eschescholtzii - named for the scientist who first described the species
A constriction at the base of the tail causes its tail to fall off when it is grabbed by a predator. Originally, this species was thought to consist of several subspecies, but more recently has been described as a "super species" consisting of eleven genetically diverged groups. Currently, the taxonomy of the Ensatina eschescholtzii complex is under debate. In Canada, there is only one group present. Despite its common name, this salamander lives not only in Oregon, but all along the Pacific Coast.
