Marstonia ogmorhaphe (syn. Pyrgulopsis ogmorhaphe, sometimes spelled ogmoraphe) is a rare species of freshwater snail known by the common names royal marstonia and royal springsnail. It is endemic to Tennessee in the United States, where it occurs in two streams in Marion County.[2] It is a federally listed endangered species of the United States.
This gastropod, a member of the family Hydrobiidae, the mud snails, was first described in 1977. It is under 5 millimeters long. It lives in the diatomaceous ooze and debris in springs. It is limited to the Sequatchie River Valley, where it lives in Blue Spring, the water supply for the town of Jasper, Tennessee, and the stream just past the spring. It also lives in Owen Spring, four miles away.[3]
This species is threatened by the degradation of water quality in its habitat, which is caused by coal mining and other processes.[4]
