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.

Netted dog whelk, Hinia reticulata, egg cases attached to eel grass, Zostera marina, on the beach in Belle Greve Bay, on Guernsey's east coast. This photograph was taken on the beach where the eel grass remained submerged in a sheltered pool. Many of the eel grass leaves carried these egg cases. These egg cases had been deposited recently, since the last set of spring tides around the 5th of March 2007.  These egg cases had all appeared on the eel grass leaves by the series of spring tides around 20 March 2007.  Photographed in Belle Greve Bay on the 21 March 2007.

The low tide of 20 February 2007 revealed eel grass, Zostera marina, beds in Belle Greve Bay.  These beds stabilise the beach.  Within and underneath these eel grass beds there are razor clams, otter shells, sea potatoes and mask crabs.  Many molluscs feed and lay their eggs on the eel grass leaves.  Sea spiders, crabs, shrimp and sea anemones live in amongst the plants.

Jujubinus striatus eel grass BG 051106 32-869 smg
The small snails, Rissostomia membranacea, somehow remain attached to the leaves of eel grass, Zostera marina, even while the eel grass leaves are being pulled from one side to another by the surf and currents of the seashore.  This gastropod was found on eel grass at the southern end of Belle Greve Bay on Guernsey's east coast and photographed on 5 November 2006

The lesser sandeel, Ammodytes tobianus, often buries itself in the sand on the lower shore of the beach when the tide goes out.  This one was lifted out of the sand with a fork by a recreational bait digger. Sandeels will rebury themselves if given the opportunity.  This individual was captured and released near eel grass beds on the lower shore of Belle Greve Bay on 29 March 2006.

Although these particular netted dog whelk, Hinia reticulata, egg cases were not from Belle Greve Bay, I have seen these egg cases attached to the eel grass growing on the sandy shore of Belle Greve Bay.
