The heavy pigtoe or Judge Tait's mussel (Pleurobema taitianum) is a type of freshwater mussel. Mussels are aquatic animals that live in water. They are a kind of bivalve mollusk, which means they have two shells that hinge together. This mussel belongs to the family Unionidae, known as river mussels.
This special mussel is found only in the United States. It used to live in several rivers, including the Tombigbee, Alabama, Coosa, and Cahaba rivers. Today, it is mostly found only in the Alabama and Coosa River systems. Scientists are worried because a survey in 2010 found no signs of new young mussels growing. This means the species might already be gone.

Meet the Heavy Pigtoe Mussel
The heavy pigtoe mussel gets its name from its thick, heavy shell. It's an important part of the river ecosystem. Mussels help keep rivers clean by filtering water. They are like tiny natural water purifiers.
Where Does It Live?
This mussel is endemic to the southeastern United States. This means it naturally lives nowhere else in the world. It once had a wider range across several rivers. These included the Tombigbee, Alabama, Coosa, and Cahaba rivers. It might have also lived in the Black Warrior.
Sadly, its population has shrunk a lot. Now, it is mainly found in the Alabama and Coosa River systems. Some smaller populations were thought to be in tributaries of the Tombigbee River. These included the Buttahatchie, East Fork Tombigbee, and Sipsey rivers.
Why Is It Endangered?
The heavy pigtoe mussel is a federally endangered species. This means it is protected by a special law called the Endangered Species Act of 1973. It received this protection in 1987.
What Caused the Decline?
One major reason for its decline was the building of the Tennessee–Tombigbee Waterway. This big canal project changed the flow of the Tombigbee River. It trapped some mussels in parts of the river that were cut off. This made it hard for them to survive.
Other projects by the U.S. Army Corps of Engineers also caused problems. For example, a creek called Bull Mountain Creek was redirected. This creek fed into the East Fork Tombigbee River. The redirection made the river water warmer, which is bad for mussels. Changes in water temperature and flow can harm these sensitive animals.
Protecting This Mussel
Protecting the heavy pigtoe mussel is very important. Scientists and conservation groups are working to save it. They try to protect its remaining habitats. They also work to improve water quality in the rivers where it lives. Saving this mussel helps keep our rivers healthy for everyone.
