Recorded distribution in Britain and IrelandCommon around the British Isles with the exception of the east coast of Britain.
Global distributionOccurs around the Channel Islands and on the Atlantic coast of France. Probably does not occur further north than the southern part of the North Sea. Southern limits also uncertain but occurs at least to Biscay.
HabitatOccurs on rocks or other hard substrata, usually on flat surfaces rather than in holes or crevices. Also occurs on various algae such as Laminaria or Himanthalia buttons, and is frequently found in the company of algae, Caryophyllia smithii and the sea anemone Corynactis viridis. Occasionally occurs on the shore in shaded situations but is more commonly found sublittorally down to a depth of about 40 m.
- Uneven translucent dirty white or grey column with longitudinal stripes.
- White, translucent tentacles.
- White or bright yellow/pale orange disc with vague dark markings at tentacle bases.
- Up to 120 tentacles.
- Tentacles span up to 3 cm across the disc.
- Diameter of column base up to 2 cm.
Additional informationMay be confused with Cylista elegans but Actinothoe sphyrodeta lacks the adhesive spots (suckers) on the column present on Cylista elegans. The suckers should not be confused with the cinclides (see Manuel, 1988).
