In early spring the females nest on land, along the banks of small ponds. After the 4–6 week embryonic period, the larvae hatch and make their way to the adjacent pond. Four-toed salamanders undergo a relatively short aquatic larval period, when compared to other species of the same family, ranging between 3 and 6 weeks. [3] [4] [6]
Plethodontidae, or lungless salamanders, are a family of salamanders. [ 1 ] [ 2 ] With over 500 species, lungless salamanders are by far the largest family of salamanders in terms of their diversity. Most species are native to the Western Hemisphere , from British Columbia to Brazil.
Many species within this group (including the nominal species) are commonly known as "slimy salamanders", characterized by a large size, robust build and black-and-white coloration. Not all members of the Plethodon glutinosus group are labelled as slimy salamanders, and species delimitation among slimy salamanders and their close relatives is a ...

[6] [7] The spotted dusky salamander (D. conanti) and the flat-headed salamander (D. planiceps) were described in the 1950s but were later thought to be synonymous with the northern dusky salamander, but further studies have ...
