Elimia gibbera, the shouldered elimia, is a species of freshwater snails in the family Pleuroceridae. This species was endemic to Alabama, the United States,[1][4] with records from the Coosa River.[3][2] It is now considered extinct,[1][2] the attributed cause is land-use change.[5] Already in 1936, Calvin Goodrich wrote that "To a large extent, the goniobasic fauna of the Coosa Biver must be spoken of in the past tense".[3]
Description
The shell in adults measures 17–20 mm (0.67–0.79 in) in length and 9–11 mm (0.35–0.43 in) in width.[3]
