Helix aspersa - Petit-gris snails are usually only about one-third the size of a Burgundy snail with fuller, almost nutty taste that is quite distinct. The difference in size naturally also means a difference in texture. They have a different feel in the mouth, a different "chew." The shell of a mature adult has four to five whorls and measures 30 to 45mm across. It is native to the shores of the Mediterranean and up the coast of Spain and France. It is found on many British Isles, where the Romans introduced it in the first century A.D. (Some references say it dates to the Early Bronze Age.) In the early 1800's the French brought it into California where it has become a serious pest. These snails are now common throughout the U.S. It was introduced into several Eastern and Gulf states even before 1850 and, later introduced into other countries such as South Africa, New Zealand, Mexico, and Argentina. H. aspersa has a life span of 2 to 5 years. This species is more adaptable to different climates and conditions than many snails, and is found in woods, fields, sand dunes, and gardens.
