Adult mudpuppy, approximate length 15 inches; note the extended gills behind the head, just in front of the legs.
In Massachusetts, Necturus maculosus is restricted to the Connecticut River and two small lakes in the western part of the state. Because of its aquatic nature, very little is known about this animal's life history and distribution. To date most information about this species is anecdotal, provided by fisherman who occasionally catch Necturus while angling at night or while ice fishing.
I am most interested in additional information on the distribution and ecology of this species in the Connecticut River and other locations in New England. I would like to know location, date, number of specimens and any other information you can provide about any sightings of this species you may have. I am particularly interested in breeding locations.
