sealord > I think this flatworm is Cycloporus papillosus. Two individuals were lying on a large colony of the compound ascidian Botryllus schlosseri, on the base of a rock, just south of the Lihou Island causeway. This flatworm was photographed having glided off the ascidian colony on the 9 May 2009. The Botryllus schlosseri colony had been excavated and several deposits of very small eggs were deposited in the depression. I do not know if the flatworms produced the eggs or some other species such as a mollusc. File No. 090509 3943 ©RLLord sealordphotography.net fishinfo@guernsey.net
sealord > This bryozoan colony, Watersipora subtorquata, was discovered in the Queen Elizabeth II marina, St. Peter Port harbour, Guernsey, Channel Islands on 30 May 2007. It was growing attached to the south side of a pontoon next to the south wall of the marina. This species is an invasive species that probably arrived on a boat's hull from France. It is native to the western Atlantic and the Caribbean. It has already been introduced to the Californian coast of the Pacific Ocean. This image shows the feeding lophophores extended. This specimen was identified by John Ryland, Emeritus Professor of Marine Biology at the University of Wales Swansea, and Dr. Joshua Mackie of the Moss Landing Marine Laboratories, California, USA.

sealord > This colony of the bryozoan Watersipora subtorquata is the first record of this species in the British Isles. It was found growing on the south side of a pontoon running along the southern wall of the Queen Elizabeth II marina in St. Peter Port, Guernsey, Channel Islands on 30 May 2007. John Ryland, Emeritus Professor of Marine Biology, from the University of Wales Swansea and Dr. Joshua Mackie from Moss Landing Marine Laboratories in California identified the species for me. This species may have been found since the initial discovery in Plymouth, England by Dr. John Bishop on the hull of a beached ship. This species is native to the western Atlantic and the Caribbean.

sealord > 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. File No. 110704 13-745
sealord > A close-up view of zooids of the bryozoan, Flustrellidra hispida, which was growing on the surface of the brown seaweed, serrated wrack, Fucus serratus, at La Valette on Guernsey's east coast on 1 August 2003. Some of the zooids have extended their lophophores (bell-shaped ring of ciliated tentacles) to feed. File No. 010803 13-682 ©RLLord fishinfo@guernsey.net

I think this flatworm is Cycloporus papillosus. Two individuals were lying on a large colony of the compound ascidian Botryllus schlosseri, on the base of a rock, just south of the Lihou Island causeway. This flatworm was photographed having glided off the ascidian colony on the 9 May 2009. The Botryllus schlosseri colony had been excavated and several deposits of very small eggs were deposited in the depression. I do not know if the flatworms produced the eggs or some other species such as a mollusc.
