The Chiton Radula: a Unique Model for Biomineralization Studies
4 The Chiton Radula: A Unique Model for Biomineralization Studies Lesley R. Brooker1 and Jeremy A. Shaw2 1University of the Sunshine Coast 2Centre for Microscopy, Characterisation & Analysis University of Western Australia Australia 1. Introduction Over the course of evolution, a range of strategies have been developed by different organisms to produce unique materials and structures perfected for their specific function. This biological mastery of materials production has inspired the birth of the new discipline of biomaterials through biomimicry (Birchall, 1989). Chitons (Mollusca: Polyplacophora) are slow moving, bilaterally symmetrical and dorso- ventrally flattened molluscs that are commonly found on hard substrata in intertidal regions of coastlines around the world (Kaas & Jones, 1998). All species are characterized by a series of eight dorsal, articulating shell plates or valves, which may be embedded, to varying degrees, in a fleshy, muscular girdle (Kaas & Jones, 1998) (Figure 1). Approximately 750 living species are known, and while intertidal regions are home to the majority of chitons, a number of species can be found at depths of up to 8000m where they feed on detrital material (Kaas & Jones, 1998). Fig. 1. Photograph of the dorsal surface of the chiton Acanthopleura gaimardi, showing the eight overlapping aragonite plates surrounded by the fleshy girdle, which, in this species, is covered in small aragonite spines. Chitons feed by rasping macro- and micro-algae from the rocks on which they live through the use of a radula. The radula has been coined as a conveyor belt of continuously developing www.intechopen.com 66 Advanced Topics in Biomineralization teeth, replaced by new teeth as they are worn and lost. -

Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998
Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998 Stephen A. Grabe Environmental Supervisor David J. Karlen Environmental Scientist II Christina M. Holden Environmental Scientist I Barbara Goetting Environmental Specialist I Thomas Dix Environmental Scientist II MARCH 2003 1 Environmental Protection Commission of Hillsborough County Richard Garrity, Ph.D. Executive Director Gerold Morrison, Ph.D. Director, Environmental Resources Management Division 2 INTRODUCTION The Environmental Protection Commission of Hillsborough County (EPCHC) has been collecting samples in Middle Tampa Bay 1993 as part of the bay-wide benthic monitoring program developed to (Tampa Bay National Estuary Program 1996). The original objectives of this program were to discern the ―health‖—or ―status‖-- of the bay’s sediments by developing a Benthic Index for Tampa Bay as well as evaluating sediment quality by means of Sediment Quality Assessment Guidelines (SQAGs). The Tampa Bay Estuary Program provided partial support for this monitoring. This report summarizes data collected during 1993-1998 from the Middle Tampa Bay segment of Tampa Bay. 3 METHODS Field Collection and Laboratory Procedures: A total of 127 stations (20 to 24 per year) were sampled during late summer/early fall ―Index Period‖ 1993-1998 (Appendix A). Sample locations were randomly selected from computer- generated coordinates. Benthic samples were collected using a Young grab sampler following the field protocols outlined in Courtney et al. (1993). Laboratory procedures followed the protocols set forth in Courtney et al. (1995). Data Analysis: Species richness, Shannon-Wiener diversity, and Evenness were calculated using PISCES Conservation Ltd.’s (2001) ―Species Diversity and Richness II‖ software. -
Taxonomy of Tropical West African Bivalves V. Noetiidae
Bull. Mus. nati. Hist, nat., Paris, 4' sér., 14, 1992, section A, nos 3-4 : 655-691. Taxonomy of Tropical West African Bivalves V. Noetiidae by P. Graham OLIVER and Rudo VON COSEL Abstract. — Five species of Noetiidae are described from tropical West Africa, defined here as between 23° N and 17°S. The Noetiidae are represented by five genera, and four new taxa are introduced : Stenocista n. gen., erected for Area gambiensis Reeve; Sheldonella minutalis n. sp., Striarca lactea scoliosa n. subsp. and Striarca lactea epetrima n. subsp. Striarca lactea shows considerable variation within species. Ecological factors and geographical clines are invoked to explain some of this variation but local genetic isolation could not be excluded. The relationships of the shallow water West African noetiid species are analysed and compared to the faunas of the Mediterranean, Caribbean, Panamic and Indo- Pacific regions. Stenocista is the only genus endemic to West Africa. A general discussion on the relationships of all the shallow water West African Arcoidea is presented. The level of generic endemism is low and there is clear evidence of circumtropical patterns of similarity between species. The greatest affinity is with the Indo-Pacific but this pattern is not consistent between subfamilies. Notably the Anadarinae have greatest similarity to the Panamic faunal province.

(Mollusca: Gastropoda). – Spixiana 30/1: 121-125 The higher systematics of the family Ovulidae is reorganised on the basis of re- cently published studies of the radulae, shell and animal morphology and the 16S rRNA gene. The family is divided into four subfamilies. Two new subfamilîes are introduced as Prionovolvinae nov. and Aclyvolvinae nov. The apomorphism and the result of the study of the 16S rRNA gene are contro- versally concerning the Pediculariidae. Therefore, the Pediculariidae are excluded as subfamily from the Ovulidae.

Nearshore Marine Biodiversity of the Sunshine Coast, South-East Queensland: Inventory of molluscs, corals and fishes July 2010 Photo courtesy Ian Banks Baseline Survey Report to the Noosa Integrated Catchment Association, September 2010 Lyndon DeVantier, David Williamson and Richard Willan Executive Summary Nearshore reef-associated fauna were surveyed at 14 sites at seven locations on the Sunshine Coast in July 2010. The sites were located offshore from Noosa in the north to Caloundra in the south. The species composition and abundance of corals and fishes and ecological condition of the sites were recorded using standard methods of rapid ecological assessment. A comprehensive list of molluscs was compiled from personal observations, the published literature, verifiable unpublished reports, and photographs. Photographic records of other conspicuous macro-fauna, including turtles, sponges, echinoderms and crustaceans, were also made anecdotally. The results of the survey are briefly summarized below. 1. Totals of 105 species of reef-building corals, 222 species of fish and 835 species of molluscs were compiled. Thirty-nine genera of soft corals, sea fans, anemones and corallimorpharians were also recorded. An additional 17 reef- building coral species have been reported from the Sunshine Coast in previous publications and one additional species was identified from a photo collection. 2. Of the 835 mollusc species listed, 710 species could be assigned specific names. Some of those not assigned specific status are new to science, not yet formally described. 3. Almost 10 % (81 species) of the molluscan fauna are considered endemic to the broader bioregion, their known distribution ranges restricted to the temperate/tropical overlap section of the eastern Australian coast (Central Eastern Shelf Transition).
