Cepaea is a genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Helicidae. The shells of species within this genus are often brightly colored and patterned with stripes.[3] Species from this genus, in particular the common and widespread C. nemoralis and C. hortensis, have been model species for early studies of genetics and natural selection.[4] They occur in Europe, although introduced populations occur elsewhere in the world.[2]
Like many Helicidae, this genus of snails create and use love darts.[3]
Species
Four species are currently classified in the genus Cepaea.[2]
However, molecular phylogenetic studies suggest that the latter two should be placed in unrelated genera:[5]
- Cepaea hortensis (O. F. Müller, 1774)
- Cepaea nemoralis (Linnaeus, 1758)
- Cepaea sylvatica (Draparnaud, 1801)
- Cepaea vindobonensis (Férussac, 1821)
