Description
Size
Adult Ensatina measure from 1 1/2 - 3 1/5 inches long ( 3.8 - 8.1 cm) from snout to vent, and 3 - 6 inches (7.5 - 15.5 cm) in total length. The Painted Ensatina subspecies is smaller than other Ensatina subspecies - averaging about 2/3 their size.
Appearance
A medium-sized plethodontid salamander which breathes through its smooth moist thin skin. The legs are long, and the body is relatively short, with 12 - 13 costal grooves. Nasolabial grooves are present. The tail is rounded and constricted at the base, which will differentiate this salamander from its neighbors. Males have longer, more slender tails than females, and a shorter snout with an enlarged upper lip.

This subspecies is dark tan to brown above, with dark blotching along the upper sides, and yellow to orange blotching on the lower sides. The underside is pale orange or pinkish and the tail is mottled with black and yellow.
Behavior
Ensatinas live in relatively cool moist places on land, and stay underground during hot and dry periods where they are able to tolerate considerable dehydration. They are most active on rainy or wet nights when temperatures are moderate. High-altitude populations are also inactive during severe winter weather. When disturbed, this salamander will stand tall in a stiff-legged defensive posture with its back swayed and the tail raised up. Often the salamander will secrete a milky white substance from the tail. This noxious substance repels potential predators.
Diet
Eats a wide variety of invertebrates. Click here to watch a movie of an Ensatina feeding.
Reproduction
Breeds mainly in fall and spring, but may also breed throughout the winter. Females lay eggs on land, brooding them under bark or in rotting logs or underground. The young hatch fully formed.
Range
The Painted Ensatina subspecies occurs in a small range along the Pacific coast from extreme northwest California in Del Norte County, to extreme southwest Oregon in Curry County.

The species Ensatina is found in an isolated location in the mountains of Baja California and along the extreme northwest coast of Baja California, north through California circling the central valley, in the Cascades Mountains and west of the mountains in Oregon and Washington, on Vancouver Island, and along the coast of southern British Columbia.
Habitat
Inhabits moist shaded evergreen and deciduous forests. Found under rocks, logs, other debris, especially bark that has peeled off and fallen alongside logs and trees. Most common where there is a lot of coarse woody debris on the forest foor. In dry or very cold weather, stays inside moist logs, animal burrows, under roots, woodrat nests, under rocks.
Taxonomic Notes
Robert Stebbins eliminated the range of the subspecies E. e. oregonensis (which he calls a "morphotype" not a subspecies) in California, showing a very large area of intergradation in California between E. e.picta and E. e. xanthoptica and E. e.picta and E.e. platensis. (Stebbins 2003)

Ensatina eschscholtzii is typically treated as a "ring" species, consisting of 7 subspecies: E. e. croceater, E. e. eschscholtzii, E. e. klauberi, E. e. oregonensis, E. e. picta, E. e. platensis, and E. e. xanthoptica, which ring the Central Valley, but do not interbreed where the rings overlap in Southern California (and possibly in the central Sierra Nevada.) Some researchers see Ensatina eschscholtzii as two or more species forming a superspecies complex, recognizing E. e. klauberi, found at the southern end of the ring, as a separate species - Ensatina klauberi.
