AUSTIN, Texas— Following litigation by the Center for Biological Diversity, the U.S. Fish and Wildlife Service today proposed to protect six species of Texas freshwater mussels under the Endangered Species Act. The Service also proposed designating 1,944 river miles as critical habitat for the mussels.

The Texas pimpleback, Guadalupe orb, Texas fatmucket, Guadalupe fatmucket and false spike will be listed as endangered under the Endangered Species Act, while the Texas fawnsfoot will be classified as threatened. All six species inhabit the Brazos, Colorado, Trinity and Guadalupe river basins.
