The common mudpuppy (Necturus maculosus) is a species of salamander in the family Proteidae.[4] It lives an entirely aquatic lifestyle in parts of North America in lakes, rivers, and ponds. It goes through paedomorphosis and retains its external gills.[5] Because skin and lung respiration alone is not sufficient for gas exchange, the common mudpuppy must rely on external gills as its primary means of gas exchange.[6] It is usually a rusty brown color[7] and can grow to an average total length (including tail) of 13 in (330 mm).[8] It is a nocturnal creature, and is active during the day only if the water in which it lives is murky.[4] Its diet consists of almost anything it can get into its mouth, including insects, mollusks, and earthworms (as well as other annelids).[7] Once a female common mudpuppy reaches sexual maturity at six years of age, she can lay an average of 60 eggs.[7] In the wild, the average lifespan of a common mudpuppy is 11 years.[9]
