Necturus
''Necturus'' is a genus of aquatic salamanders native to the eastern United States and Canada. They are commonly known as waterdogs and mudpuppies. The common mudpuppy ''(N. maculosus)'' is probably the best-known species – as an amphibian with gill slits, it is often dissected in comparative anatomy classes. Taxonomy The genus is under scrutiny by herpetologists. The relationship between the species is still being studied. In 1991 Collins elevated ''N. maculosus louisianensis'' to full species status, usually considered a subspecies of the common mudpuppy (''N. maculosus''), but his interpretation was not largely followed.Petranka, J.W.

Necturus Maculosus
The common mudpuppy (''Necturus maculosus'') is a species of salamander in the genus ''Necturus''. They live an entirely aquatic lifestyle in parts of North America in lakes, rivers, and ponds. They 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. They are usually a rusty brown color and can grow to an average length of .Gans, C., and R. A. Nussbaum (1981). "The Mudpuppy." ''Vertebrates, a Laboratory Text.'' Ed. Norman K. Wessells and Elizabeth M. Center. 2nd ed. Los Altos, Calif.: W. Kaufmann, pp. 108–41. Mudpuppies are nocturnal creatures, and come out during the day only if the water in which they live is murky. Their diet consists of almost anything they can get in their mouths, including insects, mollusks, and earthworms (as well as other annelids).

Necturus Moleri
The Apalachicola waterdog (''Necturus moleri'') is a species of aquatic salamander in the family Proteidae. It is endemic to the south-eastern United States. Taxonomy It was formerly thought to be a lineage of the Gulf Coast waterdog (''N. beyeri''), but a 2020 analysis found sufficient morphological and genetic divergence for it to be considered its own species, and it was thus described as its own species, ''N. moleri'' (alongside the Escambia waterdog, ''N. mounti''). The specific epithet honors American herpetologist Paul E. Moler. Distribution It is found in southeastern Alabama, the Panhandle of Florida, and southwestern to north-central Georgia. It is found in the Apalachicola, Chipola, Choctawhatchee/ Pea, Econfina, and Ochlockonee river basins A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean.

Dwarf Waterdog
The dwarf waterdog (''Necturus punctatus'') is an aquatic salamander endemic to the Eastern United States. It is the smallest member of the family Proteidae. Description This species is usually between long. It has bushy, narrow gills and a compressed tail. All feet have four toes. The salamander is uniform slate gray to brown or dark olive dorsally and dirty white ventrally. Most individuals have no dorsal spots; when the dorsal spots are present, the venter is unspotted (unlike in ''Necturus lewisi'', which is also a larger species). Juveniles are uniformly brown dorsally (as opposed to striped, as in other juvenile ''Necturus''). Geographic range ''Necturus punctatus'' is found on the Atlantic coastal plain and the Piedmont of the eastern United States, from southeastern Virginia to southcentral Georgia. Populations further west into Alabama and Florida Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the ...

Red River Mudpuppy (Necturus Maculosus) (42694782124)
The Red River waterdog (''Necturus louisianensis''), also called Louisiana waterdog, is a species of aquatic salamander in the family Proteidae. Taxonomy Some taxonomic authorities consider this salamander to be a subspecies of the common mudpuppy (''N. maculosus)'' as ''N. maculosus louisianensis'', or the Red River mudpuppy. The Red River waterdog was proposed as a separate species from the common mudpuppy by Collins in 1991 and 1997, but supporting data was lacking. Petranka (1998) and Crother (2000) both treated this animal as a subspecies.Geoffrey Hammerson (2004''Necturus maculosus'' In: IUCN 2012. IUCN Red List of Threatened Species. Version 2012.2. Phylogenetic and morphological analyses done by Chabbaria ''et al.'' 2018, confirmed them as being distinct species''.'' However, some authorities still keep it as a subspecies.
