Cone snails, or cones, are highly venomous sea snails of the family Conidae. [1] Fossils of cone snails have been found from the Eocene to the Holocene epochs. [2] Cone snail species have shells that are roughly conical in shape. Many species have colorful patterning on the shell surface. [3] Cone snails are almost exclusively tropical in ...
Snails can be found in a very wide range of environments, including ditches, deserts, and the abyssal depths of the sea. Although land snails may be more familiar to laymen, marine snails constitute the majority of snail species, and have much greater diversity and a greater biomass. Numerous kinds of snail can also be found in fresh water.
Liguus virgineus, also known as the candy cane snail, is a species of tree-living snail native to the Caribbean island of Hispaniola. It has a distinctive conical shell of 30–60 mm (1.2–2.4 in). It has a distinctive conical shell of 30–60 mm (1.2–2.4 in).
Cone snails of the family Conidae are a diverse group of predatory marine gastropods, mostly tropical in distribution, which hunt and immobilize prey using a modified harpoon-like radular tooth that can deliver neurotoxic conopeptides. All cone snails are venomous, though the danger posed to humans varies widely by species.
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. [4] Conotoxin-G is a toxin derived from the venom of C. geographus. Only 15-20 of the venom's 100-200 toxic peptides are used for feeding.
Cone snail venom apparatus. There are approximately 30 records of humans killed by cone snails. Human victims suffer little pain, because the venom contains an analgesic component. Some species reportedly can kill a human in under five minutes, thus the name "cigarette snail" as supposedly one only has time to smoke a cigarette before dying.
A few species of molluscs, including octopuses and cone snails, can sting or bite. Some present a serious risk to people handling them. However, deaths from jellyfish stings are ten times as common as those from mollusc bites. [43] Live cone snails can be dangerous to shell collectors, but are useful to neurology researchers. [44]

The following is a list of poisonous animals, which are animals that passively deliver toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested.
