Unique mussel that relies on mudpuppy salamanders proposed as endangered

The salamander is the only mussel in North America whose larvae survives on the gills of a salamander. Most freshwater mussels use fish as hosts.

The U.S. Fish and Wildlife Service wants to list a unique mussel native to Indiana as a federally endangered species. The salamander mussel is already a state species of special concern.

It’s the only mussel in North America whose larvae survives on the gills of a mudpuppy salamander. Most freshwater mussels use fish as hosts.

Water pollution, dams, landscape changes, invasive species and risks to the mudpuppy have all caused the salamander mussel’s populations to decline.

Freshwater mussels are very sensitive to water quality changes. According to the Indiana Department of Natural Resources, nearly half of all freshwater mussels in Indiana are either endangered, a species of special concern, or can no longer be found in the state.

The Fish and Wildlife Service has proposed protecting more than 2,000 river miles as critical habitat for the species — including parts of Fish Creek, Big Pine Creek, Middle Fork Wildcat Creek and the Tippecanoe River in Indiana.

The public has until Oct. 23 to  comment on the proposed listing.

WFIU/WTIU News is an independent newsroom rooted in public service.

“Act Independently” is one of the basic creeds of journalism ethics, and we claim it proudly. The WFIU/WTIU News facilities are located on the campus of Indiana University, which does hold our broadcast license and contribute funding to our organization. However, our journalists and senior news leaders have full authority over journalistic decisions — what we decide to cover and how we tell our stories. We observe a clear boundary: Indiana University and RTVS administrators focus on running a strong and secure organization; WFIU/WTIU journalists focus on bringing you independent news you can trust.
