Mudpuppies
''Necturus'' is a genus of aquatic salamanders in the family Proteidae. Species of the genus are 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. The common mudpuppy has the largest distribution of any fully aquatic salamander in North America. Taxonomy The genus ''Necturus'' is under scrutiny by herpetologists. The relationship between the species is still being studied. In 1991, Collins recommended ''N. maculosus louisianensis'' be elevated to full species status as ''N. louisianensis''. Originally described by Viosca as a species, it is usually considered a subspecies of the common mudpuppy (''N. maculosus''). However, the interpretation of Collins was not largely followed.

Necturus Maculosus
The common mudpuppy (''Necturus maculosus'') is a species of salamander in the Family (biology), family Proteidae. 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. 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. It is usually a rusty brown color and can grow to an average total length (including tail) of .Carl Gans, Gans, C., and Ronald Archie Nussbaum, R.A. Nussbaum (1981). "The Mudpuppy". pp. 108–141.

Red River Waterdog
The Red River mudpuppy (''Necturus maculosus louisianensis''), also called Louisiana waterdog or Red River waterdog, is a subspecies of aquatic salamander in the family Proteidae. Taxonomy Most taxonomic authorities currently hen?consider this salamander to be a subspecies of the common mudpuppy (''N. maculosus''): ''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, but supporting data was lacking. Petranka (1998) and Crother (2017) both treated this fully aquatic salamander as a subspecies. Phylogenetic and morphological analyses conducted by Chabbaria ''et al.'' 2018, suggested two distinct lineages of ''N. maculosus'' in the Great Lakes and Mississippi River, and similar results were obtained from analyses of mitochondrial DNA (mtDNA) samples from the upper Midwest, Great Lakes, and New England by Greenwald ''et al.'' 2020.

Proteidae
The family (biology), family Proteidae is a group of aquatic Salamander, salamanders found today in the Balkan Peninsula and North America. The range of the genus ''Necturus'' (commonly known as waterdogs or mudpuppies) runs from southern central Canada, through the midwestern United States, east to North Carolina and south to Georgia and Mississippi. The range of the olm, the only extant member of the genus ''Proteus'', is limited to the Western Balkans. The fossil record of the family extends back to the Late Cretaceous, with ''Paranecturus'' being known from the Maastrichtian of North America, and ''Bishara (salamander), Bishara'' from the Santonian-Campanian of Central Asia. Taxonomy Proteidae, is divided into two extant taxon, extant genera, ''Necturus'' with five North American species, and ''Olm, Proteus'' with one extant European species, the olm. A number of extinct genera are known extending back to the end of the Late Cretaceous. Family Proteidae * Genus ''Nectu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela, the sole surviving order from the group Caudata. ''Urodela'' is a scientific Latin term based on the Ancient Greek : ourà dēlē "conspicuous tail". ''Caudata'' is the Latin for "tailed ones", from : "tail". Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders never have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...
