| Corallivorous Drupella (Muricidae) snails at Koh Tao are reported to have extended their range of prey species following a major coral bleaching event in 2010. Populations of their preferred Acropora prey had locally diminished in both size and abundance, and the snails had introduced free-living mushroom corals in their diet. Although the coral community largely recovered, the Drupella population grew and reached outbreak proportions. For this study, corallivorous muricids at Koh Tao were studied more intensively to examine their identities, distribution and prey choice four years after the bleaching event. Drupella rugosa was identified as the major outbreak species and occurred at densities > 3 m-2 in depth ranges of 2-5 and 5-8 m. The density of D.... |

| The mytilid bivalve Fungiacava eilatensis Goreau, Goreau, Neumann & Yonge, 1968, previously mistakenly referred to as F. eilatensis Soot-Ryen, 1969, is reported for the first time from Indonesia. It lives as an obligate endosymbiont of mushroom corals, particulary Fungia spp., reef-dwelling corals restricted to the tropical Indo-Pacific. Notes are given on its association with different host species, its habitat, its biogeography, and its possible competition with endosymbiotic gastropods belonging to the genus Leptoconchus (Coralliophilidae). |

| Bij een inventarisatie van hard substraat in 83 locaties in de Nederlandse Waddenzee, in zoutgehaltes van 10-32 ppt, werden in juli/augustus 2009 in totaal 129 soorten planten en dieren waargenomen. Van deze soorten hadden er 29 een uitheemse of onbekende oorsprong. In aanvulling hierop werd een inventarisatie gemaakt van nog ongepubliceerde waarnemingen in de Waddenzee. Elf soorten en één ondersoort waren nog niet eerder geregistreerd in de Nederlandse Waddenzee. Eén alg, Ceramiaceae sp., met onbekende oorsprong, is vermoedelijk een nieuwe soort voor Europa. Eén zakpijpsoort, Molgula socialis, is nieuw voor Nederland. Deze soort is waarschijnlijk algemeen verspreid in Nederland en is mogelijk zelf inheems. In het verleden was hij vermoedelijk vaak... |

| A new species of coral inhabiting barnacle Cantellius cardenae spec. nov. (Crustacea, Cirripedia: Pyrgomatinae) is described. This barnacle was found on the staghorn coral Acropora (Isopora) brueggemanni (Scleractinia: Acroporidae). It is characterized by having transversally elongated scuta and narrow terga with a spur length more than half of the total tergal length. This species belongs to the secundus group of Cantellius, which includes barnacles with transversally elongated scuta, and which are limited to the Acroporidae. The distribution of C. cardenae supports the hypothesis that structurally specialized pyrgomatines occupy a more limited variety of hosts than do morphologicaly generalized ones. |

| The Raja Ampat expedition in 2007 was organized by the National Museum of Natural History Naturalis in Leiden in cooperation with the Research Centre for Oceanography (RCO-LIPI, Jakarta) as part of Ekspedisi Widya Nusantara (E-Win expedition) of the Indonesian Institute of Sciences (LIPI). The research team consisted of scientists from Indonesia, the Netherlands, Palau and the United States. The Raja Ampat islands are located northwest of Bird’s Head' peninsula in Papua, Indonesia. This area has recently gained much media attention due to its high marine biodiversity and the recent discovery of several new species of corals and fish. The expedition was based at Kri Eco Resort of Papua Diving, on Kri Island. The expedition aimed to study cryptic biota,... |

| Late Quaternary (Eemian) deposits of the Netherlands contain shells that resemble those of living Mytilus galloprovincialis. Similar broad-shelled mytilids also occur in estuaries of the southwestern Netherlands together with slender individuals typical of M. edulis. We sampled living mussels along a depth gradient in the Oosterschelde to a) investigate whether a relation exists between shell shape and depth, b) test if the broadshelled specimens might represent M. galloprovincialis (or a hybrid with M. edulis) and c) assess by inference if the Quaternary specimens might be attributed to M. galloprovincialis as well. In order to do so, we compared genetic (length polymorphism of Me 15/16, COIII sequences and AFLPs) and shellmorphological characteristics... |

| Research on the evolution of the symbiosis between the boring mussel Fungiacava eilatensis (Bivalvia: Mytilidae) and its mushroom coral hosts (Scleractinia: Fungiidae), which requires phylogenetic reconstructions of both the Mytilidae and the Fungiidae, contributes to the understanding of the complexity of coral reef ecosystems. Previously, Fungiacava was regarded as a genus that had descended from Leiosolenus or as belonging to the subfamily Crenellinae, but no phylogenetic support has been obtained for this hypothesis. In the present study, the 18s rRNA sequences of ten mytilid species and the shell microstructures of 12 mytilids were investigated. The phylogenetic position of F. eilatensis is discussed in relation to its associations with its host... |

| Nederland heeft een lange traditie op het gebied van koraalrifonderzoek. Dit heeft deels te maken met het koloniale verleden. Veel van dit type zeeonderzoek kon vroeger worden uitgevoerd in nauwe samenwerking met de Koninklijke Marine, die schepen, oceanografische apparatuur en helmduikers beschikbaar stelde. Deze samenwerking was vooral van belang tijdens onderzoek in afgelegen gebieden. Een ander deel van het vroegere koraalrifonderzoek werd uitgevoerd in de buurt van grote steden, waarbij een kleine boot vaak al voldoende was om ondiepe rifzones te kunnen exploreren. Het Naturalis zeeteam zet de traditie van Nederlands koraalrifonderzoek voort. Sommige van de onderzochte riffen bevinden zich in afgelegen kontreien (Oost-Kalimantan), andere in... |
