The surface is covered with irregularly circular craters, containing the inhaling openings. The crater edges are underlined by a clear margin. It lives attached to rocks sometimes in close contact with algae or benthic animals.

Similar to

Phorbas fictitius also has a surface covered with circular craters but their edges are not underlined by a paler margin and they are more regularly placed.The colour of P. fictitius is red, pink or yellowish-grey.
