Texas pimpleback mussel held by river

A live Texas pimpleback mussel found at a research site on the San Saba River in Central Texas July 30, 2020. A team of researchers from Texas A&M AgriLife Research and The Nature Conservancy are working on a project funded by U.S. Fish and Wildlife Service Ecological Services to study how the extreme low and high flows that plague the San Saba River impact populations of rare mussel species and how climate change might exacerbate their struggle to survive.
