The Cone Collector N°23
THE CONE COLLECTOR #23 October 2013 THE Note from CONE the Editor COLLECTOR Dear friends, Editor The Cone scene is moving fast, with new papers being pub- António Monteiro lished on a regular basis, many of them containing descrip- tions of new species or studies of complex groups of species that Layout have baffled us for many years. A couple of books are also in André Poremski the making and they should prove of great interest to anyone Contributors interested in Cones. David P. Berschauer Pierre Escoubas Our bulletin aims at keeping everybody informed of the latest William J. Fenzan developments in the area, keeping a record of newly published R. Michael Filmer taxa and presenting our readers a wide range of articles with Michel Jolivet much and often exciting information. As always, I thank our Bernardino Monteiro many friends who contribute with texts, photos, information, Leo G.

Allan Vargas Jordy Wendriks The 3rd International Cone Meeting is also on the move. Do Alessandro Zanzi remember to mark it in your diaries for September 2014 (defi- nite date still to be announced) and to plan your trip to Ma- drid. This new event will undoubtedly be a huge success, just like the two former meetings in Stuttgart and La Rochelle. You will enjoy it and of course your presence is indispensable! For now, enjoy the new issue of TCC and be sure to let us have your opinions, views, comments, criticism… and even praise, if you feel so inclined. -
22 April 2013 the Note from CONE the Editor COLLECTOR Dear Friends
THE CONE COLLECTOR #22 April 2013 THE Note from CONE the Editor COLLECTOR Dear friends, Editor The project “The Cone Collector” is still under seven years old António Monteiro and yet when I look at all we have achieved so far I cannot help thinking that we have probably exceeded expectations. Layout André Poremski We started modestly – as becomes any serious project – back in Contributors October 2006, with our newsletter aimed at all those who are Carlos Afonso interested in studying or collecting Cones, from professional Jim Cootes biologists to amateur collectors. Today we can proudly display Remy Devorsine a total of twenty-four numbers of TCC, two hugely successful Sébastien Dutertre international meetings and a website that brings together an Günther Herndl unparalleled wealth of information on Cones. Joaquin M. Inchaustegui Bruce Livett As a matter of fact, after the uploading in our website (at www. Philippe Quiquandon Christopher Roux theconecollector.com ) of the important and vastly updated Manuel Jiménez Tenorio and augmented work by Mike Filmer’s involving taxonomy and Will van Damme nomenclature, we now have at the same address Paul Kersten’s Alessandro Zanzi extremely useful and well-known Checklist, enriched with new images and much more detailed information than before. This is the work of a team – the names of Manuel Jimenez Tenorio, Bill Fenzan, John Tucker, Gavin Malcolm, Mike Filmer, Paul Kersten and André Poremski readily come to my mind as front row collaborators of TCC, but all others who have contributed with articles, photos, opinions, suggestions and unfailing support deserve equal credit! The project belongs to all and can only survive with the continued support of all. -

Sespene 1 and Aldren J. Jamasali 2 1Department of Biological Sciences,College of Science and Mathematics, MSU-Iligan Institute of Technology, Iligan City 2Mindanao State University- Jolo, SULU Available online at: www.isca.in Received 17th April 2013, revised 26 th April 2013, accepted 4th May 2013 Abstract The Philippines is a haven of a rich diversity of marine organisms. Unraveling this diversity had posed a tremendous challenge. The existing security threat in some areas of the archipelago had led to a dearth of information with regard to the diversity of organisms especially the islands located in the province of Sulu. Marine mollusc studies are still among those that are overseen by many researchers. To date, there is still a lack of basic information such as diversity and species checklist that make it impossible to assess the rate of population lost among existing marine molluscs. There is no published information on the actual number of marine shelled molluscan species in the area. This work assessed, described and identified some economically important molluscs in the island of Hadji Panglima Tahil, in the province of Sulu, Philippines. There were a total of 18 molluscs (marine bivalves & gastropods) species found and identified in the island. The molluscs served as food, ornaments and as source of livelihood by residents in the area, which is separated by sea from Jolo, the capital municipality of the province. -

