» Life History
Movement / Home Range
The heavy pigtoe was historically found in the Tombigbee River from the mouth of Tibbee Creek near Columbus. Mississippi, to Demopolis. Alabama; the Alabama River at Claiborne and Selma, Alabama; the lower Cahaba River, Alabama; and possibly the Coosa River, Alabama (Stansbery 1983a, Williams 1982). Several shells from recently dead specimens were found at one location on the Buttahatchie River. a tributary of the Tombigbee, in Mississippi [Schultz 1981]. This species has also been reported from the East Fork Tombigbee River (Schultz 1981) and from the Sipsey River, Alabama. Only four sites with suitable habitat remain: these consist of localities in a bendway of the Tombigbee River, Sumter County, .Alabama; the East Fork Tombigbee River. Mississippi: the Buttahatchie River, Mississippi; and the Sipsey River, Pickens and Greene Counties, Alabama.
