Mudpuppy (Necturus maculosus) - Threatened
Description: 8 - 13 inches. Mudpuppys are fully aquatic salamanders that retain bright red gills for their entire lives. They are gray or rusty brown in color, with dark speckles and spots throughout the body. Mudpuppys that live in stagnant water with low oxygen will have larger gills than those that live in running streams with higher oxygen.