Species Biological Report Neosho Mucket (Lampsilis Rafinesqueana)
Species Biological Report Neosho Mucket (Lampsilis rafinesqueana) Cover photo: Dr. Chris Barnhart (Missouri State University) Prepared by: The Neosho Mucket Recovery Team This species biological report informs the Draft Recovery Plan for the Neosho Mucket (Lampsilis rafinesqueana) (U.S. Fish and Wildlife Service 2017). The Species Biological Report is a comprehensive biological status review by the U.S. Fish and Wildlife Service (Service) for the Neosho Mucket and provides an account of species overall viability. A Recovery Implementation Strategy, which provides the expanded narrative for the recovery activities and the implementation schedule, is available at https://www.fws.gov/arkansas-es/. The Recovery Implementation Strategy and Species Biological Report are finalized separately from the Recovery Plan and will be updated on a routine basis. Executive Summary The Neosho Mucket is a freshwater mussel endemic to the Illinois, Neosho, and Verdigris River basins in Arkansas, Kansas, Missouri, and Oklahoma. It is associated with shallow riffles and runs comprising gravel substrate and moderate to swift currents, but prefers near-shore areas or areas out of the main current in Shoal Creek and Illinois River. It does not occur in reservoirs lacking riverine characteristics. The life-history traits and habitat requirements of the Neosho Mucket make it extremely susceptible to environmental change (e.g., droughts, sedimentation, chemical contaminants). Mechanisms leading to the decline of Neosho Mucket range from local (e.g., riparian clearing, chemical contaminants, etc.), to regional influences (e.g., altered flow regimes, channelization, etc.), to global climate change. The synergistic (interaction of two or more components) effects of threats are often complex in aquatic environments, making it difficult to predict changes in mussel and fish host(s) distribution, abundance, and habitat availability that may result from these effects. -

Cone Shell, (Conus Marmoreus) Rembrandt Van Rijn 1650, Etching, Engraving and Drypoint
CONE SHELLS Cone Shell, (Conus marmoreus) Rembrandt van Rijn 1650, Etching, engraving and drypoint. Rijksmuseum, Amsterdam, Holland. Introduction ● Cone shell animals are a group of carnivorous marine gastropods. ● Worldwide there are about 300 species. There are about 80 species within Australian coastal waters. ● These animals can cause potentially lethal envenomation. ● They are prized by shell collectors the world over because of their intricate patterning and beauty, (see appendix 1 below). Description Their scientific taxonomy is: Kingdom: Animalia Phylum: Mollusca. Class: Gastropoda. Subclass: Orthogastropoda. Superorder: Caenogastropoda. Order: Sorbeoconcha. Suborder: Hypsogastropoda. Infraorder: Neogastropoda. Superfamily: Conoidea. Family: Conidae Conus textile (photo by Bruce Livett, University of Melbourne) Habitat ● The cone shell gastropods are nocturnal feeders, rarely being seen during daylight hours. ● During the day they generally lie buried beneath the sand. ● Australian species inhabit warm tropical and subtropical coastal waters. ● They are shallow water dwellers mainly inhabiting tidal reefs. ● They are especially seen around the Great Barrier Reef. ● Colder southern waters have smaller worm eating species which are not dangerous. Classification The cone shell species as a group are readily recognized by their conic shape. They may be classified according to their prey and size. The larger species prey on fish, while the intermediate sized species prey on molluscs and the smaller species on worms. The large species may grow up to 25 cm in length. 1. Piscivorous: Fish eaters, including: ● Conus striatus ● Conus geographus ● Conus magnus ● Conus catus ● Conus tulipa 2. Molluscivorous: Mollusk eaters, including: ● Conus textile ● Conus marmoreus ● Conus pennaceus 3. Vermivorous: Worm eaters. ● There are many including: C.imperialis/ C.eburneus / C.quercinus / C.lividus / C.tessulatus / C.ventricosus / C.parvatus / C.rattus / C.flavidus / C.generalis / C.arenatus Venom All species are venomous to varying degrees.
