The mitochondrial genome of the venomous cone snail Conus consors. [PDF]
PLoS ONE, 2012 Cone snails are venomous predatory marine neogastropods that belong to the species-rich superfamily of the Conoidea. So far, the mitochondrial genomes of two cone snail species (Conus textile and Conus borgesi) have been described, and these feed on ...

Prey Shifts Drive Venom Evolution in Cone Snails. [PDF]
Mol Biol EvolVenom systems are complex traits that have independently emerged multiple times in diverse plant and animal phyla. Within each venomous lineage there typically exists interspecific variation in venom composition where several factors have been proposed ...

Hormone-like peptides in the venoms of marine cone snails. [PDF]
Gen Comp Endocrinol, 2017 The venoms of cone snails (genus Conus) are remarkably complex, consisting of hundreds of typically short, disulfide-rich peptides termed conotoxins.

Specialized insulin is used for chemical warfare by fish-hunting cone snails [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2015 More than 100 species of venomous cone snails (genus Conus) are highly effective predators of fish. The vast majority of venom components identified and functionally characterized to date are neurotoxins specifically targeted to receptors, ion channels ...

Molecular phylogeny and evolution of the cone snails (Gastropoda, Conoidea) [PDF]
Molecular Phylogenetics and Evolution, 2014 We present a large-scale molecular phylogeny that includes 320 of the 761 recognized valid species of the cone snails (Conus), one of the most diverse groups of marine molluscs, based on three mitochondrial genes (COI, 16S rDNA and 12S rDNA). This is the first phylogeny of the taxon to employ concatenated sequences of several genes, and it includes ...

Structural and Functional Analyses of Cone Snail Toxins [PDF]
Marine Drugs, 2019 Cone snails are marine gastropod mollusks with one of the most powerful venoms in nature. The toxins, named conotoxins, must act quickly on the cone snails´ prey due to the fact that snails are extremely slow, reducing their hunting capability ...

Evolution of separate predation- and defence-evoked venoms in carnivorous cone snails [PDF]
Nature Communications, 2014 Venomous animals are thought to inject the same combination of toxins for both predation and defence, presumably exploiting conserved target pharmacology across prey and predators.

Dietary breadth is positively correlated with venom complexity in cone snails. [PDF]
BMC Genomics, 2016 Although diet is believed to be a major factor underlying the evolution of venom, few comparative studies examine both venom composition and diet across a radiation of venomous species.

Pharmacology of predatory and defensive venom peptides in cone snails
Molecular BioSystems, 2017 Cone snails are predatory gastropods whose neurotoxic venom peptides (conotoxins) have been extensively studied for pharmacological probes, venom evolution mechanisms and potential therapeutics.

Venomous Secretions from Marine Snails of the Terebridae Family Target Acetylcholine Receptors [PDF]
Toxins, 2013 Venoms from cone snails (Conidae) have been extensively studied during the last decades, but those from other members of the suborder Toxoglossa, such as of Terebridae and Turridae superfamilies attracted less interest so far. Here, we report the effects
