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.

17 September 2009 Nudibranch Systematic Index page - 1 NUDIBRANCH SYSTEMATIC INDEX Second Online Edition compiled by Gary McDonald 17 September 2009 Gary McDonald, Long Marine Lab, 100 Shaffer Rd., Santa Cruz, Cal. 95060 17 September 2009 Nudibranch Systematic Index page - 2 This is an index of the more than 7,000 nudibranch reprints and books in my collection. I have indexed them only for information concerning systematics, taxonomy, nomenclature, & description of taxa (as these are my areas of interest, and to have tried to index for areas such as physiology, behavior, ecology, neurophysiology, anatomy, etc. would have made the job too large and I would have given up long ago). This is a working list and as such may contain errors, but it should allow you to quickly find information concerning the description, taxonomy, or systematics of almost any species of nudibranch. The phylogenetic hierarchy used is based on Traite de Zoologie, with a few additions and changes (since this is intended to be an index, and not a definitive classification, I have not attempted to update the hierarchy to reflect recent changes). The full citation for any of the authors and dates listed may be found in the nudibranch bibliography at http://repositories.cdlib.org/ims/Bibliographia_Nudibranchia_second_edition/. Names in square brackets and preceded by an equal sign are synonyms which were listed as such in at least one of the cited papers. If only a generic name is listed in square brackets after a species name, it indicates that the generic allocation of the species has changed, but the specific epithet is the same. -
Spongivory by Nudibranchs on the Coast of Rio De Janeiro State, Southeastern Brazil

Spongivory by nudibranchs on the coast of Rio de Janeiro state, southeastern Brazil (Mollusca, Gastropoda). Spixiana 38 (2): 187-195. Nudibranch gastropods are carnivores and most dorid nudibranchs are spongi- vores, preying on a single or a few species of sponges. The feeding biology has important biological, ecological and evolutionary implications, and many charac- teristics of nudibranchs likely arose from co-evolution with diet organisms. Data on spongivory by dorid nudibranchs are available for many species from the Indo- Pacific, eastern Pacific and the Mediterranean Sea, but such information is scarce for the southwestern Atlantic. In this study we provide qualitative data on spongi- vory by dorid nudibranchs along the coast of Rio de Janeiro State, southeastern Brazil, including the identification of the species involved. A total of 94 spongi- vory events were observed between 12 nudibranch and 13 sponge species, greatly expanding our knowledge of predator-prey interactions. Among the sponges preyed upon, one species belongs to the class Homoscleromorpha (Plakina sp.) and 12 species to the class Demospongiae. Our observations show that spongivorous nudibranchs have a more diverse diet than previously thought. Additional observa- tions on a higher number of species from different biogeographic regions are needed for a better understanding of the feeding preferences of the diverse and ecologically important spongivorous dorid nudibranchs. -

Goddard Abstract: Mode of development was determined for 130 of the nearly 250 species of shallow-water, benthic opistho- branchs known from the northeast Pacific Ocean. Excluding four introduced or cryptogenic species, 91% of the species have planktotrophic development, 5% have lecithotrophic development, and 5% have direct development. Of the 12 na- tive species with non-feeding (i.e., lecithotrophic or direct) modes of development, 5 occur largely or entirely south of Point Conception, California, where surface waters are warmer, lower in nutrients, and less productive than those to the north; 4 are known from habitats, mainly estuaries, that are small and sparsely distributed along the Pacific coast of North America; and 1 is Arctic and circumboreal in distribution. The nudibranchs Doto amyra Marcus, 1961 and Phidiana hiltoni (O’Donoghue, 1927) were the only species with non-feeding development that were widespread along the outer coast. This pattern of distribution of developmental mode is consistent with the prediction that planktotrophy should be maintained at high prevalence in regions safe for larval feeding and growth and should tend to be selected against where the risks of larval mortality (from low- or poor-quality food, predation, and transport away from favor- able adult habitat) are higher. -

Conids are well known for being active predators on worms, fishes, and even other snails. Cones are venomous gastropods, meaning that they use a sophisticated cocktail of hundreds of toxins, named conotoxins, to subdue their prey. Although this venom has been studied for decades, most of the effort has been focused on Indo-Pacific species. Thus far, Atlantic species have received little attention despite recent radiations have led to a hotspot of diversity in West Africa, with high levels of endemic species. In fact, the Atlantic Chelyconus ermineus is thought to represent an adaptation to piscivory independent from the Indo-Pacific species and is, therefore, key to understanding the basis of this diet specialization. We studied the transcriptomes of the venom gland of three individuals of C. ermineus. The venom repertoire of this species included more than 300 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity. -
Common Seashore Animals of Southeastern Alaska a Field Guide by Aaron Baldwin
Common seashore animals of Southeastern Alaska A field guide by Aaron Baldwin All pictures taken by Aaron Baldwin Last update 9/15/2014 unless otherwise noted. [email protected] Seashore animals of Southeastern Alaska By Aaron Baldwin Introduction Southeast Alaska (the “Alaskan Panhandle”) is an ecologically diverse region that extends from Yakutat to Dixon Entrance south of Prince of Wales Island. A complex of several hundred islands, fjords, channels, and bays, SE Alaska has over 3,000 miles of coastline. Most people who live or visit Southeast Alaska have some idea of the incredible diversity of nature found here. From mountain tops to the cold, dark depths of our many fjords, life is everywhere. The marine life of SE Alaska is exceptionally diverse for several reasons. One is simply the amount of coast, over twice the amount of the coastline of Washington, Oregon, and California combined! Within this enormous coastline there is an incredible variety of habitats, each with their own ecological community. Another reason for SE Alaska’s marine diversity is that we are in an overlap zone between two major faunal provinces. These provinces are defined as large areas that contain a similar assemblage of animals. From northern California to SE Alaska is a faunal province called the Oregonian Province. From the Aleutian Island chain to SE Alaska is the Aleutian Province. What this means is that while our sea life is generally similar to that seen in British Columbia and Washington state, we also have a great number of northern species present.
