Went to a petshop and saw some of what I think are Necturus maculosus. All are about 12" long, however the guy there says that one is even turning into a salamander because he's losing his gills. Well, looking at him I can see that his mouth form is changing, he's getting some dark spots, and that his gills look to be gone. But don't all mudpuppies keep their gills? Because of his large size I'm just not sure of what he really is. I've seen Eastern Tiger sallies metamorph from waterdogs, and when they've changed they were only probably 5" long at the time. I've also read where gills on mudpuppies can vary in size due to water conditions, however I don't see any left on the one; it has me wondering what kind of mudpuppy or salamander he is.
