Lyons Florida Department of Natural Resources Bureau of Marine Research St. Petersburg, FL 33701 ABSTRACT Chaetopleura staphylophera n. sp., from off North Carolina, the Bahamas, and both Florida coasts, differs from other western Atlantic Chaetopleura by posses­ sion of considerably larger, nonaligned pustules on end valves and lateral areas of intermediate valves, and from the west American C. gem m a in that pustules of that species are aligned, in radial rows. Relegation of Calloplax Thiele, 1909, to synonymy with Chaetopleura Shuttlcworth, 1853, is recommended. Investigations of continental shelf fauna of Morehead City; and the Florida Department of relatively deep waters off Florida and adjacent Natural Resources Bureau of Marine Research areas have revealed a previously unknown (FDNR; museum prefix FSBC I), St. Peters­ species of the genus Chaetopleura, Shuttleworth, burg.

    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.

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).

The goal of this study was to compare the chiton community structure of the rocky shore of Montepío during the dry and ‘nortes’ (stormy) weather periods, and to gather data on the relative growth of the dominant species. Sampling was carried out along a transect of 100 x 2 m in the intertidal zone and 83 individuals were collected. Six species were identified: Lepidochitona rosea, Chaetopleura apiculata, Ischnochiton kaasi, Lepidochitona pseudoliozonis, Lepidochitona liozonis and Acanthochitona andersoni. Species richness (S= 4) and Shannon diversity (1.36 and 1.29 bits ind-1 in dry and stormy seasons) were very similar between the 2 seasons; however, only 2 species occurred in both periods, suggesting a strong seasonal exchange of species (50%).

  • Invertebrate ID Guide
    11/13/13 1 This book is a compilation of identification resources for invertebrates found in stomach samples. By no means is it a complete list of all possible prey types. It is simply what has been found in past ChesMMAP and NEAMAP diet studies. A copy of this document is stored in both the ChesMMAP and NEAMAP lab network drives in a folder called ID Guides, along with other useful identification keys, articles, documents, and photos. If you want to see a larger version of any of the images in this document you can simply open the file and zoom in on the picture, or you can open the original file for the photo by navigating to the appropriate subfolder within the Fisheries Gut Lab folder.

ZooKeys 963: 1–36. https://doi.org/10.3897/zookeys.963.52234 Abstract An increase in richness of benthic marine mollusks towards high latitudes has been described on the Pacific coast of Chile in recent decades. This considerable increase in diversity occurs specifically at the beginning of the Magellanic Biogeographic Province. Within this province lies the Strait of Magellan, considered the most important channel because it connects the South Pacific and Atlantic Oceans. These characteristics make it an interesting area for marine research; thus, the Strait of Magellan has histori- cally been the area with the greatest research effort within the province.
