On the 19 April 2007 I found two Rostanga rubra nudibranchs under boulders at extreme low water in the centre of Belle Greve Bay on Guernsey's east coast. Rostanga rubra feeds on certain red coloured sponges. File No. 190407 16-899 ©RLLord fishinfo@guernsey.net

Two shore clingfish, Lepadogaster lepadogaster, guard their sheet of eggs, which they have attached to the base of a boulder in Quaine gully in Belle Greve Bay on Guernsey's east coast. Clingfish are well-adapted to living in gullies because their modified pelvic fins allow them to adhere to the substrate so they don't get swept away by strong water flows rushing up and down the gully. The eggs in the sheet have been deposited on two separate occasions as the darker orange eggs are more advanced in development than the pale yellow eggs, which have been laid recently. Photographed on the 17 April 2007. File No. BG 170407 7930 ©RLLord fishinfo@guernsey.net

I believe the orange sponge in the centre of the image is Haliclona simulans. A painted top shell, Calliostoma zizyphinum, sits on the sponge (below the first 'O' in "photography". It grows on the south wall (shaded) of a gully near the Quaine rock pole in Belle Greve Bay on Guernsey's east coast. It was photographed with a Canon S80 compact digital camera at extreme low water during the big equinoctial low tide on 21 March 2007. File No. BG 210307 7550 ©RLLord fishinfo@guernsey.net

This image shows the foot of the turban top shell, Gibbula magus. I turned the snail on its side. The animal extended its foot to quickly turn itself over. This image clearly shows the epipodal tentacles. One eye is hidden behind the 'R' in the Sealord watermark. Dr. Alastair Graham provides a detailed description of the animal in his book "Molluscs: Prosobranch and Pyramidellid Gastropods" published as part of the Synopses of the British Fauna. The following attributes which he writes about can be seen in this photograph: The snout is densely papillated. The epipodal ridge has a scalloped edge. The foot is blunt anteriorly, pointed posteriorly. Its dorsal surface carries many transverse grooves. The umbilicus (which is a deep hole in the base of the shell separate from the opening from which the animal extends from) can be seen above the 'h' in 'Photography'. The umbilicus is large and approached by a comma-shaped groove. Dr. Graham writes that turban top shells "usually live below tidemarks, though rare specimens may be found at L.W.S.T." (low water during a spring tide). This description matches my observations. File No. BG 200307 31-891 ©RLLord fishinfo@guernsey.net
The squat lobster, Galathea nexa, is usually found subtidally but I found a number of them at extreme low water during a big spring tide in Belle Greve Bay on Guernsey's east coast. They were under cobbles in a gully near Quaine rock on 20 March 2007. File No. BG 200307 22-892 ©RLLord fishinfo@guernsey.net
