Distinguishing features

Colonies can be branching, plate-like or columnar and reach several metres across. The blue skeleton is usually visible but can be hidden by brown-grey tissue. Small (1 mm) polyps with eight tentacles are surrounded by even smaller pores which may bear hairs.

During the day, polyps are usually retracted; close examination of the skeleton will reveal the fine hairs. The colony looks markedly different when the white polyps are extended.
