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

Limax is a genus of air-breathing land slugs in the terrestrial pulmonate gastropod mollusk family Limacidae. thumb|right|Limax cinereoniger The generic name Limax literally means "slug".

Chromodoris is a genus of very colourful sea slugs or dorid nudibranchs, marine gastropod molluscs, and the type genus of the family Chromodorididae. Within the genus Chromodoris, there are currently 101 classified species. Species within Chromodoris are commonly found in tropical and subtropical waters, living as members of reef communities and preying primarily on sponges. A molecular phylogeny of the family Chromodorididae resulted in this genus being restricted to a smaller number of species than formerly, most of which have longitudinal black lines on the mantle. Many former members of Ch
