(Chadwick, 2011; Cruz, et al., 1978; Johnson and Stablum, 1971), Conantokins ("sleeper peptides") from the geographic cone snail are a complex mix of short-chain peptides that affect a number of neural receptors in fish and mammals. cones have a poisonous stinger located on the tip of a long, extensible tentacle, which can reach up to three-quarters of the length of the shell? The geographic cone is also known by the name Anbonia, a name derived from its discovery in the Gulf of Anbonia in Indonesia. Geography Cones live on sand and rubble, under rocks and coral in the intertidal and subtidal zones. rosea G. B. Sowerby I, 1833 is a synonym of Conus eldredi Morrison, 1955. Using 329 species, the authors carried out molecular phylogenetic analyses. Philippine Science Letters, 2 (1): 60-65. (Cruz, et al., 1978; Johnson and Stablum, 1971), Observations show that snails hunt with two methods used by other Conus species: the hook-and-line method and the net-hunting method. Their surrounding habitat includes living or fragmented coral reefs, and sandy regions within tidal zones. Sizable populations were then located, and this brought the price down dramatically as shells were harvested.[31]. For humans, it's sting can result in respiratory paralysis and even death, all within a single hour. Accessed 1964.

Although all cone snails hunt and kill prey using venom, the venom of this species is known to be especially potent. Ironically, among the compounds found in cone snail venom are proteins which, when isolated, have enormous potential as pain-killing drugs. [33][36][37][38][39][40][41][42][43][44], In 2015, in the Journal of Molluscan Studies, Puillandre, Duda, Meyer, Olivera & Bouchet presented a new classification for the old genus Conus.

Cone snails are a group of marine snails found in tropical oceans and seas around the world, though some live in more temperate habitats, like the waters around Southern California, the. This poison mixture has been referred to as nirvana cabal. The geography cone is the most venomous of the 500 known cone snail species, and its venom contains hundreds of different conotoxins that regulate glutamate, adrenergic, serotonin, and cholinergic . Specimens should be handled with extreme caution. (Cruz, et al., 1978). The Nautilus, 92 (4): 150-153. They hide under coral shelves, in the sand, or under piles of debris. the geography cone is a predator, even capable of catching fish large than itself?

The geography cone, like other cones, attacks its prey by using an extensible tentacle, tipped with a poisonous sting. Therefore, smaller doses can be used, and Con-G does not seem to be addictive or to have side effects in the therapeutic dose range, unlike morphine. [4][6][7] The venom of Geography Cone Snail is a complex mix of hundreds of different toxins that is delivered through toxoglossan radula, a harpoon-like tooth propelled from an extendable proboscis. There are multiple known conotoxin peptides which code for specific receptors such as: Contulakin-G, -MrIA, -Vc1.1, Conantokin-G, -PVIIA, and O-MrVIB. having the capacity to move from one place to another. there are around 400 species of cones, found primarily in tropical oceans. Miranda Hall (author), San Diego Mesa College, Paul Detwiler (editor), San Diego Mesa College, Renee Mulcrone (editor), Special Projects. It lives in reefs of the tropical IndoPacific, and hunts small fish. Ironically, the venom has recently been discovered to contain a type of insulin, previously unseen, that can also be used as a highly effective painkiller, several thousand times more powerful than morphine without any of the addictive side effects that normal morphine gives. (Cruz, et al., 1978; Johnson and Stablum, 1971), There is no recorded data of any home range information. young are relatively well-developed when born.

The importance of the genus Conus rises from its species abundance, which is an evidence of morphological diversity, and in the production of powerful peptides ( Rckel et al., 1995 ). This classification was based on shell morphology, radular differences, anatomy, physiology, and cladistics, with comparisons to molecular (DNA) studies. [3] C. geographus has the most toxic sting known among Conus species and there are reports for about three dozen human fatalities in 300 years.
