A recent systematic review of snails in the genus Campeloma found in the Tennessee River basin has indicated that cryptic biodiversity may be present within the slender campeloma species as it is currently recognized, meaning the currently recognized species may actually represent multiple species that are superficially similar in appearance (Campbell n.d.).  Additional, genetic research specific to the slender campeloma is needed.

• The shell is medium to large typically measuring between 5 to 35 millimeters (0.2 to 1.4 inches) in length (ARC 1997).
• The slender campeloma is identified in the field by its larger size for this type of snail, ovately conic shell, and tapered pointed spire (Burch 1989, Garner 2004).
• It is distinguished from the sympatric C. decisum by the presence of fine sculpture in the form of faint striations and a relatively higher spire on the shell of the slender campeloma.

The slender campeloma is typically found burrowing in soft sediments (sand or mud) or detritus (ACR 1997). 

The slender campeloma belongs to the family Viviparidae and as with other members of this family, they give birth to live young instead of laying eggs.

Their lifespan does not appear to extend beyond 3 years of age.

While the food habits of the slender campeloma are not known, it is believed that they most likely feed on detritus.
