The salamander mussel (Simpsonaias ambigua) is a unique member of Unionida in that is the only mussel to have a non-fish host. Salamander mussels parasitize large aquatic salamanders known as mudpuppies (Necturus maculosus). Like many other mussels before them, salamander mussels are now being considered for listing under the endangered species act due to widespread population declines. The figure to the right shows the results of survey efforts for both mudpuppies (shaded counties) and salamander mussels (gray and black circles) in Indiana. The gray circles denote streams where old, weathered salamander mussel shells were found and the black circles represent streams where live salamander mussels were found. Use this figure to answer the questions on the following page. 0 35 70 Kilometers Simpsonaias ambigua -live/FD Simpsonaias ambigua - WD/SF VA New Counties since Minton (2001) Minton (2001)
