sealord > A dahlia anemone, Urticina felina, with a diameter of 5 to 6 cm growing on the side of the rectangular metal float of a pontoon attached to the fish quay in St. Peter Port harbour, Guernsey. This photograph was taken with a Canon S80 digital camera with an underwater housing. Fanworms grow down from the base of the pontoon float. The dahlia anemone is uncommon in Guernsey rock pools on the seashore but the pontoon attached to the fish quay has large numbers of them. Unfortunately, the pontoon is cleaned every four or five years so they will be removed but presumably they will recolonise the cleaned pontoon in time.

sealord > This image shows the hydranth of a hydroid in the genus Ectopleura and most probably the species Ectopleura larynx. There are a similar number of aboral and boral tentacles. The hydroid possesses a collar under the body of the hydranth. This hydroid was photographed in the Queen Elizabeth 2 marina, St. Peter Port harbour, Guernsey on 1 June 2006 using a Canon camera with a 100 mm macro lens and a bellows to increase magnification. The image was taken by leaning over the edge of the pontoon and looking into the water. File No. 30-853 ©RLLord fishinfo@guernsey.net
sealord > The feather duster worm, Sabella spallanzanii, grows in abundance under the pontoons of Guernsey's east coast marinas. This individual, with its feeding tentacles extended, was photographed in Beaucette marina on Guernsey's north-east coast on 31 August 2005. File No. 33-790 ©RLLord fishinfo@guernsey.net
sealord > This tiny anemone, Gonactinia prolifera, is common in the Queen Elizabeth 2 marina, St. Peter Port, Guernsey. This anemone rarely grows larger than 5 mm in height including the tentacles. R.L. Manuel who wrote "British Anthozoa" as part of the Synopses of the British Fauna states "this is the smallest known sea anemone." It is a very active species being able to swim and to move around over the substrate. It reproduces asexually by transverse fission. This image shows the anemone in the process of transverse fission with two sets of tentacles. The base of the column with the shorter tentacles protruding will become another anemone.

sealord > The variegated scallop, Chlamys varia, lives on the side of pontoons in the Queen Elizabeth 2 marina, St. Peter Port harbour, Guernsey. Photographed on 30 August 2005, File No. 300805 36-791 ©RLLord fishinfo@guernsey.net
sealord > The carnivorous Arctic cowrie, Trivia arctica, is common on the pontoons in the Queen Elizabeth 2 marina, St. Peter Port harbour, Guernsey. It feeds on compound sea squirts (ascidians) which grow profusely on the pontoons and attached kelp fronds. Photographed on 19 September 2005 File No. 32-796 ©RLLord fishinfo@guernsey.net
sealord > Dead-man's fingers, Alcyonium digitatum, attach to the base and the corners of the shaded side of the pontoon closest to the mouth of the Queen Elizabeth 2 marina, St. Peter Port, Guernsey. Photographed on 16 September 2006. File No. 160906 34113 ©RLLord fishinfo@guernsey.net
sealord > The palaemonid prawns are abundant in the Queen Elizabeth 2 marina, St. Peter Port, Guernsey. This one was photographed on 25 September 2006. File No. 250906 34124 ©RLLord fishinfo@guernsey.net
sealord > The leathery sea squirt, Styela clava, is a species introduced into British waters from Asian waters probably with military ships returning to the U.K. from the Korean war in 1953. It is common in the Queen Elizabeth 2 marina, St. Peter Port, Guernsey. Photographed on 26 September 2006. File No. 260906 3707 ©RLLord fishinfo@guernsey.net
A dahlia anemone, Urticina felina, with a diameter of 5 to 6 cm growing on the side of the rectangular metal float of a pontoon attached to the fish quay in St. Peter Port harbour, Guernsey. This photograph was taken with a Canon S80 digital camera with an underwater housing. Fanworms grow down from the base of the pontoon float.

The dahlia anemone is uncommon in Guernsey rock pools on the seashore but the pontoon attached to the fish quay has large numbers of them. Unfortunately, the pontoon is cleaned every four or five years so they will be removed but presumably they will recolonise the cleaned pontoon in time.
