Slovakia is a land-locked country, and therefore the molluscs of Slovakia are all land and freshwater species. There are 247^[1] species of molluscs living in the wild in Slovakia. In addition there are 9 gastropod species living only in greenhouses.^[2]

There are a total of 219^[1] species of gastropods, which breaks down to 51^[1] species of freshwater gastropods, and 168^[1] species of land gastropods, plus 28^[1] species of bivalves living in the wild.

There are 8 non-indigenous gastropod species (3 freshwater and 5 land species) and 3 species of bivalves in the wild in Slovakia. This is a total of 6 freshwater non-indigenous species of wild molluscs.

Summary table of number of species

There are 2 extinct species in Slovakia (locally extinct): Theodoxus transversalis and Esperiana esperi.^{[citation needed]}

There are endemic species of molluscs in Slovakia:

• Alzoniella slovenica in Slovakia (and in Moravia in the Czech Republic too)
• Alopia bielzii clathrata (Rossmässler, 1857)
• Deroceras fatrense

Grid distribution maps of all species were made by Lisický (1991).^[3]
