The species may on occasion be of use as an indicator of environmental pollution, because it deposits heavy metals, such as lead in its shell. [11] Until this was established, Italian research teams and others used the generic name Cantareus instead. Cryptomphalus aspersus), known by the common name garden snail, is a species of land snail.It is a terrestrial pulmonate gastropod mollusc in the family Helicidae, which includes some of the most familiar land snails.Of all terrestrial molluscs, this species may well be the most widely known.

However, in a number of publications since 1990,[5] it has instead been placed in various genera previously considered as subgenera of Helix. Of all terrestrial molluscs, this species may well be the most widely known. 133. The mouth is located beneath the tentacles, and contains a chitinous radula with which the snail scrapes and manipulates food particles. [4] The snail also has an osmoregulatory mechanism that prevents excessive absorption of water during hibernation. It also is an omnivorous scavenger that feeds on rotting plant material and on occasion will scavenge animal matter, such as crushed snails and worms. It has no operculum; during dry or cold weather it seals the aperture of the shell with a thin membrane of dried mucus; the term for such a membrane is epiphragm. Müller, 1774 Helix aspersa var. From Crete are known a dish called "chochloi mpoumpouristoi"(snails turned upside down), the snails cooked alive in a hot pan, on a thick layer of sea salt.

This method requires that the trap be checked every day and dead snails removed and the trap refilled with beer as it evaporates over time. [6][7] Then the name would be Cornu aspersum. However, this is not without problems, as the decollate snail is just as likely to attack and devour other species of gastropods that may represent a valuable part of the native fauna of the region. Traps should be spaced every three to four meters from one another for coverage of a large garden.[50][51][52]. 2003-2020.,,,,,, Tour de France de la biodiversité en vidéos, Fauna Europaea, scientific names and distribution of all living multicellular European land and fresh-water animals, WoRMS Editorial Board (%Y).

The Terrestrial Gastropods in Palestine. The contracted muscle relaxes while its immediately anteriad transverse band of longitudinal fibres contract in their turn, repeating the process, which continues forward until it reaches the head. [citation needed], Garden snails can be easily controlled and trapped with a simple trap created by cutting a plastic bottle in half and burying the bottom half so the top is level with the soil, then partially filling the bottle bottom with any variety of beer. [30] The size of the egg is 4 mm.[31]. [3] During aestivation, the mantle collar has the ability to change its permeability to water. About two weeks after fertilisation, the snail lays a batch of about 80 spherical pearly-white eggs into crevices in the topsoil, or sheltered under stones or the like. When overwintering, Cornu aspersum avoids the formation of ice in its tissues by altering the osmotic components of its blood (or haemolymph); this permits it to survive temperatures as low as −5 °C (23 °F). - pp. 71 mailles Lambert93 10 km.

The decollate snail (Rumina decollata) will capture and eat garden snails, and because of this it has sometimes been introduced as a biological pest control agent. In the recent scientific literature the name has been applied both to large Algerian snails[23] and to a large form found in snail farms. When injured or badly irritated the snail produces a defensive froth of mucus that might repel some enemies or overwhelm aggressive small ants and the like.
