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.
Plethodon is part of the family Plethodontidae (lungless salamanders) and the subfamily Plethodontinae.The genus Plethodon can be divided into two subgenera: the nominal subgenus Plethodon, which includes up to 49 eastern species (the bulk of diversity in the genus), and the subgenus Hightonia, [5] which includes 9 species native to the western part of North America.

The long-toed salamander (Ambystoma macrodactylum, Baird 1849) [3] is a mole salamander in the family Ambystomatidae. This species, typically 4.1–8.9 cm ( 1 + 3 ⁄ 5 – 3 + 1 ⁄ 2 in) long when mature, is characterized by its mottled black, brown and yellow pigmentation, and its long outer fourth toe on the hind limbs.

Hydromantes, commonly referred to as web-toed salamanders, is a genus of the lungless salamander family, Plethodontidae; they achieve respiration through their skin and the tissues lining their mouth. They are endemic to mountains of California in the United States. [1]
The tail drops off and wriggles around for a while after an attack, and the salamander either runs away or stays still enough not to be noticed while the predator is distracted. The tail regrows with time, and salamanders routinely regenerate other complex tissues, including the lens or retina of the eye. Within only a few weeks of losing a ...
