sealord > 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
sealord > This image taken on the southern side of Belle Greve Bay on Guernsey's east coast shows a field of the brown kelp, Laminaria ochroleuca, exposed by an extreme low water spring tide on the 21st March 2007. The Laminaria ochroleuca kelps have cylindrical stipes (or stems). In the middle of the image in the foreground there are some kelps with broad, belt-like stipes. These belong to the furbelows, Laminaria hyperborea. In the background is Salerie Corner and the Salerie quay. File No. BG 210307 7547 ©RLLord fishinfo@guernsey.net
sealord > 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.

sealord > This image shows the lower shore of Belle Greve Bay after ormer (abalone) gatherers have turned over boulders looking for the elusive mollusc. All the pale boulders have been overturned and left upended. Many marine biologists visiting Guernsey from the UK have commented on the damage done to the shore by shore gatherers not returning boulders back to their original position after turning them over to look for the ormer. The tops of the boulders are covered by algae and particularly the pink crustose coralline algae, which issues pheromones which attract settling ormer, Haliotis tuberculata, larvae. The base of boulders are covered in many sessile invertebrate species including spirorbid tubeworms, bryozoan colonies, and ascidian colonies. When boulders and cobbles are turned over and not returned to their original position the algae that were growing on the top die and the invertebrate colonies from the base of the rock die too. The boulder quickly becomes colonised by opportunistic green algae and gradually over time and through succession a more complex community of species adheres to the boulders. If the boulders are turned over too often and the shore suffers too much disturbance macroscopic species diversity deceases. There is a hypothesis that intermediate disturbance allows for the greatest species diversity. File No. BG 210307 30-890 Copyright©RLLord fishinfo@guernsey.net Boulders turned over BG 210307 30-890
sealord > 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.

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.
