The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. [1] The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".
Vermetus is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells. [ 1 ] The genus Vermetus is very ancient: it occurs in the fossil record from the Jurassic to the Quaternary (age range: from 164.7 to 0.0 million years ago).
These sessile snails extrude a mucous net for feeding, which negatively affects both the coral growth and morphology, reducing their rate of survival. Trapezia rufopunctata have been observed cleaning the corals of vermetid mucus while feeding on the coral itself. They feed by first massaging the coral tissue with their legs, which produces a ...
This list of marine gastropod genera in the fossil record is an attempt to list all the genera of sea snails or marine gastropod mollusks which have been found in the fossil record. Nearly all of these are genera of shelled forms, since it is relatively rare for gastropods without a shell ( sea slugs ) to leave any recognizable traces.
This list of gastropods described in 2011, is a list of new taxa of snails and slugs of every kind that have been described (following the rules of the ICZN) during the year 2011. The list only includes taxa at the level of genus or species. For changes in taxonomy above the level of genus, see Changes in the taxonomy of gastropods since 2005.
These land snails have opercula, which helps identify them as "winkles gone ashore", in other words, snails within the clade Littorinimorpha and the informal group Architaenioglossa. Members of the snail family Pulmonata , which includes carboniferous land sails and some freshwater snails of the order Basommatophora , are protandrous ...

The pasilalinic-sympathetic compass, also referred to as the snail telegraph, was a device built to test the hypothesis that snails create a permanent telepathic link when they mate. The device was developed by French occultist Jacques-Toussaint Benoît (de l'Hérault), with the supposed assistance of an American colleague, Monsieur Biat ...
