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. -
Study Guide Entomology & Nematology Department
STUDY GUIDE ENTOMOLOGY & NEMATOLOGY DEPARTMENT DPM COMPREHENSIVE EXAMINATIONS The Entomology & Nematology Comprehensive Examinations consist of 3 sections: pest identification (30%), pest biology and management (40%), and core concepts and synthesis (30%). These examinations are limited to information about invertebrate animal pests, principally insects and nematodes, but also plant feeding mites and terrestrial molluscs. A. Pest identification Students will be presented with insects, mites, molluscs, and nematodes that they must identify. Some may be recognizable by sight, but others may require keys for identification. Students will be provided with identification aids (keys), where necessary, and be expected to use them to identify the subjects accurately. The unknowns will be selected from the list of important insect, mite, mollusc, and nematode pests (Table 1) though we will emphasize those with a single or double asterisk [* or **]), as these normally are the more important pests. Included in this list are some that pose a threat but are not currently found in Florida. B. Pest biology and management Students will answer 8-10 questions on insect, mite, mollusc, and nematode pest biology (sampling, distribution, life cycle, damage) and management. The animals for which students are responsible to know biology and management are listed in Table 1 (preceded by double asterisk [**]). C. Core Concepts and Synthesis Section: Students will answer 3 or 4 questions that cover core areas of Entomology/Nematology and demonstrate knowledge of core areas, but also analysis and problem solving. Suggested reference/reading material is listed in Table 2. You might want to read through these in preparation for the Comprehensive Examinations. -

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. -
Mollusca, Neogastropoda) from the Mozambique Channel and New Caledonia
Bull. Mus. natn. Hist, nat., Paris, 4e ser., 3, 1981, section A, n° 4 : 985-1009. On a collection of buccinacean and mitracean Gastropods (Mollusca, Neogastropoda) from the Mozambique Channel and New Caledonia by W. 0. CERNOHORSKY Abstract. — The present paper deals with a collection of 59 species of buccinacean and mitra- cean gastropods belonging to 4 families from moderately shallow to deep water around the Mozam- bique Channel area, north of Madagascar. A total of 27 % of the species recovered are new geogra- phical range extensions. The New Caledonian material consists of 21 species belonging to 5 fami- lies, and was dredged, with one exception, in moderately deep water. A total of 38 % of the New Caledonian species represent new geographical records, and one of these is a new species : Voluto- mitra (Waimatea) vaubani n. sp. The new name Vexillum (Costellaria) duplex is proposed for the homonymous Mitra simphcissima Schepman, 1911, and its var. glabra Schepman, 1911. Résumé. — L'auteur étudie une collection de 59 espèces appartenant à 4 familles de Gasté- ropodes Buccinacea et Mitracea dragués dans le nord du canal du Mozambique, à des profondeurs diverses. L'étude montre une extension de l'aire de répartition connue pour 27 % des espèces. Le matériel néo-calédonien comprend 21 espèces appartenant à 5 familles et a été dragué, à une exception près, en eau relativement peu profonde. L'aire de répartition connue se trouve étendue pour 38 % des espèces, dont une est nouvelle : Volulomilra (Waimatea) vaubani n. sp. Le nom nouveau Vexillum (Costellaria) duplex est proposé en remplacement du nom Mitra simplicissima Schepman, 1911, et de sa variété glabra Schepman, 1911, tous deux préoccupés. -

(UPD, Philippines) in September 2003 for the degree of Doctor of Philosophy in Marine Biology within the School of Marine Biology and Aquaculture James Cook University ABSTRACT The aim of this thesis is to describe the distribution of coral reef and shore gastropods in the Philippines, using the species rich taxa, Nerita, Clypeomorus, Muricidae, Littorinidae, Conus and Oliva. These taxa represent the major gastropod groups in the intertidal and shallow water ecosystems of the Philippines. This distribution is described with reference to the McManus (1985) basin isolation hypothesis of species diversity in Southeast Asia. I examine species-area relationships, range sizes and shapes, major ecological factors that may affect these relationships and ranges, and a phylogeny of one taxon. Range shape and orientation is largely determined by geography. Large ranges are typical of mid-intertidal herbivorous species. Triangualar shaped or narrow ranges are typical of carnivorous taxa. Narrow, overlapping distributions are more common in the central Philippines. The frequency of range sizesin the Philippines has the right skew typical of tropical high diversity systems. -
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.
