Amphibians
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...

Gray Tree Frog
The gray treefrog (''Dryophytes versicolor'') is a species of small arboreal holarctic tree frog native to much of the eastern United States and southeastern Canada. It is sometimes referred to as the eastern gray treefrog, northern gray treefrog, common gray treefrog, or tetraploid gray treefrog to distinguish it from its more southern, genetically disparate relative, Cope's gray treefrog. Description As the scientific name implies, gray treefrogs are variable in color. This ability to vary their color provides them with the ability to camouflage themselves from gray to green or brown, depending on the environment around them. ''H. versicolor'' can change from nearly black to nearly white. They change color at a slower rate than a chameleon. A unique aspect of the appearance of gray treefrogs is that its legs feature a dark band-like pattern which then contrast sharply with the black-marked bright yellow or orange under the sides of its legs and arms. Dead gray treefrogs and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-lined Salamander
The three-lined salamander (''Eurycea guttolineata'') is a species of salamander in the family Plethodontidae. It is endemic to the south-eastern United States. Like other Plethodontidae species, ''E. guttolineata'' captures prey via tongue projection. Description ''Eurycea guttolineata'' is a mid-sized, slender stream salamander which ranges from about 10-15.9 cm in its adult form. It is tan to light yellow with three black longitudinal stripes running from the eyes down the length of the body to the tail. The tail is very long at approximately two-thirds its total body length. Additionally, the ventrum (belly) of the three-lined salamander is boldly marked with black and white marbling. Reproduction Hatchlings are generally around 10-13 mm and undergo metamorphosis when they are 22-27 mm snout-to-vent length. This is typically a 4-6 month larval stage. The effects that elevation has on larval stages have been studied extensively showing that at lower elevations larvae me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Two-lined Salamander
The northern two-lined salamander (''Eurycea bislineata'') is a species of salamander in the family Plethodontidae found in Canada and the United States. Its natural habitats are temperate forests, temperate shrubland, rivers, intermittent rivers, freshwater marshes, freshwater springs, arable land, and urban areas. It is more water-oriented than the related northern redback salamander, and can often be found in and around water such as rain puddles, streams, swamps, and damp stream beds, whereas the northern redback tends to be found in damp ground, but usually not near open water. Description The northern two-lined salamander is a small salamander, with adults ranging from 65–120 mm in total length.Petranka, J.W. (1998). Salamanders of the United States and Canada. Smithsonian Institution Press. pp. 587. This salamander is yellow or yellowish-brown, with two black stripes running down the back which tends to break up after the base of the tail. The flanks are mottled gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desmognathus Mo
''Desmognathus'' is a genus of lungless salamanders in the family Plethodontidae known as dusky salamanders. They range from Texas to the eastern United States and to south-eastern Canada. Characteristics Species of the genus ''Desmognathus'' have a unique jaw-opening mechanism where the lower jaw is stationary and the skull swings open. There are additional stalked condyles, an atlanto-mandibular ligament, along with other skeletal and musculature features that have evolved to accompany this type of jaw-opening mechanism. Additionally, they are known to exhibit maternal care by brooding over their eggs. Species This genus includes the following 30-31 species: References External links Tree of Life: Desmognathus* Further reading * Baird SF. 1850.

Seal Salamander
The seal salamander (''Desmognathus monticola'') is a species of lungless salamander that is endemic to the Eastern United States. Distribution and habitat The seal salamander can be found from southwestern Pennsylvania and south through Appalachian Mountains areas of high elevation in West Virginia, western Maryland, western and northern Virginia, eastern Kentucky, western North Carolina, eastern Tennessee, western South Carolina, and northern Georgia to central Alabama. There are also disjunctive populations in southern Alabama as well as at the very western end of the Florida panhandle. In the north of its range, it has not been observed north or west of the Ohio River. An introduced population is present in Benton County, Arkansas. Its habitat includes rocky mountain streams, spring-fed brooks in the ravines of deciduous forests, muddy sections of streams and seepages. The total adult population size of the species is assumed to exceed 100,000. Etymology The genus name ''D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Dusky Salamander
''Desmognathus fuscus'' is a species of amphibian in the family Plethodontidae ( lungless salamanders). The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form several distinct species, the southern dusky salamanders ('' D. auriculatus, D. valentinei''). The northern dusky salamander is the most widespread representative of its genus in Canada. It can be found in eastern North America from extreme eastern Canada in New Brunswick south to South Carolina. The size of the species' total population is unknown, but is assumed to easily exceed 100,000. The species' habitat differs somewhat geographically; dusky salamanders in the northern part of the range prefer rocky woodland streams, seepages, and springs, while those in the south favor floodplains, sloughs, and muddy places along upland streams. They are most common where water is running or trickling. They hide under various object ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Pseudacris Feriarum
The upland chorus frog (''Pseudacris feriarum'') is a species of chorus frog found in the United States.
