The Tumbling Creek cavesnail (Antrobia culveri) is a species of freshwater cave snail with gills and an operculum, an aquatic gastropod mollusk in the family Amnicolidae.

The common name refers to Tumbling Creek Cave, a National Natural Landmark, in Taney County, Missouri, USA.

[2][5] Hershler and Hubricht (1988)[citation needed] examined specimens of Antrobia culveri and confirmed the taxonomic placement of this species at that time in the subfamily Littoridininae.

In addition it is an aquatic troglobite, and animals who live in this specialized kind of habitat are known as stygobites or stygofauna.

[5] The number of cave snails has significantly decreased over the past few decades, from an estimated 15,118 in 1973,[5][6] to the point where only one individual was found within the survey areas during January 11, 2001[7] and April 22, 2003.
