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.
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 ...
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.
The largest living species is the Giant African Snail or Ghana Tiger Snail (Achatina achatina; Family Achatinidae), which can measure up to 30 cm. [13] [14] The largest land snails of non-tropical Eurasia are endemic Caucasian snails Helix buchi and Helix goderdziana from the south-eastern Black Sea area in Georgia and Turkey; diameter of the ...
Each snail lays up to 1200 eggs per year. Achatina achatina is an important source of animal protein for West African forest-dwelling ethnic groups, and there is potential for commercial farming. [8] This species' substantial size and potential for rapid population growth can make the snail a serious pest when introduced to non-native ecosystems.
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.
The flukes have a complex life cycle with freshwater snails as intermediate hosts; people swimming or washing in the water are at risk of infection. [52] Molluscs can also carry angiostrongyliasis , a disease caused by the worms of the Angiostrongylus spp., which can occur after voluntarily or inadvertently consuming raw snails, slugs, other ...
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]
