Opisthobranch Mollusks from the Southern Tropical Pacific' ERNST MARCUS and EVELINE MARCUS2 Opisthobranch Mollusks from the Southern Tropical Pacific' ERNST MARCUS and EVELINE MARCUS2 ABSTRACT : Twenty-four species of opisthobranchs are listed from the southern tropical Pacific Ocean, from Fiji and the Ellice Islands eastward to the Tuamotus. Two new genera are described: Pleurebdera (Pleurobranchidae; type species: P. haraldi n. sp., Tuamotus) and Pllpsiklls (Dorididae; type species: P. pingllis n. sp., Tahiti). Th e following five other new species and subspecies are described and figured : N oumea norba (Dorididae: Chromodoridinae, Viti Levu, Fiji) ; Perono­ doris rebderi (Dorididae: Archidoridinae, Tahiti); Tayuo« ketos jllva (Dorididae: Discodoridinae, Rurutu , Tubuai Islands) ; Phyllidia tula (Phyllidiidae, Nukulaelae, Ellice Islands) ; Phyllidia soria (Tahiti) . The internal anatomy of these species, as well as of many of the previously known species, is described. Many species are recorded from Polynesia for the first time. THE OPISTHOBRANCH MOLLUSKS discussed in and return of this collection through the kind this paper were sent to us for classification by offices of the U. S. General Consulate in Sao Dr. Harald A. Rehder, Smithsonian Institution, Paulo. W ashington, D. C. They were gathered by Dr. Rehder and his collectors in the tropical southern Pacific in an area centering in the LIST OF OPISTHOBRAN CHS DISCUSSED Society Islands and the neighboring Tubu ai Order Anaspid ea Islands.

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.

  • Nudibranch Neighborhood: the Distribution of Two Nudibranch Species (Chromodoris Lochi and Chromodoris Sp.) in Cook’S Bay, Mo’Orea, French Polynesia Gwen Hubner
    NUDIBRANCH NEIGHBORHOOD: THE DISTRIBUTION OF TWO NUDIBRANCH SPECIES (CHROMODORIS LOCHI AND CHROMODORIS SP.) IN COOK’S BAY, MO’OREA, FRENCH POLYNESIA GWEN HUBNER Anthropology, University of California, Berkeley, California 94720 USA Abstract. Benthic invertebrates are vital not only for the place they hold in the trophic web of the marine ecosystem, but also for the incredible diversity that they add to the world. This is especially true of the dorid nudibranchs (family Dorididae), a group of specialist predators that are also the most diverse family in a clade of shell-less gastropods. Little work has been done on the roles that environment and behavior play on distribution patterns of dorid nuidbranchs. By carrying out habitat surveys, I found that two species of dorid nudibranchs (Chromodoris lochi and Chromodoris sp.) occupy different habitats in Cook’s Bay. Behavioral interaction tests showed that both species orient more reliably toward conspecifics than toward allospecifics. C. lochi has a greater propensity to aggregate than Chromodoris sp. These findings indicated that the distribution patterns are a result of both habitat preference and aggregation behaviors. Further inquiry into these two areas is needed to make additional conclusions on the forces driving distribution. Information in this area is necessary to inform future conservation decisions. Key words: dorid nudibranchs; Chromodoris lochi; behavior; environment INTRODUCTION rely on sponges for survival in three interconnected ways: as a food source and for Nudibranchs (order Nudibranchia), a their two major defense mechanisms. This diverse clade of marine gastropods, are dependence on specialized prey places dorid unique marine snails that have lost a crucial nudibranchs in an important role in the food means of protection-- their shell.

Also, Noumea purpurea Baba, 1949 was re-described with illustrations because previous records for this species were given without a description. Two congeneric species in the genus Noumea could be distinguished by ground color, dorsal markings, color of the mantle edge and gills, and mantle and dorsal marking. In addition, mitochondrial cytochrome c oxidase subunit I (COI) sequences of five species were provided for further molecular identification study. Consequently, a total of 43 species have been reported for the Korean nudi- branch fauna.

Calumpong 2 1 International Center for LivingAquatic Resources Management (ICLARM); MCC P.O. Box 1501,Makati, Metro Manila, Philippines 2 Marine Laboratory, Silliman University; Dumaguete City, Philippines Abstract Material and methods The growth parameters WIX) and K of the von Bertalanff)r The growth equation used here to describe the growth of growth equation were estimated from size-frequency data Dolabella auricularia is the well-known von Bertalanff)r of the sea hare Dolabella auricularia using an objective, growth function (VBGF) (for weight growth): computer-based method. The results obtained from two W1= W IX)(1_e-K(t-to»3 . (1) locations in the central Philippines were comparable, although based on only a few individuals; the means for The exponent in Eq. (1) assumes that growth is isometric, both sites were WIX)=493g and K=0.9 (yearly basis). A i.e. that weight is proportional to length cubed. Since it is value of Z = 3.66, corresponding to an annual survival rate extremely difficult to take consistent linear measurements of 2.6%,was estimated for the juveniles and adults from a in aplysiid gastropods (which lack hard parts), the proce- length-converted catch curve. Spawning and recruitment dure used here was to take the cubic root of weights and were found to occur throughout the year with peaks in to treat them - under the assumption of isometry - as May to July and September to October.
