Alabama lampmussel (Lampsilis virescens)
Listing Status: and
The Alabama lampmussel is a medium sized freshwater mussel usually measuring less than 75 millimeters (mm; ~3 inches (in.)) in length with a moderately thick/moderately inflated shell that is often tawny to greenish yellow, with white nacre (Williams et al. 2008).

» Life History
It historically occurred in small creeks to large rivers; however, at present, it only seems to persist in small to moderate-sized streams in areas of slow to moderate current within sand and gravel substrates. The lampmussel has also been found in areas with stands of water willow (Justicia americana) (Williams et al. 2008).
Movement / Home Range
The Alabama lampmussel historically occurred from the headwaters in eastern Tennessee downstream to Muscle Shoals in northwestern Alabama (Mirarchi 2004, Williams et al. 2008). It was known to occur in the PRR (Jackson Co., AL), Bear Creek (Colbert Co., AL), Little Bear Creek (Franklin Co., AL), a tributary to Bear Creek, Spring Creek (Colbert Co., AL), and Anderson Creek (Lauderdale Co., AL), a tributary to the Elk River (Ortmann 1918, Ortmann 1925, Isom and Yokley 1968, Isom and Yokley 1973) in northern Alabama, and the Emory River (Roane and Morgan counties, TN), and Coal Creek (Anderson Co., TN), a tributary to the Clinch River (Ortmann 1918, Ortmann 1925), in eastern Tennessee. It has been eliminated throughout a majority of its historic range, and is now restricted to only the upper reaches of the PRR system, Jackson County, Alabama, and potentially into Franklin County, Tennessee (Parmalee and Bogan 1998), and in the upper Emory River, Morgan County, Tennessee (Dinkens et al. 2012).
This species is a long-term brooder and is gravid from late summer or autumn into the following summer (Williams et al. 2008). Dr. Paul Johnson's work at the Tennessee Aquarium Research Institute and AABC have successfully transformed lampmussels on several different fish species in the family Centrarchidae, including: rock bass (Ambloplites rupestris), green sunfish (Lepomis cyanellus), bluegill sunfish (L. macrochirus), smallmouth bass (Micropterus dolomieu), spotted bass (M. punctulatus), largemouth bass (M. salmoides), and redeye bass (M. coosae) (P. Johnson unpublished data, Fobian and Johnson 2010, Johnson and Hubbs 2010). The banded sculpin (Cottus carolinae) was also reported as a potential host (P. Johnson unpublished data).
