sealord > This gully is by the Quaine pole (the top of the pole has a large letter 'Q') in Belle Greve Bay on Guernsey's east coast so I call it Quaine gully. It can only be reached by foot during an extreme low spring tide. This gully is home to clingfishes ( See http://sealord.smugmug.com/gallery/1984411#145028125 ), rocklings, squat lobsters (Galathea nexa), hermit crabs, ormers or abalone and many other occasional species such as the snapping prawn, Alpheus macrocheles (See http://sealord.smugmug.com/gallery/1984411#139498411 ). The walls of the gully are covered in crustose coralline algae and draped with thongweed, Himanthalia elongata and Laminaria kelps. The walls are also covered in a variety of sponges. Some of the crevices and holes in the gully walls contain Devonshire cup corals and sponges that avoid light. File No. BG 170407 7955 ©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
