Cepaea
Cepaea is a genus of large air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Helicidae. The shells are often brightly coloured and patterned with brown stripes. The two living species in this genus, C. nemoralis and C. hortensis, are widespread and common in Western and Central Europe. In North America, C. hortensis is native on the northeast coast, but both species have been introduced elsewhere, and they are also spreading further east in Europe. Both have been influential model species for ongoing studies of genetics and natural selection. Like many Helicidae
