Pseudotriton ruber is a stout-bodied, medium-sized salamander ranging between four and seven inches (10 to 18 cm) in length. There are a few major field marks that can be used to identify this salamander. The dorsum and sides of this salamander vary from a purplish brown to a bright crimson red. Younger specimens are brighter in color, while adults tend to darken with age. The dorsum is also covered with irregularly shaped dark spots or dashes. There are five toes located on the hindlimbs and four toes on the forelimbs. There is also a slight mid-dorsal grove and sixteen or seventeen costal grooves (Conant and Collins, 1998; Harding, 1997).
Other Physical Features: ectothermic ; bilateral symmetry
Average lifespan
Status: captivity: 20.1 years.
The Red Salamander can be found in terrestrial or aquatic environments, but are aquatic in winter. In the terrestrial environment they can typically be found in wooded areas under fallen bark, logs, and rocks. Their aquatic preference is in the leaf litter of clean running, cool streams and brooks (Harding, 1997; Petranka, 1998).
Terrestrial Biomes: forest
Aquatic Biomes: rivers and streams
Pseudotriton ruber is found in the Eastern United States from Northern Alabama, Georgia, South Carolina, and North Carolina, to western Ohio, Pennsylvania, New Jersey, and Southen New York. Pseudotriton ruber is usually found between sea level and 1500 ft. Although specimens are rare above 1200 ft. populations have be found near 3900 ft (Conant and Collins, 1998; Harding, 1997).
Biogeographic Regions: nearctic (Native )
This salamander is a carnivore, feeding on small insects, worms, and other invertebrates, and occasionally smaller salamanders. Larvae eat small aquatic invertebrates One interesting adaptation of this salamander is a projectile tongue, which it can extend and return in 11 milliseconds. The salamander also lunges forward during prey capture. Pseudotriton ruber can be found searching for prey during and after rain events, especially at night. (Pfingsten and Downs, 1989; Harding, 1997; Petranka, 1998).
Woodland salamanders play a significant ecological role as predators, prey, and cyclers of nutrients in the woodland and stream habitats they live in (Petranka, 1998).
Development - Life Cycle: metamorphosis
Because Pseudotriton ruber requires intact deciduous forests and clean streams, this species can be severly impacted by deforestation, pollution, acid drainage from coal mines, and stream siltation and warming (Harding, 1997).
US Federal List: no special status
CITES: no special status
IUCN Red List of Threatened Species: least concern
Pseudotriton ruber displays aquatic courtship from spring through fall; courtship involves the male rubbing his snout on the female's head and chin, and eventually moving forward as the female follows with her chin on the male's tail. The male then deposits a spermatophore to be picked up by the female with her cloaca. Females may lay eggs until several months after courting and are capable of storing sperm for a long period of time. The females lay their eggs in cryptic locations during autumn in springs, brooks, and under streambanks. The eggs are attached to the underside of rocks by a single gelatinous stalk and are often submerged in the water. On average the female will lay between 30 - 130 eggs. The eggs hatch in early winter and there is a larval stage lasting between two and three years. Metamorphosis takes place during the summer months. Red Salamanderrs can live over 20 years (Pfingsten and Downs, 1989; Harding, 1997; Petranka, 1998).

La salamandra vermella (Pseudotriton ruber) és una espècie de salamandra de la família Plethodontidae. És endèmica als Estats Units. Es distribueix en el costat atlàntica del país, encara que aquesta absent en gran part de la costa.
Els seus hàbitats naturals són els boscos, muntanyes de matolls, rius, i deus d'aigua dolça. Es troben sempre prop de l'aigua, en la fullaraca o sota roques. Pon els seus ous enganxats a roques en l'aigua.
Der Rotsalamander (Pseudotriton ruber) ist ein Schwanzlurch aus der artenreichen Familie der Lungenlosen Salamander (Plethodontidae).
