Southern two-lined salamander
The southern two-lined salamander (''Eurycea cirrigera'') is a species of salamander in the family Plethodontidae, endemic to the United States. Its natural habitats are temperate forests, rivers, intermittent rivers, swamps, and freshwater springs.
==Appearance==
The Southern two-line salamander is a small thin salamander, distinguished by the two lines running down the lateral portion of its body. The salamander is deep-light brown and fairly small, growing up to 6.5–12 cm in length. The key difference between the Southern two lined salamander from the Northern salamander is that the black lines run all the way down to the tail. When the salamander reaches sexual maturity males begin to show Cirri and enlarged jaw muscles.
The Southern two-line salamander had two morphs, one of these, the Brownback salamander is now its own species. The other morphs, the Cole Springs Phenotype is found in other two lined salamanders but in the Southern two-lined salamander is limited to northern Alabama. This morphs results in an individual being significantly larger and darker colored than the normal salamander.〔Nelson, N. "Eurycea facts." Caudta Cultur. N.p., Dec. 2003. Web. 21 Apr. 2014. .〕
