Rhodacmea filosa

Rhodacmea filosa, the wicker ancylid, is a species of small, air-breathing, freshwater snail or limpet, a pulmonate gastropod in the family Planorbidae.

[3] The type locality is the Black Warrior River, south of Blount Springs, Alabama.

[3] Its survival in Choccolocco Creek is somewhat surprising, given the serious episodes of industrial pollution experienced by this watershed.

[3] Rhodacmea filosa was originally discovered and described (under the name Ancylus filosus) by Timothy Abbott Conrad in 1834.

Shell regularly oval, rather elevated; with numerous radiating prominent lines; apex very prominent, inclined, eroded, not nearly central.Rhodacmea filosa has an elevated patelliform shell with ribbing in the form of strong radiating lines running from the apex to the aperture.
