Bolitoglossinae
Bolitoglossinae is a subfamily of lungless salamander. Most of them are native to tropical areas in Central and South America, though a few such as Batrachoseps are found in temperate regions. Its sister group is the extinct genus Palaeoplethodon. {{Taxonbar, from=Q3077933 Plethodontidae Amphibian subfamilies Taxa named by Edward Hallowell (herpetologist) ...

Edward Hallowell (herpetologist)
Edward Hallowell (1808 – February 20, 1860) was an American herpetologist and physician. He studied and practiced medicine in Philadelphia. He also was a renowned herpetologist who described 61 new species of reptiles. In 1851, Hallowell was elected as a member of the American Philosophical Society The American Philosophical Society (APS), founded in 1743 in Philadelphia, is a scholarly organization that promotes knowledge in the sciences and humanities through research, professional meetings, publications, library resources, and communit ....

Parvimolge
''Parvimolge'' is a genus of salamanders in the family Plethodontidae, the lungless salamanders. It is currently considered as monotypic, although this may yet change as molecular data suggest that it is embedded within a paraphyletic '' Pseudoeurycea''. ''Parvimolge townsendi'' is endemic to the northern Sierra Madre de Oaxaca in central and southern Veracruz, Mexico, between 900 and 1900 meters elevation. It is represented by the species ''Parvimolge townsendi'', commonly known as Townsend's dwarf salamander. Habitat and conservation Natural habitats of ''Parvimolge townsendi'' are cloud and oak forests. They are usually found living in bromeliad The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, ...s or on the ground.

Plethodontidae
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] |
Palaeoplethodon Hispaniolae
''Palaeoplethodon hispaniolae'' is an extinct salamander species found in Miocene Dominican amber from the Dominican Republic. It is so far the only salamander species known to have existed in the Caribbean. Discovery and description The only known specimen was a juvenile found in an amber mine in the mountain range between Puerto Plata and Santiago. The amber itself was from the extinct legume species ''Hymenaea protera''. The salamander is missing its left front leg, implying possible predation. Its legs did not have any distinct toes, rather, it had complete webbing with small bumps on it. It most likely lived in small trees or in tropical flowers. It is unknown how this salamander's lineage arrived to the area, and how it became extinct. They may have arrived by a land bridge, or they may have ridden debris to the island. It is possible that their extinction was caused by climate change or by extensive predation. It is most likely a stem-group to the plethodontid t ...

Slender Salamander
''Batrachoseps'' is a genus of lungless salamanders (plethodontids) often called slender salamanders. They can be distinguished from other lungless salamanders by the four toes they have on each foot. Their genus name ''Batracho-seps'' means "frog-lizard", in reference to their projectile tongues. Diet and physiology The lungless salamanders, in addition to having no lungs, have long slender snake-shaped bodies with very small limbs that appear almost vestigial in several species. Their main diet consists of small insects, such as springtails, small bark beetles, crickets, young snails, mites, and spiders. Like all salamanders in this family, they have long frog-like projectile tongues which they use to grab their prey in a flash. Unlike all other amphibians (and birds, and lizards, and nearly all fish) mature red blood cells in species in the genus ''Batrachoseps'' have no nucleus, which is a trait that is only known to occur in mammals and certain species of antarctic fish. ...

Thorius
''Thorius'', also known as minute salamanders, pigmy salamanders, or Mexican pigmy salamanders, is a genus of salamanders in the family Plethodontidae. They are endemic to Mexico and found in southern Veracruz and Puebla to Guerrero and Oaxaca. ''Thorius'' is the most species-rich tropical salamander genus relative to its distribution area (''Bolitoglossa'' and ''Pseudoeurycea'' have many more species but also much wider distribution areas). It is not uncommon for two or even three species to occur in the same place. In such cases, species have diverged in terms of body size and dentition, apparently facilitating niche differentiation. The members of this genus are characterized by a small body — some species are less than in snout–vent length (tail roughly doubles the total body length). Their extreme miniaturization is accompanied by determinate growth and skeletal reduction. Their skeleton also shows unique features, such as ossifications of many elements that remain car ...

Pseudoeurycea
''Pseudoeurycea'' is a genus of salamander in the family Plethodontidae. The members of this genus are commonly known as the false brook salamanders. They are found in Mexico and Guatemala. In order to preserve ''Ixalotriton'' and ''Bolitoglossa'' while avoiding paraphyly of ''Pseudoeurycea'', species in the former "''Pseudoeurycea bellii'' species group" have been moved to the genus ''Isthmura'', and those in the former "''Pseudoeurycea cephalica'' species group" to ''Aquiloeurycea''.

Nyctanolis
''Nyctanolis'' is a monotypic genus of salamanders in the family Plethodontidae. It is represented by the species ''Nyctanolis pernix'', also commonly referred to as nimble long-limbed salamander, which is characterized by its absence of lungs; it instead achieves respiration through its skin and the tissues lining the mouth.
