Diversity of Norwegian Sea Slugs (Nudibranchia): New Species to Norwegian Coastal Waters and New Data on Distribution of Rare Species
Fauna norvegica 2013 Vol. 32: 45-52. ISSN: 1502-4873 Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species Jussi Evertsen1 and Torkild Bakken1 Evertsen J, Bakken T. 2013. Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species. Fauna norvegica 32: 45-52. A total of 5 nudibranch species are reported from the Norwegian coast for the first time (Doridoxa ingolfiana, Goniodoris castanea, Onchidoris sparsa, Eubranchus rupium and Proctonotus mucro- niferus). In addition 10 species that can be considered rare in Norwegian waters are presented with new information (Lophodoris danielsseni, Onchidoris depressa, Palio nothus, Tritonia griegi, Tritonia lineata, Hero formosa, Janolus cristatus, Cumanotus beaumonti, Berghia norvegica and Calma glau- coides), in some cases with considerable changes to their distribution. These new results present an update to our previous extensive investigation of the nudibranch fauna of the Norwegian coast from 2005, which now totals 87 species. An increase in several new species to the Norwegian fauna and new records of rare species, some with considerable updates, in relatively few years results mainly from sampling effort and contributions by specialists on samples from poorly sampled areas. doi: 10.5324/fn.v31i0.1576.

Seasearch Seasearch Wales 2012 Summary Report Summary Report
Seasearch Wales 2012 Summary Report report prepared by Kate Lock, South and West Wales coco----ordinatorordinator Liz MorMorris,ris, North Wales coco----ordinatorordinator Chris Wood, National coco----ordinatorordinator Seasearch Wales 2012 Seasearch is a volunteer marine habitat and species surveying scheme for recreational divers in Britain and Ireland. It is coordinated by the Marine Conservation Society. This report summarises the Seasearch activity in Wales in 2012. It includes summaries of the sites surveyed and identifies rare or unusual species and habitats encountered. These include a number of Welsh Biodiversity Action Plan habitats and species. It does not include all of the detailed data as this has been entered into the Marine Recorder database and supplied to Natural Resources Wales for use in its marine conservation activities. The data is also available on-line through the National Biodiversity Network. During 2012 we continued to focus on Biodiversity Action Plan species and habitats and on sites that had not been previously surveyed. Data from Wales in 2012 comprised 192 Observation Forms, 154 Survey Forms and 1 sea fan record. The total of 347 represents 19% of the data for the whole of Britain and Ireland. Seasearch in Wales is delivered by two Seasearch regional coordinators. Kate Lock coordinates the South and West Wales region which extends from the Severn estuary to Aberystwyth. Liz Morris coordinates the North Wales region which extends from Aberystwyth to the Dee. The two coordinators are assisted by a number of active Seasearch Tutors, Assistant Tutors and Dive Organisers. Overall guidance and support is provided by the National Seasearch Coordinator, Chris Wood. -
Mollusc World Magazine
IssueMolluscWorld 24 November 2010 Glorious sea slugs Our voice in mollusc conservation Comparing Ensis minor and Ensis siliqua THE CONCHOLOGICAL SOCIETY OF GREAT BRITAIN AND IRELAND From the Hon. President Peter has very kindly invited me to use his editorial slot to write a piece encouraging more members to play an active part in the Society. A few stalwarts already give very generously of their time and energy, and we are enormously grateful to them; but it would be good to spread the load and get more done. Some of you, I know, don’t have enough time - at least at the moment - and others can’t for other reasons; but if you do have time and energy, please don’t be put off by any reluctance to get involved, or any feeling that you don’t know enough. There are many ways in which you can take part – coming to meetings, and especially field meetings; sending in records; helping with the records databases and the website; writing for our publications; joining Council; and taking on one of the officers’ jobs. None of us know enough when we start; but there’s a lot of experience and knowledge in the Society, and fellow members are enormously helpful in sharing what they know. Apart from learning a lot, you will also make new friends, and have a lot of fun. The Society plays an important part in contributing to our knowledge of molluscs and to mollusc conservation, especially through the database on the National Biodiversity Network Gateway (www.nbn.org.uk); and is important also in building positive links between professional and amateur conchologists. -

