Isaurus cliftoni

This zoanthid is usually encountered in mats on rocky sea floors. It consists of long tubes, with feeding tentacles that can be retracted into the tube. It is usually a dark grey, with a green, blue or brown tinge and pale patches and spots on both the tube and tentacles. This species closely resbembles Zoanthus robustus, which is a plain green without spots. It also differs in that colonies are much less dense, and usually not as large - around 1m maximum diameter.
