Raphitoma purpurea coralline pool BG 180407 9-899 smg

Raphitoma purpurea coralline pool BG 180407 5-899 smg

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.

Aeolidia papillosa repro Coralline pool BG 020407 7829 smg

A selection of marine life found in Belle Greve Bay on Guernsey's east coast.
Top row left to right:
sea anemone prawn, Periclimenes sagittifer, found on the snakelocks anemone, Anemonia viridis, in Belle Greve Bay on the 20 March 2007.
The nudibranch, Janolus hyalinus, found under a boulder covered in crustose coralline algae in a mid-shore tide pool on the 17 February 2007; and a masked crab, Corystes cassivelaunus, dug up from the beach and photographed on the 20 February 2007.
Middle row left to right:
A sand goby, Pomatoschistus minutus, buried in the sand and photographed on the 20 February 2007; a candy-striped flatworm, Prostheceraeus vittatus, photographed in a tide pool on the 5 February 2007; and a female worm pipefish, Nerophis lumbriciformis.
Bottom row left to right: long-spined sea scorpion (a
sculpin), Taurulus bubalis, photographed in a tide pool on the 4 February 2007; the nudibranch, Hermaea bifida photographed on the 15 February 2006; and a stalked jellyfish, Haliclystus auricula, attached to eel grass, Zostera marina and photographed on the 5 November 2006.

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.

Normally the snapping prawn, Alpheus macrocheles, is found subtidally but this individual was found under a cobble in a gully by Quaine rock in Belle Greve Bay on Guernsey's east coast. It was found at extreme low water during a big spring tide on 20 March 2007.

The snapping prawn is well-named for the loud sound it can make when alarmed. It makes this sound by snapping the heavy dactyl of the left claw against the propodus, which causes a cavitation in the water. The startling sound resembles a cluck that can be made by moving ones tongue over the roof of the mouth.

The live turban top shell, Gibbula magus, was found on the beach in Belle Greve Bay on Guernsey's east coast on 20 March 2007. This is the first live individual I have seen in Guernsey. Empty turban top shells are quite common on Chouet beach in Ladies Bay on Guernsey's north coast. The tentacles of a worm, possibly a spionid worm, may be sticking out of the top of the snail shell but I need to contact a specialist to verify this.

This photograph of a small stone from Belle Greve Bay, Guernsey covered in crustose coralline algae shows various holes. The larger dark holes are made by the polychaete worm Polydora sp., which is in the family spionidae. These burrowing or tube-forming worms have long filaments or palps attached to the head, which extend out of the holes they make. A pair of palps can be seen in the upper right-hand corner of the image. They appear as thin white lines. The smaller holes ringed with white are reproductive structures of the red algae.
