FAVORITE OPERCULUM by BUNNIE COOK* VOL. XXXVI NO.7 JULY. 1988 NEW SERIES343 FAVORITE OPERCULUM By BUNNIE COOK* One of the first live shells I found in Hawaii many years ago was Nassarius gaudiosus (Hinds, 1844), known then as Nassarius reeveanus (Dunker). I found it during an HMS field trip in a shallow-watertide pool. Although I was fascinatedby the lovely shell and the active animal, it was the operculum that caught my eye - a blood-red arrow dominated the shiny appendageto the foot. I guessthis is why I learned to save opercula right from the start. I was thrilled to find this shell again in April 1987 on the Hawaiian island of Maui. The operculumis still my favorite - a red arrow! Nassarius gaudiosus (Hinds, 1844) from Maui Island, Hawaii. Photos: Burch [E. Alison Kay states in Hawaiian Marine Shells that' 'these nassaridsare common in sandy tide pools and shorewardon fringing reefs." It is interesting, therefore, that long-time HMS collectors Bunnie Cook only collected six, Wes Thorsson eight, and Ray McKinsey six specimens, while Keith Zeilenger, Lyman Higa, Andy Butler and Andy Adams have not collected any. Olive Schoenbergreports, however, that twenty years ago they were common at the boat landing at the Hawaiian Village Hotel in Waikiki. In this connection I wish to thank Dr. Allen Allison, Chairman of the ZoologyDepartment, Bernice P. BishopMuseum in Honoluluwho gave me permission to examine the Museum's shell collection. It has 30 sets of Nas- sarius gaudiosus from throughout the Hawaiian Archipelago all of which were collected in the 1920's and 1930's. These included one set of forty specimens Operculum of Nassarius gaudiosus showing the red arrow. from Paumalu, Oahu, collected in 1936.

    Biodiversity and spatial distribution of molluscs in Tangerang coastal waters, Indonesia 1,2Asep Sahidin, 3Yusli Wardiatno, 3Isdradjad Setyobudiandi 1 Laboratory of Aquatic Resources, Faculty of Fisheries and Marine Science, Universitas Padjadjaran, Bandung, Indonesia; 2 Department of Fisheries, Faculty of Fisheries and Marine Science, Universitas Padjadjaran, Bandung, Indonesia; 3 Department of Aquatic Resources Management, Faculty of Fisheries and Marine Science, IPB University, Bogor, Indonesia. Corresponding author: A. Sahidin, [email protected] Abstract. Tangerang coastal water is considered as a degraded marine ecosystem due to anthropogenic activities such as mangrove conversion, industrial and agriculture waste, and land reclamation. Those activities may affect the marine biodiversity including molluscs which have ecological role as decomposer in bottom waters. The purpose of this study was to describe the biodiversity and distribution of molluscs in coastal waters of Tangerang, Banten Province- Indonesia. Samples were taken from 52 stations from April to August 2014. Sample identification was conducted following the website of World Register of Marine Species and their distribution was analyzed by Canonical Correspondence Analysis (CCA) to elucidate the significant environmental factors affecting the distribution. The research showed 2194 individual of molluscs found divided into 15 species of bivalves and 8 species of gastropods. In terms of number, Lembulus bicuspidatus (Gould, 1845) showed the highest abundance with density of 1100-1517 indv m-2, probably due to its ability to live in extreme conditions such as DO < 0.5 mg L-1. The turbidity and sediment texture seemed to be key parameters in spatial distribution of molluscs. Key Words: bivalve, ecosystem, gastropod, sediment, turbidity. Introduction. Coastal waters are a habitat for various aquatic organisms including macroinvertebrates such as molluscs, crustaceans, polychaeta, olygochaeta and echinodermata.

Physiological responses and scope for growth in a marine scavenging gastropod, Nassarius festivus (Powys, 1835), are affected by salinity and temperature but not by ocean acidification. – ICES Journal of Marine Science, 73: 814–824. Received 4 June 2015; revised 17 September 2015; accepted 19 October 2015; advance access publication 11 November 2015. In the past few years, there has been a dramatic increase in the number of studies revealing negative or positive effects of ocean acidification on marine organisms including corals, echinoderms, copepods, molluscs, and fish. However, scavenging gastropods have received little attention despite being major players in energy flow, removing carrion, and recycling materials in marine benthic communities. The present study investi- gated the physiological responses (ingestion, absorption rate and efficiency, respiration, and excretion) and scope for growth (SfG) of an intertidal scavenging gastropod, Nassarius festivus, to the combined effects of ocean acidification (pCO2 levels: 380, 950, and 1250 matm), salinity (10 and 30 psu), and temperature (15 and 308C) for 31 d.

However, the previous shell or radula-based classification of Nassarius is quite confusing due to the homoplasy of certain morphological characteristics. The toxin accumulators Nassarius glans and Nassarius siquijorensis are widely distributed in the subtidal regions of the Indo-Pacific Ocean. In spite of their biological significance, the phylogenetic positions of N. glans and N. siquijorensis are still undetermined. In the present study, the complete mitochondrial genomes of N. glans and N. siquijorensis were sequenced. The present mitochondrial genomes were 15,296 and 15,337 bp in length, respectively, showing negative AT skews and positive GC skews as well as a bias of AT rich on the heavy strand. They contained 13 protein coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and several noncoding regions, and their gene order was identical to most caenogastropods.

Diversity and distribution of subtidal benthic molluscs from the Dampier Archipelago, Western Australia; results of the 1999 dredge survey (DA2/99) John D. Taylor and Emily A. Glover Department of Zoology, The Natural History Museum, London SW7 5BD, U.K. email: [email protected] [email protected] Abstract - From a dredge survey of the subtidal fauna of the Dampier Archipelago a total of 422 species of macromolluscs was identified, comprising 227 gastropods, 188 bivalves, four scaphopods and three chitons. Most species were uncommon but abundant taxa included the bivalves Melaxinaea vitrea, Corbllla fZlIIlcata and C. crassa and the gastropods Herpetopoma atrata and Xenophora solarioides. Community analysis identified eight molluscan assemblages, reflecting the varied and patchy nature of the substrates that ranged from muds and silts to coarse sands, gravel, rubble and rocks. The most species-rich stations were those located inshore at water depths <10 m. These muddy stations were also notable for the diversity and abundance of suspension-feeding bivalves. Most of the mollusc species identified are distributed widely around tropical Australia and the Indo-West Pacific but a few are endemic to northwestern Australia, including the newly described lucinid bivalve Lamellolllcina pilbara. INTRODUCTION parts of the world. Studies of latitudinal gradients Although the northwestern Australian shelf is of in molluscan diversity usually focus on well­ outstanding biological interest for its suspected high documented continental margins such as the diversity and the relatively high numbers of eastern Pacific coast of North America (Roy, endemic taxa, the subtidal molluscan fauna is Jablonski and Valentine, 2001; Valentine, Roy and poorly known.
