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. -

Because of a change in the rules of the ICZN (3rd edition, 1985: 73-74), there has risen a disagreement about the concept of the "type series". In cases where a museum type-lot consists of more than one specimen, although the original author(s) did not indicate that more than one shell was used for the description, we will designate the single originally mentioned and/or figured specimen as the "lectotype". Never- theless a number of taxonomists will consider that "lectotype" as the holotype, and disregard the remaining shells in the lot as type material. -

In the last few years, a sharp increase in the number of descriptions of new species of West African cone snails, particularly from the Cabo Verde Archipelago, has taken place. In previous studies, we used mitogenome sequences for reconstructing robust phylogenies, which comprised in total 120 individuals representing the majority of species (69.7%) described from this biogeographical region (except Angolan endemics) and grouped into seven genera within the family Conidae. -

Accepted: July 28, 2018 Data deposition: Raw RNA seq data: SRA database: project number SRP139515 (SRR6983161-SRR6983169) Abstract The transcriptome of the venom duct of the Atlantic piscivorous cone species Chelyconus ermineus (Born, 1778) was determined. The venom repertoire of this species includes at least 378 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity. A total of three individuals were sequenced showing considerable intraspecific variation: each individual had many exclusive conotoxin precursors, and only 20% of all inferred mature peptides were common to all individuals. Three different regions (distal, medium, and proximal with respect to the venom bulb) of the venom duct were analyzed independently. Diversity (in terms of number of distinct members) of conotoxin precursor superfamilies increased toward the distal region whereas transcripts detected toward the proximal region showed higher expression levels. -

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. -

The type genus Raphitoma Bellardi, 1847 is well known in the mediterranen Seas with about 40 species, some of which are still undescribed. Morphological analyses carried out on the genus Raphitoma Bellardi, 1847 (Mollusca Neogastropoda Conoidea Raphitomidae) from Mediterranean Sea allowed to identify a new species which is described in the present paper.

(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. -
