|A live individual of Omphiscola glabra on a paper grid, scale bar 1 cm|
- endangered in Germany. Critically endangered in Western Germany (Rheinland-Pfalz, Saarland, Nordrhein-Westfalen, Hessen). Extinct in Bavaria.
- one site in the south east of Ireland was found in 2009, but it is listed as extinct on the local Red List (2009).
- vulnerable in Great Britain
The distribution of Omphiscola glabra is very scattered and rare. It is seriously threatened, and has become locally extinct in many places. It is threatened by continuing habitat destruction because of drainage and intensive farming. Acriculturally induced eutrophication is also a threat. Omphiscola glabra has disappeared widely from urbanized areas such as London.
The shell is strongly cylindrical, horny, often with a brownish or blackish surface, the apex is blunt, 7-8 moderately convex whorls, with last whorl being twice as high as the narrow aperture, and with aperture often with white lip.
This snail lives in places such as swampy meadows and ditches.
Omphiscola glabra is said to occur in small areas of standing water that have a lot of vegetation such as swamps, and also in standing forest waters with leaf litter, often in water with organic iron contents and low calcium contents.[clarification needed]
In Britain however, this species occurs in small standing waters that are low in nutrients, with poor aquatic flora, often in waters drying out periodically. They usually do not occur in habitats with high molluscan diversity, and usually in habitats on uncultivated land. They are calciphile and have a pH tolerance of 5.4-8.8.[clarification needed]
Omphiscola glabra can serve as an intermediate host for several digenean trematodes. In France, Omphiscola glabra was naturally infected with Fasciola hepatica, Paramphistomum daubnei, and Haplometra cylindracea. Moreover, a recent report suggests that the species is also susceptible to Fascioloides magna infection.
