Proteidae
The family Proteidae is a group of aquatic 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 into the end of the Late Cretaceous, with ''Paranecturus'' being known from the Maastrichtian of North America. Taxonomy Proteidae, is divided into two extant genera, ''Necturus'' with five North American species, and ''Proteus'' with one extant European species, the olm. A number of extinct genera are known extending back to the end of the Late Cretaceous.

Proteus Bavaricus
The olm or proteus (''Proteus anguinus'') is an aquatic salamander in the family Proteidae, the only exclusively cave-dwelling chordate species found in Europe. In contrast to most amphibians, it is entirely aquatic, eating, sleeping, and breeding underwater. Living in caves found in the Dinaric Alps, it is endemic to the waters that flow underground through the extensive limestone bedrock of the karst of Central and Southeastern Europe in the basin of the Soča River ( it, Isonzo) near Trieste, Italy, southwestern Croatia, and Bosnia and Herzegovina. Introduced populations are found near Vicenza, Italy, and Kranj, Slovenia. It is also called the "human fish" by locals because of its fleshy skin color (translated literally from sl, človeška ribica, mk, човечка рипка, hr, čovječja ribica, bs, čovječja ribica sr, човечја рибица), as well as "cave salamander" or "white salamander".

Apalachicola Waterdog
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 The western waterdog (''Necturus beyeri'') is a species of aquatic salamander in the family Proteidae. It is Endemism, endemic to the southeastern United States, where it occurs in Alabama, Louisiana, Mississippi, and Texas. Taxonomy This may ... (''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 Binomial nomenclature, specific epithet honors American herpetologist Paul E. Moler. Distribution It is found in southeastern Alabama, the Florida Panhandle, Panhandle of Florida, and southwestern to north-central Georgia (U.S. state), Georgia. It is foun ...

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. (1998). Salamanders of the United States and Canada. Smithsonian Institution Press . However, a 2018 study confirmed it as a distinct species, with Amphibian Species of the World following these results, although other authorities do not.''''

Western Waterdog
The western waterdog (''Necturus beyeri'') is a species of aquatic salamander in the family Proteidae. It is endemic to the southeastern United States, where it occurs in Alabama, Louisiana, Mississippi, and Texas. Taxonomy This may be a species complex that could be split into different taxa as research indicates;NatureServe. 2015''Necturus beyeri''.NatureServe Explorer Version 7.1. Retrieved 25 June 2016. the Apalachicola (''N. moleri'') and Escambia (''N. mounti'') waterdogs were split from this species in 2020; previously, they were all grouped together as the Gulf Coast waterdog. It is closely related to '' Necturus alabamensis''.IUCN SSC Amphibian Specialist Group. 2014''Necturus beyeri''.The IUCN Red List of Threatened Species 2014. Retrieved 25 June 2016. Studies indicate that as currently defined, it comprises four lineages: the "Mobile" lineage (ranging from the Mobile River to the Biloxi River), the "Pearl" lineage (ranging from the Wolf River to the Pearl Rive ...

Escambia Waterdog
The Escambia waterdog (''Necturus mounti'') is a species of aquatic salamander in the family Proteidae. It is endemic to the southeastern 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. mounti'' (alongside the Apalachicola waterdog, ''N. moleri''). The specific epithet honors American herpetologist Robert H. Mount. Distribution It is found in southern Alabama and the Panhandle of Florida. It is found in the Blackwater, Escambia/Conecuh, Perdido, and Yellow 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 Waterdog
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. Geographic range It is found in southeastern Kansas, southern Missouri, northeastern Oklahoma, Arkansas, and northcentral Louisiana. It lives only ...

Salamanders
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. 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 rarely 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. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
