Paludina naticoides C. Pfeiffer, 1828 Lithoglyphus naticoides , the gravel snail, is a species of small or minute freshwater snail with an operculum, an aquatic gastropod mollusk in the family Lithoglyphidae.

[1] Its distribution subsequently shrank to the Ponto-Azov area during cooler eras.

[5] The native distribution includes only Black Sea rivers and the Danube up to Regensburg, from southeastern to central Europe.

[6] This snail is found in the following countries: Western Europe: Central Europe: Eastern Europe: Asia: North America: This species is called "naticoides" because in shape and general appearance the shell and the operculum of this species is reminiscent of the shell and the operculum of the marine moon snails or Naticidae (for example, the Northern moon snail).

The shell is globular, light grey to greenish yellow or dark.

[1] In rivers, it lives at sites with low water currents, on solid muddy soils and at stones.
