In comparison with other species, the shell has a noticeably wider and convex mid-body, with a flattened spire. When the snail detects a prey animal nearby, it extends a long flexible tube called a proboscis towards the prey. Using 329 species, the authors carried out molecular phylogenetic analyses. Research shows that certain component proteins of the venom target specific human pain receptors and can be up to 10,000 times more potent than morphine without morphine's addictive properties and side-effects. It lives in reefs of the tropical Indo-Pacific, and hunts small fish. Cone snail venom is so potent that it can immediately paralyze and eventually kill prey. Comparisons of temperature as well as cone snail abundance and diversity were conducted between marsh grasses, mangroves and sand flat habitats. They recognize 57 subgenera within Conus, and 11 subgenera within the genus Conasprella. Unsurprisingly, envenomation . This genus is placed in the subfamily Coninae within the family Conidae.

Naturally occurring, beach-worn cone shell "tops" (the broken-off spire of the shell, which usually end up with a hole worn at the tip) can function as beads without any further modification. 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). Humans are not typical cone snail prey and envenomation is most likely to occur during handling. Weight: 0.055-5.51 lb (0.025 to 25 kg) Shell: The shell is a vital part of the snail, holding most of its vital organs.

The venom contains a complex mixture of substances that includes neurotoxins, which are chemicals that block the conduction of nerve impulses. 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 . 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 . [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. Published observations on reproductive behavior were made in aquaria, and direct observations on ritual courtships or competition for a mate in the wild is lacking. there is no antidote for cone venom; the treatment consists solely of trying to keep the victim alive until the poison wears off? Although all cone snails hunt and kill prey using venom, the venom of this species is potent enough to kill humans. Symptoms of a more serious cone snail sting include intense, localized pain, swelling, numbness and tingling and vomiting. [2] Cone snail species have shells that are more or less conical in shape (hence their common name).
