Description

A single juvenile mudpuppy approximately 5 inches long was observed. Habitat: littoral zone of inland lake; gravel substrate with small woody debris in water 12 inches deep. elevation: 743 ft. Moon phase: waxing crescent.

Jay Glase, National Park Service fisheries biologist, and Glenn Miller, US Fish and Wildlife Service fisheries biologist, subsequently reported that they had caught a mudpuppy between 10 and 11 inches long in a gill net in Grand Sable Lake on September 28, 2011.

Mr. Guy ("Brody") Block, Pictured Rocks National Lakeshore summer employee and Grand Marais, Michigan, life-long resident, subsequently reported that he had caught a 10 inch long mudpuppy in Grand Sable Lake in ca. 1982 while fishing along the eastern shore of Grand Sable Lake, south of the boat launch.

Description

Date: Jan.8.14

Time: 9:30 pm

Weather Conditions: -14 C (-18 windchill). Mostly Clear Skies.

Habitat Type: Creek.

Possible Threats : A road/bridge runs over the creek area so runoff and contaminants could degrade the water.

Observations: Approximately 104 Necturus maculosus were seen in the middle of the creek area. Most of the water was frozen, except in the middle portion just adjacent to the current. Here the animals could be seen clearly on the bottom. Both sub-adult and adult animals.

The common mudpuppy (Necturus maculosus) is a species of salamander in the genus Necturus. They live an entirely aquatic lifestyle in the eastern part of North America in lakes, rivers, and ponds. Mudpuppies go through paedomorphosis and retain their external gills. Because skin and lung respiration alone is not sufficient for gas exchange, mudpuppies must rely on external gills as their primary means of gas exchange. Mudpuppies are usually a rusty brown color and can grow...
