Since the last set of spring tides (4 to 6 March 2007) netted dog whelks, Hinia reticulata, had laid many egg capsules on eel grass, Zostera marina, in Belle Greve Bay on Guernsey's east coast.

The eel grass beds are subtidal during neap tides but they are exposed during big low spring tides. These occurred from 19 to 22 March. During low water I saw a large number of netted dog whelk egg capsules attached to eel grass that occurred in a shallow pool on the beach in Belle Greve Bay. Photographed on the 21 March 2007.

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.

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.

A young ormer or abalone, Haliotis tuberculata, crawling over crustose coralline algae on a boulder in Belle Greve Bay on Guernsey's east coast on 4 February 2007. This animal was smaller than the legal size (8 cm shell length) to harvest ormers during the Guernsey ormer gathering season.