Die Haut der 10 bis 15 Zentimeter langen Tiere ist purpur-braun bis karminrot gefärbt und weist unregelmäßige dunkle Flecken auf. Die Jungtiere erscheinen heller als die Alttiere.[1]
Gegen seine Fressfeinde, wie Waldvögel, Stinktiere oder Waschbären, entwickelt die Art ein Hautgift, welches früher als Pseudo Tritotoxin bezeichnet wurde.[2] Dabei handelt es sich um nicht näher bestimmte Giftstoffe, zu denen auch Leptoxin gehört.[3]
Der Rotsalamander lebt in den südöstlichen USA, südlich von New York bis östlich des Deltas des Mississippi River in feuchtkühlen Wäldern und Quellbereichen bis in 1500 Metern über Meereshöhe. Er ist sowohl wasser- als auch landlebend; im Winter hält er sich nur im Wasser auf.[4] An Land verbergen sich die Tiere unter Steinen, Rinden- und Holzstücken.
Zur Nahrung zählen praktisch alle zu überwältigenden Tiere.[5] Gelegentlich werden auch andere kleine Salamander gefressen. Kleine Beutetiere werden mit der Schleuderzunge gefangen, die innerhalb von elf Millisekunden hervorgeschnellt und wieder eingezogen werden kann.[6]
Die Paarungszeit dauert vom Frühling bis in den Herbst. Das Weibchen kann das Sperma in seinem Körper speichern und legt im frühen Herbst im Wasser unter Steinen oder Holz 50 bis 100 Eier ab. In den ersten Wintermonaten schlüpfen circa zwei Zentimeter lange Larven. Nach 27–31 Monaten Wasseraufenthalt durchlaufen die Jungtiere die Metamorphose und gehen an Land.[7] Bei Männchen erfolgt die Geschlechtsreife meist mit einer Größe von 53–63 mm (üblicherweise nach 4 Jahren), bei Weibchen meist mit einer Größe von 55–68 mm (üblicherweise nach 5 Jahren).[8]
Der Rotsalamander (Pseudotriton ruber) ist ein Schwanzlurch aus der artenreichen Familie der Lungenlosen Salamander (Plethodontidae).
The red salamander (Pseudotriton ruber) is a species of salamander in the family Plethodontidae endemic to the eastern United States. Its skin is orange/red with random black spots. Its habitats are temperate forests, small creeks, ponds, forests, temperate shrubland, rivers, intermittent rivers, freshwater, trees springs. Overall this species is common and widespread,[1] but locally it has declined because of habitat loss and it is considered threatened in Indiana.[2] 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.[3] The red salamander, as a member of the family Plethodontidae (lungless salamanders), lacks lungs and respires through its skin.[4]
Pseudotriton ruber is a medium-large salamander, with adults ranging from 4.3 to 7.1 in (11–18 cm) in total length.[4] Its sides and back vary in color from an orange-brownish tint to a bright red depending on its age. Like other salamanders, the red salamander seems to lose its color as it ages, becoming more darkly pigmented with less obscure patterns.[5] The larvae of this species have a stout head and body, dark in coloration, lack spots, and tend to have distinct mottling or streaks.[6] Another distinguishing characteristic of P. ruber is the appearance of numerous irregular black spots down its back. Although the red salamander is brilliantly colored and has many distinguishing features, it is sometimes difficult to tell species apart. P. ruber is most similar in appearance to the mud salamander (P. montanus), but can be distinguished by the difference in size and number of spots running down the dorsum and also by the difference in the color of the iris. Both P. ruber and P. montanus have bright red colorations that have been considered examples of a Müllerian mimetic complex.[7] The red salamander has more spots and the spots also tend to be larger in size than those of the mud salamander. In regard to eye color, the red salamander's iris is a gold-like tint, whereas the mud salamander's iris is brown.[8] The gold-like tint iris for the red salamander is also disgusting by its horizontal bar that runs through the iris.[9] Mud salamanders typically have a blunter snout than the red salamander.[5] Also, the mud salamanders typically have a more contrasting dorsal and ventral coloration than the red salamanders that are more uniform in color.[5]
In the Plethodontidae (lungless salamanders), many members respire through their skin and the lining in their mouths. Lunglessness in this family may have evolved due to an adaptation for life in streams, and members of the family Plethodontidae probably did evolve other methods for respiration other than lungs (i.e. gills) due to enhanced survival of larval salamanders in fast-moving stream environments of southern Appalachia.[10][11] Lungs in general help aquatic animals maintain position in the water column, but the larvae of Plethodontidae members are benthic creatures, therefore the adaptation of lunglessness would be beneficial to them since buoyancy would endanger their survival.[11] The red salamander is further classified as a member of the genus Pseudotriton. Members of this genus include only the red salamander and the mud salamander.
