The American toad (Bufo americanus) is a common species of toad found throughout the eastern United States and Canada. It is divided into three subspecies—the eastern American toad (B. a. americanus), the dwarf American toad (B. a. charlesmithi), and the rare Hudson Bay toad (B. a. copei). A new taxonomy considers this species Anaxyrus americanus. less ↑

The American bullfrog (Lithobates catesbeianus), often simply known as the bullfrog in Canada and the United States, is an aquatic frog, a member of the family Ranidae, or “true frogs”. This species has traditionally been classified as Rana catesbeiana, however the classification has been changed to Lithobates due to paraphyly in Ranidae. This frog has an olive green back and sides blotched with brownish markings and a whitish belly spotted with yellow or grey. The upper... less ↑

The wood frog (Lithobates sylvaticus) has a broad distribution over North America, extending from the southern Appalachians to the boreal forest with several notable disjunct populations including lowland eastern North Carolina. The wood frog has garnered attention by biologists over the last century because of its freeze tolerance, relatively great degree of terrestrialism (for a Ranid), interesting habitat associations (peat bogs, vernal pools, uplands), and relatively long-range movements. The ecology and conservation of the wood frog... less ↑

Desmognathus fuscus is an amphibian in the lungless salamander family. The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form a separate species, the southern dusky salamander (D. auriculatus). It can be found in eastern North America from extreme eastern Canada in New Brunswick south into the panhandle of Florida and west to Louisiana. The size of the species' total population is... less ↑

The spring salamander (Gyrinophilus porphyriticus) is a species of salamander in the family Plethodontidae. The specific name is Latin from Greek, meaning the color of porphyry, a purple stone, and this salamander has also been called the purple salamander. It is found in Canada and the United States. Its natural habitats are temperate forests, rivers, swamps, freshwater marshes, freshwater springs, inland karsts, and caves. Although deforestation is a potential threat, it occurs in many protected areas... less ↑

The northern two-lined salamander (Eurycea bislineata) is a species of salamander in the Plethodontidae family 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... less ↑

The red back (or redback or red-backed) salamander (Plethodon cinereus) is a small, hardy woodland salamander. It inhabits wooded slopes in eastern North America, west to Missouri, south to North Carolina, and north from southern Quebec and the Maritime Provinces in Canada to Minnesota. It is also known as the eastern red-backed salamander or the northern red back salamander to distinguish it from the southern red back salamander (Plethodon serratus). less ↑

The eastern newt (Notophthalmus viridescens) is a common newt of eastern North America. They frequent small lakes, ponds, and streams or near-by wet forests. They can coexist in an aquatic environment with small, noncarnivorous fish, as their skin secretes a poisonous substance when the newt is threatened or injured. They have lifespans of 12 to 15 years in the wild, and may grow to five inches in length. These newts are common aquarium pets, being either... less ↑

The northern slimy salamander, Plethodon glutinosus, is a species of terrestrial plethodontid salamander found through much of the eastern two-thirds of the United States, from New York, west to Illinois, south to Texas, and east to Florida, with isolated populations in southern New Hampshire and northwestern Connecticut. It is called "slimy" because it is capable of excreting a sticky, glue-like substance from its skin. It is also sometimes referred to as the viscid salamander, grey-spotted salamander,... less ↑

The common mudpuppy (Necturus maculosus) is a species of salamander in the genus Necturus. They live an entirely aquatic lifestyle in the eastern part of North America in lakes, rivers, and ponds. Mudpuppies go through paedomorphosis and retain their external gills. Because skin and lung respiration alone is not sufficient for gas exchange, mudpuppies must rely on external gills as their primary means of gas exchange. Mudpuppies are usually a rusty brown color and can grow... less ↑
