The arms are either brown or red and white with the colour in large patches rather than the freckled appearance of Antedon bifida. There are more cirri, about 50-100 arising around a low hemispherical plate, and the lower side of the arm has an almost smooth outline. Arms typically 7-10cm in length.
Habitat: Found mostly in sheltered habitats attached to kelp, sessile animals or directly to wrecks or boulders.
Distribution: A northern species in the British Isles, at least in shallow water, frequent in the northern part of the Irish Sea and inshore in the west of Scotland, also around Shetland.
