Plethodontid
Plethodontidae, or lungless salamanders, are a family of salamanders. Most species are native to the Western Hemisphere, from British Columbia to Brazil, although a few species are found in Sardinia, Europe south of the Alps, and South Korea. In terms of number of species, they are by far the largest group of salamanders. Biology Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs. Within many species, mating and reproduction occur solely on land. Accordingly, many species also lack an aquatic larval stage, a phenomenon known as direct development in which the offspring hatch as fully-formed, miniature adults. Direct development is correlated with changes in the developmental characteristics of plethodontids compared to other families of salamanders including increases in egg size and duration of embryonic development. Additionally, the evolutionary loss of the aquatic larval stage is related to a diminishing dep ... [...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. 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 lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bradytriton
''Bradytriton'' is a monotypic genus of salamanders in the family Plethodontidae. it is represented by the species ''Bradytriton silus'', commonly known as the Finca Chiblac salamander, and has been considered the sister taxon of the genus ''Oedipina''. It is found in north-western Guatemala and in Chiapas, south-eastern Mexico. Description Adult males measure and adult females in snout–vent length. The body is stocky. The head is relatively broad and essentially continuous with the body. The tail is short and laterally compressed, appearing stout when viewed from the side. The limbs are short and slender with diminutive digits that are, apart from their tips, fused together. Dorsal coloration is reddish brown. The head is mostly black and there are black flecks on the anterior part of the body. The cheeks, sides of the tail, and lower flanks are black with dense white flecks. Habitat and conservation In north-western Guatemala, ''Bradytriton silus'' is known from both distur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolitoglossa
''Bolitoglossa'' is a genus of lungless salamanders, also called mushroom-tongued salamanders, tropical climbing salamanders, or web-footed salamanders, in the family Plethodontidae. Their range is between northern Mexico through Central America to Colombia, Venezuela, Ecuador, Peru, northeastern Brazil, and central Bolivia. Neotropical salamanders of the ''Bolitoglossa'' make up the largest genus in the order Caudata, consisting of approximately one-fifth of all known species of salamanders. Adult salamanders range anywhere from 45mm to 200mm in length depending on their specific species. They are notorious for their ability to project their tongue at prey items, as indicated from their name. They are also known for their webbed feet, having significantly more webbing than any other species outside their genus with the exception of the cave-dwelling Mexican bolitoglossine ''Chiropterotriton magnipes''. Although webbed feet are a common characteristic of these salamanders, only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphiumidae
''Amphiuma'' is a genus of aquatic salamanders from the United States, the only extant genus within the family Amphiumidae . They are colloquially known as amphiumas. They are also known to fishermen as "conger eels" or "Congo snakes", which are zoologically incorrect designations or misnomers, since amphiumas are actually salamanders (and thus amphibians), and not fish, nor reptiles and are not from Congo. ''Amphiuma'' exhibits one of the largest complements of DNA in the living world, around 25 times more than a human. Taxonomy Numerous phylogenetic studies have indicated that amphiumas form a clade with the families Rhyacotritonidae (torrent salamanders) and Plethodontidae (lungless salamanders), with an especially close relationship to Plethodontidae. Despite this possible relationship, the two families must have still diverged very early on. The genus ''Proamphiuma'' from the Cretaceous is the earliest known member of the family, and closely resembles the modern species ...
