I saw this Ensatina just after dusk near Redwood Camp at Landels-Hill Big Creek. It had to be a recently emerged juvenile because it was extremely small compared to other Ensatinas I have seen.
Ensatina eschscholtzii (commonly known by its genus name, Ensatina) is a complex of plethodontid (lungless) salamanders found in coniferous forests, oak woodland and chaparral from British Columbia, through Washington, Oregon, across California (where all seven subspecies variations are located), all the way down to Baja California in Mexico.
