Cahaba pebblesnail

The Cahaba pebblesnail, scientific name Clappia cahabensis, is a species of very small freshwater snail, aquatic gastropod mollusks in the family Lithoglyphidae.

This species is named after the Cahaba River. This species is endemic to the United States.

This species was listed as extinct in the 2006 and 2010 IUCN Red List. It was thought to be extinct because of water pollution coming from modern surface mining of coal in the USA.

Until recently the Cahaba pebblesnail was believed to be extinct, one of 34 snail species fallen victim to dams built along the Coosa River between 1917 and 1967. In 2004 however, biologists discovered the snail living less than fifty miles to the west, in Alabama's Cahaba River, which parallels the Coosa.
