It is so common in some of small Pacific islands, especially in the Philippines, that it is routinely sold in the market as food. The magician’s cone attacks its fish prey by sticking out its light yellowish proboscis, from which venom is pushed through a harpoon-like tooth. It hunts by the hook-and-line method and so will engulf its prey after it has been paralyzed. To learn more about hook-and-line hunters, click here. Scientists have analyzed the venom of the magician’s cone and one of its venom components was discovered to have a unique pharmacological activity by blocking a specific calcium channel (N-type). After this venom component was isolated and characterized in a laboratory, researchers realized that it had potential medical application. By blocking N-type calcium channels, the venom blocks channels that when open convey pain from nerve cells. If this is blocked, the brain cannot perceive these pain signals. It was developed as a pain management drug, and is now chemically synthesized and sold under the trade name Prialt. This drug is given to patients who have very severe pain that is not alliviated by morphine. -

Miocene Continental Gastropods from the Southern Margin of the Swabian Alb (Baden-Württemberg, SW Germany)
N. Jb. Geol. Paläont. Abh. 287/1 (2018), 17–44 Article E Stuttgart, January 2018 Miocene continental gastropods from the southern margin of the Swabian Alb (Baden-Württemberg, SW Germany) Olaf Höltke, Rodrigo B. Salvador, and Michael W. Rasser With 6 figures Abstract: The Middle Miocene silvana-beds outcropping at the southern margin of the Swabian Alb bear a wide array of terrestrial and freshwater gastropods. Especially in the surroundings of the Emerberg and Tautschbuch hills, there are records of several collection sites. In the present work, we investigated material from the historical localities from these two regions, housed in museum collec- tions, in order to provide an updated check list, synthesizing the knowledge of the region in the hopes to spur renewed interest. In total, we report 14 freshwater and 50 land snail species from the area, but not all species reported in the literature could be confirmed.

Molluscan (Gastropoda and Bivalvia) Diversity and Abundance in Rocky Intertidal Areas of Lugait, Misamis Oriental, Northern Mindanao, Philippines

Abstract Composition, diversity and abundance of rocky intertidal mollusks and their relationship with the environmental parameters, viz. water quality, total organic matter and calcium carbonate were determined. A total of 43 species were identified, of which 41 species belong to Class Gastropoda under 18 families and 2 species were categorized under Class Bivalvia from 2 families. Using several diversity indices, results revealed high diversity and equitability values in the 2 sampling sites. Moreover, comparison of the mollusks abundance between the 2 sampling stations showed station 2 to be dominantly abundant with Cerithium stercusmuscarum comprising almost one-third of the total population. Canonical Correspondence Analysis showed that total organic matter and calcium carbonate in the sediment may have influenced the abundance of mollusk assemblage in station 2. The results obtained from the study are vital in order to strongly support the need to continue monitoring the Lugait marine sanctuary and its nearby surroundings. -

El intermareal rocoso de Veracruz, México, es un ecosistema que resguarda una gran biodiversidad. Sin embargo, no se ha reconocido su relevancia como con otros ecosistemas marinos. El objetivo de este estudio fue elaborar las primeras listas florística y faunística del intermareal rocoso de El Pulpo, localizada en el municipio de Cazones, Veracruz. Para ello, desde el 2013 a 2016 se efectuaron muestreos en la franja intermareal rocosa en periodos de marea baja para el registro de la biota marina y la recolecta de material biológico para su identificación taxonómica. Además, se realizó una revisión bibliográfica para complementar las listas de especies. Se registraron 51 especies de macroalgas bentónicas, una especie de fanerógama, 186 especies de invertebrados, y cinco especies de vertebrados para un total de 243 especies marinas. Las Rhodophyta son la ficoflora más representada con 29 es- pecies, mientras que el Phylum Mollusca lo es para la fauna con 139 especies. La mayoría de las especies marinas se registraron en el intermareal medio e inferior; por consiguiente la menor riqueza se registró en el intermareal superior y la constituyen algas filamentosas y foliosas, así como moluscos y crustáceos con hábitos ramoneadores y filtradores. -

Associate Editor: Nicolas Vidal Downloaded from https://academic.oup.com/mbe/article-abstract/35/11/2654/5067732 by guest on 20 November 2018 Abstract Cytolytic pore-forming proteins are widespread in living organisms, being mostly involved in both sides of the host– pathogen interaction, either contributing to the innate defense or promoting infection. In venomous organisms, such as spiders, insects, scorpions, and sea anemones, pore-forming proteins are often secreted as key components of the venom. Coluporins are pore-forming proteins recently discovered in the Mediterranean hematophagous snail Cumia reticulata (Colubrariidae), highly expressed in the salivary glands that discharge their secretion at close contact with the host. To understand their putative functional role, we investigated coluporins’ molecular diversity and evolu- tionary patterns. Coluporins is a well-diversified family including at least 30 proteins, with an overall low sequence similarity but sharing a remarkably conserved actinoporin-like predicted structure. Tracking the evolutionary history of the molluscan porin genes revealed a scattered distribution of this family, which is present in some other lineages of predatory gastropods, including venomous conoidean snails. -

ABSTRACT Title of Dissertation: PATTERNS IN
ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range. -
