sealord > This image shows a deposit of eggs of the nudibranch Aeolidia papillosa. Two adult Aeolidia papillosa nudibranchs were seen in the proximity of two deposits of Aeolidia papillosa eggs on the upper shore near the Guernsey end of the Lihou Island causeway on 9 May 2009. Aeolidia papillosa is the largest nudibranch that regularly visits the Guernsey inter-tidal area. It feeds on anemones, particularly beadlet anemones and snakelock anemones, which are both common on the Guernsey shore. File No. 090509 3857 ©RLLord fishinfo@guernsey.net
sealord > I think this flatworm is Cycloporus papillosus. Two individuals were lying on a large colony of the compound ascidian Botryllus schlosseri, on the base of a rock, just south of the Lihou Island causeway. This flatworm was photographed having glided off the ascidian colony on the 9 May 2009. The Botryllus schlosseri colony had been excavated and several deposits of very small eggs were deposited in the depression. I do not know if the flatworms produced the eggs or some other species such as a mollusc. File No. 090509 3943 ©RLLord sealordphotography.net 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 > 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

This image shows a deposit of eggs of the nudibranch Aeolidia papillosa.

Two adult Aeolidia papillosa nudibranchs were seen in the proximity of two deposits of Aeolidia papillosa eggs on the upper shore near the Guernsey end of the Lihou Island causeway on 9 May 2009. Aeolidia papillosa is the largest nudibranch that regularly visits the Guernsey inter-tidal area. It feeds on anemones, particularly beadlet anemones and snakelock anemones, which are both common on the Guernsey shore.