On the Structure and Function of the Wandering Cells in the Wall of the Alimentary Canal of Nudi- Branchiate Mollusca
4°5 ON THE STRUCTURE AND FUNCTION OF THE WANDERING CELLS IN THE WALL OF THE ALIMENTARY CANAL OF NUDI- BRANCHIATE MOLLUSCA BY NORMAN MILLOTT, M.Sc. Demonstrator in Zoology, the Victoria University of Manchester (Received 17 December 1936) (With Five Text-figures) INTRODUCTION IN the lining epithelium and subjacent tissues of the gut of nudibranch molluscs are certain wandering cells. These differ from the lymphocytes, which are also present in the epithelium, submucosa, and underlying blood spaces of the gut, in being somewhat larger; though both types of cell are very variable in size. Unlike the lymphocytes, these cells possess a very definite, almost corpuscular, form after fixation. They are rare in the general vascular system, being largely confined to the wall and lumen of the gut. In the majority of animals examined, they appeared most numerous in the hindgut. In the gut epithelium of all the forms examined, the wandering cells often occupied spacious cavities. Figs. 2-5 indicate the uniformity of appearance of the wandering cells, and the characteristic manner in which they occur in intra-epithelial spaces (int.ep.c). The following investigation aims at discovering whether these cells have any significance in the excretory processes of nudibranchs. The term "excretion" is used in its widest sense. No attempt is made to dis- tinguish between water excretion, nitrogen excretion, or the elimination of other, by- or end-products of metabolism. I wish to express my gratitude to Prof. H. Graham Cannon, for the great help he has given me in the preparation of this paper. My thanks are also due to Dr C. -
Manacles MCZ Report
Se a se a r ch surveys wit hin and adjacent to the Manacles Marine Conservation Zone 2001-2015 Ch r i s Wood 50 ACKN OWLEDGEMENTS Se a se a r ch would like to thank all of the volunteer divers over the years who have contributed to the records made in the Manacles area. Many of them have been individuals but organised dives have also been carried out organised by t he Marine Conservation Society and Cornwall Wildlife Trust. Many of the dives have been from local boats and we thank both Dive Action and Porthkerris Dive Centre for taking us to the sites surveyed. In 2015 all of the boat surveys were organised by Porthkerris Dives Centre and we would like to thank Mike and Jo Anselmi for their valuable support for these surveys. Almost all of the records made were by Seasearch volunteers. However the Wildlife Trusts organised one day of diving using a professional (but Seasearch t rained) team and we thank them for access to their records. Dr Matthew Witt, Environment and Sustainabilit y Institute, Universit y of Exeter, produced the maps throughout this report. We would like to thank those who have contributed photographs or t his report. They are Mark Webster, Tony Sutton, Sally Sharrock and Porthkerris Dive Centre. Other photographs are by the author. Fi nal l y t he aut hor w ould like to thank Dr Charlotte Bolton (Seasearch), Dr Jean-Luc Solandt (Marine Co n se r vation Society), Dr Matthew Witt (Exeter Universit y) and M ike Anselmi (Porthkerris Dive Centre) for their reading of and contributions to this report. -

Inspiring people. Seasearch Report for 2010 Hampshire and Isle of Wight Wildlife Trust During 2010, Hampshire and Isle of Wight Wildlife Trust (HIWWT) continued to run a successful Seasearch programme. We organised five dive days in which 31 divers undertook a total of 40 individual dives across 9 different sites. One diver also sent in a form from a privately organised dive resulting in a total of 10 sites in all being surveyed in the Hampshire and Isle of Wight area (Table 1, Figure 1), and 63 forms submitted. The areas surveyed included sand and gravel, and seagrass beds (both Biodiversity Action Plan habitats), mixed ground, wrecks and soft mud. In total 168 species, representing 12 phyla, were recorded (Table 2). HIWWT also continued to train divers by delivering two Observer courses with a total of 25 participants. In addition, we provided assistance on dive days privately organised by our course participants in Dorset and Sussex as part of their in-water Observer training. Forms generated by these dives were passed on to the appropriate Seasearch county co- ordinators. Table 1. Hampshire and Isle of Wight sites surveyed in 2010.

ABSTRACT Contribution to the study of the metamorphosis in Nudi- branches. A careful study of the organogenesis ofÆolidiella alderi has been made. Other unknown ontogenic cases have been observed and compared with. Normal and teratological organogenesis, comparative anatomy lead to a discussion which particularly concerns phylogeny of Nudibranches.