The four subspecies of P. ruber are found across the eastern United States, occupying streams through open areas such as fields and meadows, as well as aquatic areas through forested areas and mountains. Each subspecies is similar in appearance with slight differences in size and coloration, but are found in different habitats. The northern red salamander, P. r. ruber, is characterized as being red or reddish-orange with numerous black spots down its back. This subspecies is the most common and can be found from southern New York and Ohio to northeast Alabama, as well as the Upper Peninsula of Michigan.[5] Similar in appearance to the northern red salamander is the Blue Ridge red salamander, P. r. nitidus. This species differs it is slightly smaller and lacks black coloration on the tip of the tail and chin.[5] The Blue Ridge red salamander is found in elevations to more than 5,000 ft (1,500 m) in the southern part of the Blue Ridge Mountains of Virginia.[5] The blackchin red salamander, P. r. schencki, differs in appearance by having strong black coloration under its chin, as well as spotting all the way to the tip of the tail.[5] It can also be found in elevations to more than 5,000 ft (1,500 m) in the Blue Ridge Mountains.[5] The southern red salamander (P. r. vioscai) is often purplish- to salmon-colored and normally has white spots on its head. This subspecies is found from southern South Carolina to southeast Louisiana and southwest Kentucky. All subspecies of P. ruber occupy moist environments such as under moss and stones near clear water sources such as streams or springs.[5] Red salamanders are normally not found near large streams, but instead near smaller water sources.[12]
Some important aquatic and terrestrial ecological aspects of this salamander include its diet, predators, and microhabitat preferences. Larvae mainly feed on invertebrates such as insect larvae and worms.[13] Larvae diet specifically has been shown to consist of Chironomidae (36.52% of prey items) and Sphaeriidae (15.17%) as well as terrestrial prey (7.87%) and other salamanders.[14] Larval growth rates differ depending on the temperature of the water and tend to be higher in the warmer months when water temperature is higher.[12][15] The red salamander generally lays eggs in the fall and hatching season takes place in the late fall and winter.[15] The larval period varies between 27 and 31 months and then metamorphosis takes place in the spring and early summer of the third year.[15] Larval red salamanders are generalists, eating whatever is available.[16] Feeding rates typically increase when water temperature is low and larger individuals feed more than smaller individuals.[16] Although feeding rates appear to increase with increasing size, mortality rates, though, seem to be independent of size or age and survival is estimated to be about 50% per year.[15] The longer larval period ensures that transformation occurs when the salamanders are much larger than other species of salamanders and typically have a short juvenile period, maturing quickly.[12] Larval duration and size at metamorphosis decrease with increasing elevation.[17] Males mature at about 53–63 mm (2.1–2.5 in), typically at four years of age, and females mature at about 55–68 mm (2.2–2.7 in), typically at about five years of age.[12]
Red salamanders generally live in springs or streams during the winter and then disperse to and from these sites in the fall and spring.[18] Due to its semiaquatic nature, the red salamander remains in terrestrial environments until early spring then disperses to more aquatic sites.[12] Adults often live in burrows along streams and in other moist environments such as under logs and rocks along the forest floor.[13] Adult red salamanders, like their larvae, are generalists and tend to feed on invertebrates (such as earthworms, slugs, snails, spiders, diving beetles and other insects),[19] as well as small amphibians,[13] including the red-backed salamander.[19] Its predators include birds and small carnivores such as skunks and raccoons.[12] Since the red salamander is a large species of salamander, its presence or absence can greatly affect the ecosystem where it lives, and understanding its ecology is important to understand its role in community structures.
