  • Are only found in Washington State in the Olympic Mountains, southern Cascade Mountains and Willapa Hills area.

Breeding

  • Female guards the eggs until hatching.
  • Do not have an aquatic larval stage; they hatch straight into small fully formed salamanders.

Cool Biology Facts

  • The color differences might be associated to different levels of elevation and temperature.
  • Live in scattered isolated populations.
