Pseudotriton
''Pseudotriton'' is a genus of salamanders in the family Plethodontidae. They are endemic to eastern and southern United States, from New York south to Florida and west to southern Ohio, Kentucky, Tennessee, and eastern Louisiana. They are commonly known as red salamanders or mud salamanders. Species The number of species depends on the source. The Amphibian Species of the World lists the following four species: * '' Pseudotriton diastictus'' Bishop, 1941 — midland mud salamander * '' Pseudotriton flavissimus'' (Hallowell, 1856) — Gulf Coast mud salamander * '' Pseudotriton montanus'' Baird, 1850 — mud salamander * '' Pseudotriton ruber'' (Sonnini de Manoncourt and Latreille, 1801) — red salamander However, AmphibiaWeb lists only two species as it treats ''Pseudotriton diastictus'' and ''P. flavissimus'' as subspecies of ''Pseudotriton montanus'', as does the International Union for Conservation of Nature The International Union for Conservation of Nature (IUCN) i ...

Mud Salamander
The mud salamander (''Pseudotriton montanus'') is a bright red salamander of the family Plethodontidae. It is found in streams, seeps and swamps and underneath logs, rocks and leaves. It is endemic to the eastern half of the United States with one isolated population in central Mississippi. Mud salamanders are rarely seen plethodontids that inhabit muddy wetland and riparian habitats. Mud salamanders don’t generally live above 700 meters in elevation in the Appalachian Mountains, resulting in two geographically isolated populations. Mud salamanders have short stocky bodies ranging from 7.5 to 16 cm long. Body color ranges with age and locality. There are four subspecies in the mud salamander complex, namely the Gulf Coast mud salamander, rusty mud salamander, Midland mud salamander and the eastern mud salamander. Mud salamanders are ectothermic, meaning that they cannot control their body temperature and it fluctuates with the temperature. The mud salamander is readily confus ...

Red Salamander
The red salamander (''Pseudotriton ruber'') is a species of salamander in the family (Plethodontidae) (lungless salamanders) endemic to the Eastern United States. Its skin is brown, orange or red with random black spots. Semiaquatic adults and aquatic larvae live in temperate forests, small creeks, bogs, ponds, intermittent streams, and freshwater springs. Overall this species is common and widespread, but locally it has declined because of habitat loss and it is considered threatened in Indiana and New York. Red salamanders eat insects, earthworms, spiders, small crustaceans, snails, and smaller salamanders. To eat, they extend their tongue to capture prey on the tip of it and retract it back into their mouths. The red salamander, as a member of the family Plethodontidae (lungless salamanders) lacks lungs and respires through its skin. Description ''The Pseudotriton ruber'' is a medium-large salamander, with adults ranging from in total length. It has a relatively stout body w ...

''Pseudotriton'' is a genus of salamanders in the family Plethodontidae.

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] |
Plethodontidae
Plethodontidae, or lungless salamanders, are a family of salamanders. With over 500 species, lungless salamanders are by far the largest family of salamanders in terms of their diversity. Most species are native to the Western Hemisphere, from British Columbia to Brazil. Only two extant genera occur in the Eastern Hemisphere: '' Speleomantes'' (native to Sardinia and mainland Europe south of the Alps) and '' Karsenia'' (native to South Korea). 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 durat ...

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Johannes Von Nepomuk Franz Xaver Gistel
Johannes von Nepomuk Franz Xaver Gistel [Gistl] (11 August 1809 – 9 March 1873) was a German naturalist. He worked at the Museum of Natural History in Regensburg, and wrote on a range of topics under the pseudonyms Garduus and G. Tilesius (an anagram). His contributions to entomology include descriptions of species, with many new names he proposed now mostly relegated to synonymy. Gistel's father Franz Xaver Gistl (1783–1815) worked at a royal riding school and died in 1813. Gistel was raised by his mother, Maria Anna Gistl (née Hahn, born 1772) and his older sister Katharina Leonora (born 1808). School records indicate that his original name was Lorenz Gistl. He was educated in schools in Rempart and Schönfeld before joining the royal gymnasium in Munich in 1822. His degrees in medicine and philosophy appear to be fake. He wrote works on entomology such as ''Die jetzt lebenden Entomologen, Kerffreunde und kerfsammler Europa’s und der übrigen Continente'' (1836) and ''Ac ...
