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 ...
Deadliest animals as of 2016 [1] This is a list of the deadliest animals to humans worldwide, measured by the number of humans killed per year. Different lists have varying criteria and definitions, so lists from different sources disagree and can be contentious. This article contains a compilation of lists from several reliable sources.
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.
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.
Freshwater snails are widely known to be hosts in the lifecycles of a variety of human and animal parasites, particularly trematodes (or "flukes"). Some of these relations for prosobranch snails include Oncomelania in the family Pomatiopsidae as hosts of Schistosoma, and Bithynia, Parafossarulus and Amnicola as hosts of Opisthorchis. [14]
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.
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.
Molluscicides (/ m ə ˈ l ʌ s k ɪ ˌ s aɪ d s,-ˈ l ʌ s-/) [1] [2] – also known as snail baits, snail pellets, or slug pellets – are pesticides against molluscs, which are usually used in agriculture or gardening, in order to control gastropod pests specifically slugs and snails which damage crops or other valued plants by feeding on them.
