- Up to 70 mm across the base with a 180 mm tentacle span.
- The column is reddish or greyish brown, the disk brown or greyish with white radial lines, tentacles grey-brown or bright green with purple tips.
- Pale individuals may occur where there is little or no light (for instance when removed to an aquarium).
- Tentacles rarely withdrawn but are capable of withdrawing fully into the column.
Additional informationHowson & Picton (1997) suggest that there is some evidence that the brown form of Anemonia may be a distinct species but this is yet to be confirmed.
