Many species have colorful patterning on the shell surface. They are less commonly found in deeper waters. The geography cone, like other cones, attacks its prey by using an extensible tentacle, tipped with a poisonous sting. The Cone Snail is a large predatory sea snail and is also known as Conus, Cone Shells or Cones. Other Cone Snails can be equally as dangerous, especially the Textile Cone ( Conus textile ).

Conus geographus, popularly called the geography cone or the geographer cone, is a species of predatory cone snail. The fish-hunting cone snail, Conus geographus, is the deadliest snail on earth.In the absence of medical intervention, 70% of human stinging cases are fatal. The venom from one cone snail has a hypothesized potential of killing up to 700 people. Conus geographus Linnaeus, 1758. The bright colors and patterns of cone snails are attractive,[16] hence people sometimes pick up the live animals. Out of all the cone snails found, the Geography Cone Snail is known to be the most venomous of them all. effect of mangrove facilitation on the expansion of geographic distribution of certain cone snail species (Conus eburneus,C. (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.

Conantokins are antagonists to the nicotinic aceytlcholine receptors (the means by which the cone snails paralyze their prey) and N-Methyl-D-aspartic acid (NMDA) receptors, which (in humans) are involved with pain reception, drug and alcohol withdrawal symptoms, memory, and learning. see also oceanic vent. When the snail detects a prey animal nearby, it extends a long flexible tube called a proboscis towards the prey. Specialized insulin is used for chemical warfare by fish-hunting cone snails.

One species, the Geography cone, Conus geographus, is also known colloquially as the "cigarette snail," in the belief that the victim will have only enough time to smoke a cigarette before perishing. All capture their prey by means of harpoon-like hollow teeth (radula) that are rapidly jabbed into their prey to inject the toxic venom. Conus textile, the textile cone or the cloth of gold cone is a venomous species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones.. Like all species within the genus Conus, these snails are predatory and venomous.They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all. The venom contains a complex mixture of substances that includes neurotoxins, which are chemicals that block the conduction of nerve impulses. The shells of cone snails are often brightly colored and have interesting patterns, although in some species the color patterns may be partially or completely hidden under an opaque layer of periostracum. However, some species are adapted to temperate/semi tropical environments, such as the Cape coast of South Africa,[7][8] the Mediterranean,[9] or the cool subtropical waters of southern California (Californiconus californicus),[10] and are endemic to these areas. Unsurprisingly, envenomation occurs most often on the palms and fingers. The way it injects venom is something that the average diver wouldn't know. . This radically changes the range of venomous molluscan biodiversity that can be realistically investigated. Using 329 species, the authors carried out molecular phylogenetic analyses. 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. [6], Recent research has revealed that C. geographus uses a form of insulin as a means of stunning its prey. Jimenez, E. 2009. This fairly large cone is the most dangerous of the cone shell species.

It has a mottled appearance, clouded and coarsely reticulated with chestnut or chocolate, usually forming two very irregular bands. Only 15-20 of the venom's 100-200 toxic peptides are used for feeding. In addition, since NMDA receptors are involved with memory, conantokins can potentially be used in treating Alzheimer's and Parkinson's diseases, and possibly used as anti-convulsants in epilepsy or as a means of alleviating drug-induced withdrawal symptoms. Hypothetically, the venom from one cone snail has could kill up to 700 people. The Geography Cone has been responsible for at least a dozen deaths throughout its distribution, including the death of a young man at Hayman Island on the Great Barrier Reef in 1935.

(especially cone snails, which are one of the most diverse groups of marine animals), particularly in . J., 1958, Vol. Their surrounding habitat includes living or fragmented coral reefs, and sandy regions within tidal zones. This is risky, because the snail often fires its harpoon in these situations. The test for clustering of distribution areas indicated that the distribution ranges of land snails in south-eastern Africa show a clustering tendency , as the test statistic t = 0.429, the ratio between the 25% largest and smallest distances [64, 69] for our dataset, is smaller than expected by the null model (Simulated t = 0.451; ranging from .

Some of them also date back to the Holocene Epoch 12,000 to 11,500 years ago. The appeal of the cone snail's venom for creating pharmaceutical drugs is the precision and speed with which the various components act; many of the compounds target a particular class of receptor, to the exclusion of any other. The venom of cone snails contains hundreds of different compounds, and its exact composition varies widely from one species to another. The cone snail is believed to have origins in the Indo-Pacific region. The only two threats to these snails is crabs cracking their shells and the careful harvesting of their beautiful shells, this isn't without the collectors risk of being poisoned. fertilization takes place within the female's body. Species considered small-ranged are those with a geographic range size smaller than the global median (i.e., the 50% of species with the smallest ranges). They are indigenous to the reefs of the Indo-Pacific region, except for Hawaii. The animals produce a potent venom to paralyze their prey.
