Dusky Salamanders
''Desmognathus'' is a genus of lungless salamanders in the family Plethodontidae known as dusky salamanders. They range throughout the eastern United States as far west as Texas, and north to southeastern Canada. Characteristics Species of the genus ''Desmognathus'' have a unique jaw-opening mechanism where the lower jaw is stationary and the skull swings open. There are additional stalked condyles, an atlanto-mandibular ligament, along with other skeletal and musculature features that have evolved to accompany this type of jaw-opening mechanism. Additionally, they are known to exhibit maternal care by brooding over their eggs. Species This genus Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses.

Desmognathus Kanawha
The Kanawha black-bellied salamander or New River black-bellied salamander (''Desmognathus kanawha'') is a species of lungless salamander in the family Plethodontidae. It is endemic to the eastern United States, where it is only known from the south-central Appalachian Mountains. The northernmost member of the "blackbelly salamander" complex, it is primarily known from the Kanawha River basin of southwestern Virginia and southern West Virginia, but is also known from the upper Pee Dee River basin of northwestern North Carolina and southwestern Virginia, the upper Tennessee River basin of southwestern Virginia and northeastern Tennessee, the Roanoke River basin of north-central North Carolina and south-central Virginia, and the lower Chesapeake River basin of west-central Virginia. It is currently unknown how far southwest and northeast this species ranges.

Desmognathus Imitator
The imitator salamander (''Desmognathus imitator'') is a species of salamander in the family Plethodontidae. It is endemic to the Appalachian Mountains in the southeastern United States. Description The imitator salamander is dark brown or blackish, sometimes with a pale intermittent stripe down its back and a pale line joining eye to jaw. It often has red or orange cheek patches and its hind legs are more stocky than its forelegs. Distribution and habitat The imitator salamander is found in the Appalachian Mountains in Tennessee and North Carolina at elevations more than above sea level. Its range extends from the Great Smoky Mountains in the north to the Plott Balsams and the Great Balsam Mountains in the south. Its habitat is the banks of streams, wet rocks, and the forest floor at higher altitudes. It shares its range with the Ocoee salamander (''Desmognathus ocoee'') but is usually found closer to water. Biology The imitator salamander is not toxic but is thought to be a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desmognathus Gvnigeusgwotli
The Cherokee black-bellied salamander or Smoky Mountains black-bellied salamander (''Desmognathus gvnigeusgwotli'') is a species of lungless salamander in the family Plethodontidae. It is endemic to the eastern United States, where it is only known from the southern Appalachian Mountains. It is known from extreme western North Carolina and southeastern Tennessee. It is restricted mostly to the Great Smoky Mountains, with isolated records also known from the Unicoi, Great Balsam, and Bald Mountains. This is the more common of the two species of "blackbelly salamander" known from Great Smoky Mountains National Park. This species and the other blackbelly salamander from the range (the Pisgah black-bellied salamander, ''D. mavrokoilus'') are the first new vertebrate taxa to be discovered in the park's all-taxa biodiversity inventory. Initially grouped with the blackbelly salamander (''D. quadramaculatus''), a 2022 study found significant genetic divergence within the species, but ...

Desmognathus Fuscus
''Desmognathus fuscus'' is a species of amphibian in the family Plethodontidae (Plethodontidae, lungless salamanders). The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form several distinct species, the southern dusky salamanders (''Desmognathus auriculatus, D. auriculatus, Desmognathus valentinei, D. valentinei''). The northern dusky salamander is the most widespread representative of its genus in Canada. It can be found in eastern North America from extreme eastern Canada in New Brunswick south to South Carolina. The size of the species' total population is unknown, but is assumed to easily exceed 100,000. The species' habitat differs somewhat geographically; dusky salamanders in the northern part of the range prefer rocky woodland streams, seepages, and springs, while those in the south favor floodplains, Swamp, sloughs, and muddy places along upland streams. They are most comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desmognathus Folkertsi
The dwarf black-bellied salamander (''Desmognathus folkertsi'') is a species of salamander in the family Plethodontidae. It is endemic to the United States. Its natural habitats are temperate forests and rivers. The dwarf black-bellied salamander (''Desmognathus folkertsi'') was originally thought to be the blackbelly salamander (''Desmognathus quadramaculatus'') as they appear similar and are sympatric In biology, two closely related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter each other. An initially interbreeding population that splits into two or more distinct spe ... in the areas that the dwarf black-bellied salamander is found. They can be distinguished through genetically different loci or morphologically in that ''D. folkertsi'' are smaller, have different coloration and patterns, and different proportions in body.

Desmognathus Conanti
The spotted dusky salamander (''Desmognathus conanti'') is a species of salamander in the family Plethodontidae. It is endemic to the United States. Taxonomy ''Desmognathus conanti'' was described in 1958 by Douglas A. Rossman, but was later reclassified as a subspecies of the northern dusky salamander (''D. fuscus''). However, numerous genetic and morphological studies since then have affirmed it as being a distinct species and it was elevated to full specific status in 1996. In addition, genetic studies indicate that ''D. conanti'' is paraphyletic with respect to the Santeetlah dusky salamander (''D. santeelah''), which lies nested within it; thus, ''D. conanti'' itself likely represents a species complex of multiple undescribed cryptic species. Range and Habitat ''Desmognathus conanti'' has a wide range in the southeastern and south-central United States, ranging from southern Illinois south to the panhandle of Florida, and west to Louisiana and southern Arkansas ...

Desmognathus Cheaha
The Talladega seal salamander (''Desmognathus cheaha'') is a mid-sized stream-dwelling plethodontid salamander native to the Southeastern United States. This species was split from the common seal salamander (''Desmognathus monticola'') in 2022. Distribution and habitat The Talladega seal salamander can be found in the U.S. States of Georgia, Alabama, and Florida. This species occurs in the Ridge & Valley, Piedmont, and Coastal/Southeastern Plains physiographic provinces, in contrast with ''Desmognathus monticola,'' which predominantly occurs in the Appalachian highlands. The only known population in Florida is believed to have undergone a dramatic population decline, and may be extirpated Local extinction, also extirpation, is the termination of a species (or other taxon) in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a chan ..., after nearby logging activities impac ...
