Wikipedia Abstract

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. They go through paedomorphosis and retain their external gills, thus resembling axolotls. 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. They are usually a rusty brown color and can grow to an average length of 33 cm (13 in). Mudpuppies are nocturnal creatures, and only come out during the day if the water in which they live is murky. Their diets consist of almost anything they can get in their mouths, including insects, earthworms, mollusks, and annelids. Once a female mudpuppy reaches sex

EDGE Analysis

This unthreatened salamander inhabits the Great Lakes and other major water bodies of North America. It is one of a number of unusual salamanders that do not develop into adults in the normal way, retaining juvenile features and their aquatic lifestyle through sexual maturity. It can breathe using its lungs, its feathery red external gills or through its skin, and in this way can survive in the most poorly oxygenated waters. It spends its time on the bottom of the water, in crevices under rocks and logs, and eats anything from insects to other salamanders.
