The spotted salamander is about 15–25 cm (5.9–9.8 in) long (tail included), [7]: 76 with females generally being larger than males. [8] It is stout, like most mole salamanders, and has a wide snout. [3] The spotted salamander's main color is black, but can sometimes be a bluish-black, dark gray, dark green, or even dark brown.
The reason it is referred to as a big night is because there is a large number of salamanders moving at the same time. Warmer air and loose soil coupled with rain cause salamanders to leave their underground burrows. The event takes place at night to minimize predation. The rain on the big night keeps the salamanders skin from becoming dry. [1]
A correlation exists between the toxicity of Californian salamander species and diurnal habits: relatively harmless species like the California slender salamander (Batrachoseps attenuatus) are nocturnal and are eaten by snakes, while the California newt has many large poison glands in its skin, is diurnal, and is avoided by snakes.

The red-backed salamander is a small terrestrial salamander, 5.7–10.0 cm (2.2–3.9 in) in total length (including tail), which usually lives in forested areas under rocks, logs, bark, and other debris. [4] It is one of the most numerous salamanders throughout its range. [4] As with all amphibians, the red-backed salamander has permeable skin.
The green salamander (Aneides aeneus) is a species of lungless salamander in the family Plethodontidae. [2] It and the Hickory Nut Gorge green salamander (A. caryaensis) are the only currently-described members of the genus Aneides that inhabit any areas in the eastern half of United States (all other Aneides salamanders are found west of the Mississippi River).
Desmognathus fuscus is a species of amphibian in the family Plethodontidae (lungless salamanders). [2] [3] 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). [3]
Axolotls may be confused with the larval stage of the closely related tiger salamander (A. tigrinum), which are widespread in much of North America and occasionally become paedomorphic, or with mudpuppies (Necturus spp.), fully aquatic salamanders from a different family that are not closely related to the axolotl but bear a superficial ...
The reticulated flatwoods salamander (Ambystoma bishopi) is a species of mole salamander, an amphibian in the family Ambystomatidae. [3] The species is native to a small portion of the southeastern coastal plain of the United States in the western panhandle of Florida and extreme southwestern Georgia .
