''Helix aperta'', also known as ''Cantareus apertus'',〔For those who regard ''Cornu'' as available and who classify ''Helix aperta'' and ''Helix aspersa'' in the same genus and do not like to use ''Helix'' for them, the name should be ''Cornu apertum'', but this combination has very rarely been used.〕 and commonly known as the green garden snail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails. ==Distribution== ''Helix aperta'' is native to Europe primarily near the Mediterranean Sea, and also North Africa. Distribution of ''Helix aperta'' include: * France west of Rhone estuary〔 It is protected in France, must not be collected for commercial purposes.〔 * islands in Tyrrhenian Sea〔 * Italy, Italian peninsula to Liguria and Romagna〔 * Ionian islands * central Greece〔 * Aegean islands〔 * Cyprus (only one locality)〔 * Mediterranean north Africa〔 In Salento it is known as municeḍḍe and in Sicily as attuppateḍḍu. It has also been introduced to other areas, including Australia: * It has become established in California and Louisiana. * Western Australia - nonindegenous〔(2. Helix aperta (Born) )〕 This species is already established in the USA, and is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. Therefore it has been suggested that this species be given top national quarantine significance in the USA.〔Cowie R. H., Dillon R. T., Robinson D. G. & Smith J. W. (2009).
