Washington is home to 27 species of amphibians, including 14 salamanders (all native) and 11 native and 2 non-native frogs. Two species of salamanders occur only in Washington and nowhere else in the world! Many of the other local amphibians are unique to the Pacific Northwest. In fact, three entire families of amphibians (Dicamptodontidae, Rhyacotritonidae, and Ascaphidae) are endemic to the Pacific Northwest (that is, the entire family is found only in the Northwest); all of the amphibian species in these three endemic families are specialized for life in the clear, cool streams of Pacific Northwest forests.

We invite you to explore the diversity of northwestern amphibians as shown below in our checklist. You can see pictures and learn more about many of these species by clicking on the links below. Photographs and information about more species will be added soon, so check back regularly!
