Ensatina
''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. The genus Ensatina originated approximately 21.5 million years ago.
==Habitat and description==
The Ensatina subspecies ''E. e. eschscholtzii'', or Monterey Ensatina, can be found in Santa Cruz, Monterey, and the California coastal mountains. They reach a total length of three to five inches, and can be identified primarily by the structure of the tail, and how it is narrower at the base. This salamander is the only type that has this tail structure and five toes on the back feet.
Males often have longer tails than the females, and many of the salamanders have lighter colored limbs in comparison to the rest of the body. The salamanders lay their eggs underground, often in threes, which then hatch directly into salamanders, skipping the usual aquatic phase.
