Additional InformationMay be confused with Alcyonium glomeratum, which prefers sites sheltered from wave action or tidal streams. It is blood red or rust coloured (occasionally pale orange or yellowish), has relatively slender branches, and a softer, more flaccid texture but a rough surface. In Alcyonium glomeratum the colonies are also more contractile, and cross sections through the fingers show numerous cavities.