P. ruber has a wide range in its breeding season, which is only limited by extremely cold temperatures.[12] Adults are known to migrate from streams and bodies of water to terrestrial habitats during specific seasons each year. They will then return to aquatic streams in the late summer and early fall to begin breeding.[20] Generally, however, adult red salamanders mate annually and engage in primitive courting activities.[18][21] Courtship between two red salamanders involves:
"A male approaches a female, rubbing his snout against her snout, cheeks, and chin. The male then moves his head and body under her chin and starts tail undulations. The female then straddles the male's tail and the pair engages in a straddled 'walk' until the male deposits sperm on the substrate. The 'straddle-walk' approximately lasts two minutes and once the sperm is deposited, the female picks up the sperm cap as she moves over it and then they separate."[21]
Females are capable of long-term sperm storage and may not lay eggs for months after mating.[12] Females typically lay eggs in the fall or early winter in headwater streams, and have very well-hidden nests.[13]
Based on presence of scars and hypertrophied jaws in mature males, it is suggested that male P. ruber might be involved in mate-guarding behavior.[22] Males occasionally court other males as a means of sperm competition to get the other male to deposit spermatophores, giving them a better chance of successful mating over their competitors.[21]
Other important behavioral aspects of P. ruber include its defensive mechanisms. When threatened, red salamanders assume a defensive posture in which they curl their bodies, elevating and extending their rears, and placing their heads under their tails which are elevated and undulated from side to side.[23] The coloration of the red salamander has been hypothesized to mimic that of the red eft stage of the eastern newt (Notophythalmus viridescens) which emits a powerful neurotoxin in their skin.[24] This phenomenon is known as the Mullerian Mimicry Complex.[25] However, this hypothesis was heavily criticized due to significant size differences in the organisms and the differences in the species' times of foraging ( i.e. P. ruber mainly at night and the red eft mainly during the day).[26] More recently, red salamanders have been noted to have reduced palatability, so they are considered part of a Müllerian mimicry system in which all species are unpalatable and benefit from aposematic coloration.[12] In human trials, subjects reported no noxious or repulsive taste of Red Salamanders.[27]
Overall the red salamander is common and widespread,[1] but locally it has declined because of habitat loss and it is listed as an endangered species in Indiana.[2]
The red salamander is arguably one of the most primitive plethodontids, so is extremely valuable in understanding the links to ancestors and the evolutionary processes that have occurred.[21] Maintaining species diversity is an important part of conservation, and to prevent the loss of salamander diversity as a whole, it is important to have some type of management plan in place to prevent P. ruber from escalating from a low conservation status to a higher level of concern. Since the red salamander prefers streams that are relatively pure, it is important to monitor human waste and pollution, since debris and silt could have adverse effects on their habitat, potentially causing a threat to survival.

Pseudotriton ruber
La Salamandre rouge (Pseudotriton ruber) est une espèce d'urodèles de la famille des Plethodontidae.
De rode salamander[2] (Pseudotriton ruber) is een salamander uit de familie longloze salamanders (Plethodontidae). De soort werd voor het eerst wetenschappelijk beschreven door Charles-Nicolas-Sigisbert Sonnini de Manoncourt en Pierre André Latreille in 1801. Oorspronkelijk werd de wetenschappelijke naam Salamandra rubra gebruikt.[3]
Deze salamander is meestal helemaal rood, behalve de buik, deze is lichter tot grijswit. Op de rug, poten en staartbasis zitten vele kleine zwarte vlekjes die qua aantal variëren, bij sommige exemplaren zitten er maar enkele tientallen, bij andere vele honderden en ook de kleur kan wat oranje of zelfs bruinachtig zijn. Het lichaam is uitgerekt en rond en heeft duidelijk zichtbare ribben, vrij kleine poten en ogen en een korte en sterk afgeplatte staart. De salamander bereikt een maximale lichaamslengte van ongeveer 20 centimeter. De kop is groot en rond en is tevens duidelijk door de nek afgesnoerd.[4]
Het voedsel van deze nachtactieve salamander bestaat uit insecten, kleine amfibieën en wormen. Net zoals een kameleon heeft het dier een schiettong waarmee de prooien gegrepen worden. De tong is echter niet lang en dun, maar juist kort en zeer breed en zit opgevouwen in de bek. Als de tong naar buiten komt, ontvouwt deze zich en plooit zich om het prooidier. Vervolgens trekt de tong zich terug en beweegt de salamander zijn de kop naar voren om toe te happen. Als het dier bedreigd wordt, wuift hij met de staart om belagers af te schrikken. De kleur is vaak al afschrikwekkend. In feite is het dier ongevaarlijk, ondanks dat ze veel gelijkenis vertonen met de giftige jongen van de groene watersalamander (Notophthalmus viridescens).
