While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. -

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.

Fossil and Recent Molluscan Types in the Auckland War Memorial Museum
Fossil and Recent molluscan types in the Auckland War Memorial Museum. Part 2: Polyplacophora and Scaphopoda Wilma M. Blom Auckland War Memorial Museum Abstract The Marine Department of Auckland War Memorial Museum has nearly 1800 primary types and a further 1811 paratypes and paralectotypes types in its collections. The majority are molluscan and this second part of a catalogue of these collections reviews the types for 14 chiton and two scaphopod species. It deals with seven primary types and 12 secondary type lots, which are split between 12 Recent taxa and four fossil taxa. All of the holotypes reviewed here have been illustrated.

STEBBINS 1,* and DOUGLAS J. EERNISSE 2 1 City of San Diego Marine Biology Laboratory, Metropolitan Wastewater Department, San Diego, CA, USA 2 Department of Biological Science, California State University, Fullerton, CA, USA Abstract: About 36 species of chitons possibly occur at depths greater than 30 m along the continental shelf and slope of the Southern California Bight (SCB), although little is known about their distribution or ecology. Nineteen species are reported here based on chitons collected as part of long-term, local benthic monitoring programs or less frequent region-wide surveys of the entire SCB, and these show little overlap with species that occur at depths typically encountered by scuba divers. Most chitons were collected between 30-305 m depths, although records are included for a few from slightly shallower waters. Of the two extant chiton lineages, Lepidopleurida is represented by Leptochitonidae (2 genera, 3 species), while Chitonida is represented by Ischnochitonidae (2 genera, 6-9 species) and Mopaliidae (4 genera, 7 species). -

E-mail: [email protected] At present, over 300 species of marine alien Mollusca are reported from the European waters (Streftaris et al. 2005; Zenetos et al. 2010). However, only three alien polyplacophoran have been recorded: Chaetopleura angulata (Spengler, 1797), Acanthopleura gemmata (Blainville, 1825) and Chiton hululensis (E. A. Smith, 1903); the latter is considered as “questionable” (Zenetos et al. 2010). These polyplacophoran constituting about 1% of the alien marine mollusc reported from Europe. Here we present the first record of Tonicia atrata (Sowerby, 1840) and Chiton cumingsii Frembly, 1827 in European waters, constituting the first evidence of their presence outside their native range. Furthermore, we give brief notes on the taxonomy and distribution of T. atrata and C. cumingsii, and discuss the potential pathways for introduction to Europe. In Europe, T. atrata occurs together with the well-known alien Ch. angulata; and probably both species have historically been misidentified in collections because both reach large size (> 60 mm) and in many cases the larger size was commonly used to differentiate the presumed alien (Ch. angulata) from the native polyplacophoran of smaller size. -

Mollusca, Polyplacophora) Movement Behaviour, with Comparison Between Habitats Differing in Complexity
The first observations of Ischnochiton (Mollusca, Polyplacophora) movement behaviour, with comparison between habitats differing in complexity Kiran Liversage1 and Kirsten Benkendorff2 1 Estonian Marine Institute, University of Tartu, Tallinn, Estonia 2 Marine Ecology Research Centre, Southern Cross University, Lismore, NSW, Australia ABSTRACT Most species of Ischnochiton are habitat specialists and are almost always found underneath unstable marine hard-substrata such as boulders. The difficulty of experimenting on these chitons without causing disturbance means little is known about their ecology despite their importance as a group that often contributes greatly to coastal species diversity. In the present study we measured among-boulder distributional patterns of Ischnochiton smaragdinus, and used time-lapse photography to quantify movement behaviours within different habitat types (pebble substrata and rock-platform). In intertidal rock-pools in South Australia, I. smaragdinus were significantly overdispersed among boulders, as most boulders had few individuals but a small proportion harboured large populations. I. smaragdinus individuals emerge from underneath boulders during nocturnal low-tides and move amongst the inter-boulder matrix (pebbles or rock-platform). Seventy-two percent of chitons in the pebble matrix did not move from one pebble to another within the periods of observation (55–130 min) but a small proportion moved across as many as five pebbles per hour, indicating a capacity for adults to migrate among disconnected habitat
