A bizarre salamander and the endangered, clam-like mussel that relies on it got good news recently from Canadian scientists. Federal researchers found an apparently stable population of mudpuppies in Ontario’s Sydenham River. The research is published in the June issue of the Journal of Great Lakes Research. Mudpuppies are native to the Great Lakes and have beady eyes, slimy skin and feathery gills sticking out of their necks. “I find them very interesting animals, but I can see why the general public wouldn’t rate them up there with bluebirds,” said Jim Harding, herpetology specialist at the Michigan State University Museum.