Een legsel bestaat meestal uit ongeveer 70 eieren, die worden vastgehecht aan de onderkant van stukken hout of stenen, soms onder water.
De rode salamander komt voor in het oosten van de Verenigde Staten en leeft in poelen en vennen in heidevelden, bossen en graslanden. Deze soort is sterk aan water gebonden maar jaagt ook wel op het land.

Röd salamander (Pseudotriton ruber) är ett stjärtgroddjur i familjen lunglösa salamandrar, som finns i östra USA.
Den röda salamandern har en klart orangeröd till purpurbrun färg på ovansidan och sidorna, de ljusare tonerna främst hos unga individer. Grundfärgen är beströdd med mörka fläckar. Kroppsformen är kraftig, med en längd på mellan 10 och 18 cm.[3] [4]
Den röda salamandern finns i östra USA från södra New York till södra Indiana i norr, och söderut till västkusten söder om Virginia samt sydkusten (med undantag av halvödelen av Florida).[2]
Den röda salamandern delas in i underarterna Pseudotriton ruber ruber, P. r. nitidus, P. r. schencki och P. r. vioscai.[5]
Salamandern vistas både på land och i vatten. Generellt föredrar den långsamt rinnande vatten som källor och bäckar i trädbevuxna områden, även om den tillfälligtvis kan påträffas i mera strömt vatten, och på den omgivande marken. På land gömmer den sig gärna under stenar, kvistar och i mossa i trädklädda dalgångar, ängar och fält, gärna fuktiga sådana. Salamandern kan bli över 20 år gammal.[6]
Födan består av andra, mindre salamandrar, insekter som bland annat skalbaggar och syrsor, gråsuggor, spindlar, mångfotingar och sniglar. Larverna äter mindre, akvatiska ryggradslösa djur.[6] Liksom många stjärtlösa groddjur har den en klibbig tunga som den kan slänga ut för att fånga byten med. Själv utgör den föda åt flera fågelarter, skunkar och tvättbjörnar.[3] Som försvar har den en giftig hudavsöndring (pseudotritotoxin) som verkar avskräckande på flera predatorer.[4]
Fortplantning och larvutveckling sker i vatten. Parningsleken äger rum från våren till hösten; under denna gnider hanen sin nos mot honans huvud och haka, och hon svarar genom att gnida sin haka mot hanens svans när han simmar framåt. Till slut avsätter hanen en spermatofor som honan tar upp med sin kloak. Honan kan lagra sperman och lägger vanligtvis mellan 30 och 130 ägg under hösten, ibland flera månader efter parningen. Äggen fästs på undersidan av klippor och stenar i samma vatten som den vuxna salamandern brukar vistas i. De kläcks tidigt på vintern, och larven förvandlas efter 2 till 3 år, under sommaren.[3] Hanarna blir könsmogna vid omkring 4 års ålder, honorna ett år senare.[6]
Röd salamander betraktas som livskraftig ("LC"). Även om beståndet minskar något, anses det inte vara någon fara på sikt. Vattenföroreningar, speciellt surt spill från kolgruvor, kan dock utgöra lokala hot.[2]
Röd salamander (Pseudotriton ruber) är ett stjärtgroddjur i familjen lunglösa salamandrar, som finns i östra USA.
Загальна довжина досягає 9—18 см за своєю будовою й забарвленням схожа на мулову саламандру. Відрізняється загостреною мордою, більшими плямами на спині та помаранчево-жовтими очима.
Полюбляє чагарники, кущі біля гірських водойм. зустрічається на висоті до 1500 м над рівнем моря. Взимку перебуває у холодних струмках, влітку пересувається суходолом. Активна у присмерку. Живиться великими безхребетними.
Статева зрілість настає у 5 років. Шлюбний сезон відбувається в восени та взимку. Самиця відкладає під каміння 50—100 яєць. за сезон буває декілька кладок.
Мешкає у східних штатах США.
