Helix is a genus of large, air-breathing land snails native to Europe and the Mediterranean region. They are the type genus of the family Helicidae and among the first animal genera described by Carl Linnaeus. Members of the genus first appeared during the Oligocene. Like most land snails, Helix species are hermaphroditic, and like other helicids a courting pair will impale each other with hormone-rich love darts prior to exchanging sperm. Well-known species include Helix pomatia and Helix lucorum. Cornu aspersum – another well-known helicid – was originally described as a member of Helix, but the prevailing classification places it as the sole member of the sister genus Cornu.
