  • Thirteen New Records of Marine Invertebrates and Two of Fishes from Cape Verde Islands
    Thirteen new records of marine invertebrates and two of fishes from Cape Verde Islands PETER WIRTZ Wirtz, P. 2009. Thirteen new records of marine invertebrates and two of fishes from Cape Verde Islands. Arquipélago. Life and Marine Sciences 26: 51-56. The sea anemones Actinoporus elegans Duchassaing, 1850 and Anthothoe affinis (Johnson, 1861) are new records from Cape Verde Islands. Also new to the marine fauna of Cape Verde are an undescribed mysid species of the genus Heteromysis that lives in association with the polychaete Branchiomma nigromaculata, the shrimp Tulearicoaris neglecta Chace, 1969 that lives in association with the sea urchin Diadema antillarum, an undescribed nudibranch of the genus Hypselodoris, and two undescribed species of the parasitic gastropod genus Melanella and Melanella cf. eburnea. An undescribed plathelmint of the genus Pseudobiceros, the nudibranch Phyllidia flava (Aradas, 1847) and the parasitic gastropod Echineulima leucophaes (Tomlin & Shackleford, 1913) are recorded, based on colour photos taken in the field. The crab Nepinnotheres viridis Manning, 1993 was encountered in the bivalve Pseudochama radians, which represents the first host record for this pinnotherid species. The nudibranch Tambja anayana, previously only known from a single animal, was reencountered and photographed alive. The sea anemone Actinoporus elegans, previously only known from the western Atlantic, is also reported here from São Tomé Island. In addition, the bythiid fish Grammonus longhursti and an undescribed species of the genus Apletodon are recorded from the Cape Verde Islands for the first time.

    Graellsia, 53: 111-175 (1997) DESCRIPCIÓN DE NUEVAS ESPECIES ANIMALES DE LA PENÍNSULA IBÉRICA E ISLAS BALEARES (1978-1994): TENDENCIAS TAXONÓMICAS Y LISTADO SISTEMÁTICO M. Esteban (*) y B. Sanchiz (*) RESUMEN Durante el periodo 1978-1994 se han descrito cerca de 2.000 especies animales nue- vas para la ciencia en territorio ibérico-balear. Se presenta como apéndice un listado completo de las especies (1978-1993), ordenadas taxonómicamente, así como de sus referencias bibliográficas. Como tendencias generales en este proceso de inventario de la biodiversidad se aprecia un incremento moderado y sostenido en el número de taxones descritos, junto a una cada vez mayor contribución de los autores españoles. Es cada vez mayor el número de especies publicadas en revistas que aparecen en el Science Citation Index, así como el uso del idioma inglés. La mayoría de los phyla, clases u órdenes mues- tran gran variación en la cantidad de especies descritas cada año, dado el pequeño núme- ro absoluto de publicaciones. Los insectos son claramente el colectivo más estudiado, pero se aprecia una disminución en su importancia relativa, asociada al incremento de estudios en grupos poco conocidos como los nematodos.

  • THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
    August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject.

  • CONE SHELLS - CONIDAE MNHN Koumac 2018
    Living Seashells of the Tropical Indo-Pacific Photographic guide with 1500+ species covered Andrey Ryanskiy INTRODUCTION, COPYRIGHT, ACKNOWLEDGMENTS INTRODUCTION Seashell or sea shells are the hard exoskeleton of mollusks such as snails, clams, chitons. For most people, acquaintance with mollusks began with empty shells. These shells often delight the eye with a variety of shapes and colors. Conchology studies the mollusk shells and this science dates back to the 17th century. However, modern science - malacology is the study of mollusks as whole organisms. Today more and more people are interacting with ocean - divers, snorkelers, beach goers - all of them often find in the seas not empty shells, but live mollusks - living shells, whose appearance is significantly different from museum specimens. This book serves as a tool for identifying such animals. The book covers the region from the Red Sea to Hawaii, Marshall Islands and Guam. Inside the book: • Photographs of 1500+ species, including one hundred cowries (Cypraeidae) and more than one hundred twenty allied cowries (Ovulidae) of the region; • Live photo of hundreds of species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and index at the end of the book ACKNOWLEDGMENTS The significant part of photographs in this book were made by Jeanette Johnson and Scott Johnson during the decades of diving and exploring the beautiful reefs of Indo-Pacific from Indonesia and Philippines to Hawaii and Solomons. They provided to readers not only the great photos but also in-depth knowledge of the fascinating world of living seashells. Sincere thanks to Philippe Bouchet, National Museum of Natural History (Paris), for inviting the author to participate in the La Planete Revisitee expedition program and permission to use some of the NMNH photos.

VERMEIJ A B The limpet form in gastropods: evolution, distribution, and implications for the comparative study of history GEERAT J. VERMEIJ* Department of Earth and Planetary Science, University of California, Davis, Davis, CA,USA C D Received 19 April 2015; revised 30 June 2016; accepted for publication 30 June 2016 The limpet form – a cap-shaped or slipper-shaped univalved shell – convergently evolved in many gastropod lineages, but questions remain about when, how often, and under which circumstances it originated. Except for some predation-resistant limpets in shallow-water marine environments, limpets are not well adapted to intense competition and predation, leading to the prediction that they originated in refugial habitats where exposure to predators and competitors is low. A survey of fossil and living limpets indicates that the limpet form evolved independently in at least 54 lineages, with particularly frequent origins in early-diverging gastropod clades, as well as in Neritimorpha and Heterobranchia. There are at least 14 origins in freshwater and 10 in the deep sea, E F with known times ranging from the Cambrian to the Neogene.

Adams, 1863) is redescribed based on newly obtained material from Japan. The diagnosis of the genus is also revised. Hemiliostraca capreolus n. sp. was previously misidentied as H. samoensis in museum collections and in literature. This new species was collected from Okinawa-jima Island and Amami-Oshima Island, southern Japan, and can be distinguished from H. samoensis by its distinct color patterns and markings. A recently collected specimen from an unidentied species of ophiuroid from Wakayama Prefecture, central Japan, is herein conrmed to be identiable with H. conspurcata, which has not been recorded since its originally description from central Japan in 1863. Hemiliostraca tenuis n. sp. was collected from an unidentied species of sponge and the ophiuroid Ophiarachnella septemspinosa from Kume-jima Island, southern Japan.
