Peptide Neurotoxins from Fish-Hunting Cone Snails

Science, 1985
To paralyze their more agile prey, the venomous fish-hunting cone snails ( Conus ) have developed a potent biochemical strategy. They produce several classes of toxic peptides (conotoxins) that attack a series of successive physiological targets in the neuromuscular system of the fish.

Cone snails lure prey with faux pheromones

C&EN Global Enterprise, 2021
Cone snails use venom when hunting their prey. While much is known about the peptides in cone snail venom , the small molecules it contains have until now not been well characterized—especially in ...

Ichthyotoxicity caused by marine cone snail venoms?

Toxicon, 2005
Ten venoms from marine cone snails were tested for ichthyotoxic effects on zebra fish (Brachydanio rerio) when added to the water. Only two venoms, from Conus capitaneus and Conus episcopatus, produced lethal effects at high concentrations (50-300 microg/ml) within 20-90 min. No sedative or hypnotic symptoms were observed.

Venomous cone snails: molecular phylogeny and the generation of toxin diversity

Toxicon, 2001
In order to investigate the generation of conotoxin diversity, delta-conotoxin sequences from nine Conus species were analyzed in the context of their phylogeny. Using a standard molecular marker, mitochondrial 16S RNA, we determined that the delta-conotoxins were derived from three distinct species clades based on the phylogenetic reconstruction of a ...

Intraspecific variation in the venom of the vermivorous cone snail Conus vexillum

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2011
A combination of proteomic and biochemical assays was used to examine variations in the venom of Conus vexillum taken from two locations (Hurgada and Sharm El-Shaikh) in the Red Sea, Egypt. Using MALDI/TOF-MS, a remarkable degree of intra-species variation between venom samples from both locations was identified.

Piscivorous Behavior of a Temperate Cone Snail,Conus californicus

The Biological Bulletin, 2005
Most of the more than 500 species of predatory marine snails in the genus Conus are tropical or semitropical, and nearly all are thought to be highly selective regarding type of prey. Conus californicus Hinds, 1844, is unusual in that it is endemic to the North American Pacific coast and preys on a large variety of benthic organisms, primarily worms ...
