A fatal neurotoxic poisoning case happened in Khanh Hoa province 2020 after eating a certain number of marine gastropods, later identified as Nassarius glans, one the common gastropods Vietnam. As remaining causative food incident, 62 specimens were collected to examine tetrodotoxin toxicity individual variation and frequency toxic by using HILIC/MS-MS analysis. 100% studied exhibited (556 ± 82...

We describe the construction of amplification primers designed to target a portion of the mitochondrial cytochrome b locus in a variety of molluscan taxa. Combinations of two sets of primers successfully amplified cytochrome b from several species of gastropods, bivalves, and cephalopods. Sequence analysis of these amplified products revealed nucleotide diversity in small samples within several...

Four new species of shallow-water marine gastropods belonging to the family Rissoidae are described from the Archipelago of the Azores: Setiaalexandrae sp. n., Setiaermelindoi sp. n., Setianetoae sp. n., and Manzoniamartinsi sp. n. These novelties increase the regional rissoid fauna to 39 species, of which 29 live in shallow-water habitats. A list of the species of Rissoidae from the Azores is ...

DNA barcoding is an effective and powerful tool for taxonomic identification thus very useful biodiversity monitoring. This study investigated the usefulness of mitochondrial 12S-rRNA gene shelled marine gastropods. To do so, we determined partial sequences 75 vouchered museum specimens from 69 species gastropods Japan. The have been identified morphologically, natural history data catalog. Seq...

A review describes general trends in research of conotoxins that are peptide toxins isolated from sea gastropods of the Conus genus, since the toxins were discovered in 1970th. There are disclosed a conotoxin classification, their structure diversity and different ways of action to their molecular targets, mainly, ion channels. In the applied aspect of conotoxin research, drug discovery and dev...

Four new species of buccinoid gastropods from the continental shelf and slope are described. Neptunea flatteryensis Clark, n. sp. Latisipho ritteri depths 134- 165 m off Cape Flattery area Washington State, Buccinum cascadiense found at bathyal 788-1203 m, coasts Oregon, Golikovia fitchi 722-1240 California.

Marine gastropods of the family Naticidae are worldwide distributed and known for their unusual predatory habits. Due to wide distribution, naticids studied like predators intertidal bivalves. The present study demonstrates predation naticid gastropod Natica marochiensis on bivalve Donax striatus in northeastern region Brazil.

The venom gland of predatory cone snails (Conus spp.), which secretes neurotoxic peptides that rapidly immobilize prey, is a proposed key innovation for facilitating the extraordinary feeding behaviour of these gastropod molluscs. Nevertheless, the unusual morphology of this gland has generated controversy about its evolutionary origin and possible homologues in other gastropods. I cultured fee...
