Venom variation during prey capture by the cone snail, Conus textile. [PDF]

PLoS ONE, 2014
Observations of the mollusc-hunting cone snail Conus textile during feeding reveal that prey are often stung multiple times in succession. While studies on the venom peptides injected by fish-hunting cone snails have become common, these approaches have ...

Cone snail species off the Brazilian coast and their venoms: a review and update

Journal of Venomous Animals and Toxins including Tropical Diseases, 2023
The genus Conus includes over 900 species of marine invertebrates known as cone snails, whose venoms are among the most powerful described so far.

Coordinated adaptations define the ontogenetic shift from worm- to fish-hunting in a venomous cone snail

Nature Communications, 2023
Marine cone snails have attracted researchers from all disciplines but early life stages have received limited attention due to difficulties accessing or rearing juvenile specimens.

The M-Superfamily of Conotoxins: A Review [PDF]

, 2010
Throughout the world there exist both predator and prey. This distinction is apparent though sometimes misleading. Take for example marine snails of the genus Conus that are present across the oceans of the southern hemisphere [1].

A toxin-based approach to neuropeptide and peptide hormone discovery

Frontiers in Molecular Neuroscience, 2023
Peptide hormones and neuropeptides form a diverse class of bioactive secreted molecules that control essential processes in animals. Despite breakthroughs in peptide discovery, many signaling peptides remain undiscovered.

Fish-hunting cone snail venoms are a rich source of minimized ligands of the vertebrate insulin receptor

eLife, 2019
The fish-hunting marine cone snail Conus geographus uses a specialized venom insulin to induce hypoglycemic shock in its prey. We recently showed that this venom insulin, Con-Ins G1, has unique characteristics relevant to the design of new insulin ...
