Lithobates clamitans

The green frog (Lithobates clamitans[4] or Rana clamitans[1][5][6]) is a species of frog native to the eastern half of the United States and Canada. The two subspecies are the bronze frog and the northern green frog.

Description 

This species is a mid-sized true frog. Adult green frogs range from 5–10 cm (2.0–3.9 in) in body length (snout to vent, excluding the hind legs).

Lithobates pipiens

The northern leopard frog (Lithobates pipiens[1][2][3][4] or Rana pipiens[5][6]) is a species of leopard frog from the true frog family, native to parts of Canada and United States. It is the state amphibian of Minnesota and Vermont

Description 

Young northern leopard frog

The northern leopard frog is a fairly large species of frog, reaching about 11 cm (4.3 in) in snout to vent length (SVL).

Anaxyrus americanus

The American toad (Anaxyrus americanus, formerly Bufo americanus[2]) is a common species of toad found throughout the eastern United States and Canada. It is divided into three subspecies—the eastern American toad (A. a. americanus), the dwarf American toad (A. a. charlesmithi), and the rare Hudson Bay toad (A. a. copei). Recent taxonomic treatments place this species in the genus Anaxyrus instead of Bufo

Hyla versicolor

The gray treefrog (Hyla versicolor) is a species of small arboreal frog native to much of the eastern United States and southeastern Canada.[2]

It is sometimes referred to as the eastern gray treefrog, common gray treefrog, or tetraploid gray treefrog to distinguish it from its more southern, genetically disparate relative, the Cope's gray treefrog (Hyla chrysoscelis). It may sometimes be referred to as the North American treefrog by Europeans to distinguish it from their European treefrog (Hyla arborea)

Description 

As the scientific name implies, gray treefrogs are variable in color owing to their ability to camouflage themselves from gray to green, depending on the substrate where they are sitting. The degree of mottling varies.[3] They can change from nearly black to nearly white.

Plethodon cinereus

The red-backed (or redback[2]) 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[2] or the northern red-backed salamander to distinguish it from the southern red-backed salamander (Plethodon serratus). It is one of 55 species in the genus Plethodon.

Lithobates sylvaticus

The wood frog (Lithobates sylvaticus or Rana sylvatica[2]) 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 has attracted research attention in recent years because they are often considered "obligate" breeders in ephemeral wetlands (sometimes called "vernal pools") that are themselves more imperiled than the species that breed in them. The wood frog has been proposed to be the official state amphibian of New York.
