Ross coral, Pentapora fascialis, grows in the Little Russel, which is the sea channel between Guernsey and Herm off Guernsey's capital, St. Peter Port. The zooids form heavily calcified bilaminar plates that intersect to produce a three-dimensional solid but brittle structure that resembles a coral head (phylum cnidaria) hence the common name. This colony was growing on a cobble on the seafloor. It had a width of about 30 cm. These colonies can live 12 years. It was photographed on 11 July 2004.
