Its body column is covered with sticky knobs to which sand and debris particles adhere.

The species has a wide range of colours, including pink, brown, green and blue often with a contrastingly-coloured oral disc.

It is found in pools on the lower shore and in crevices on rocks, often huddled into sandy gullies and round the bases of boulders.

It has an extremely strong contractile sphincter muscle which helps it grip and ingest passing food quickly before it is taken away by the waves.

[2] This anemone is larger and particularly abundant in areas where there is strong wave action that tears molluscs from the rocks, and it seems to rely on this turbulence to supply its prey.
