Frogs of Alaska
True Frogs – Ranidae
Alaska has only three true frog species and they are relatively easy to tell apart. These frogs are generally found near or in bodies of water.
Common Name: Columbia Spotted Frog
Scientific Name: Rana luteiventris
Location: Southeast
Breeding Season: After the snow melts
The Columbia Spotted Frog is lighter in color than the other true frogs in the state. It has tiny dots that are black but hollow. Its legs are yellow on the underside.
Common Name: Wood Frog
Scientific Name: Rana sylvatica
Location: Southern Alaska up to Central Alaska
Breeding Season: After the snow melts
The Wood Frog is highly adaptable to the cold, they can even freeze completely solid.
Toads of Alaska
True Toad Family – Bufonidae
Alaska only has one toad species, the Western Toad (Anaxyrus boreas).

Non-Native / Invasive Species of Alaska

Scientific Name: Rana aurora
Location: Chichagof Island

The Northern Red-legged Frog is actually an invasive species in the state of Alaska. They were introduced in the 1980s. To separate them from Wood Frogs, just look for the red underneath their legs.

The Pacific Chorus Frog is the only tree frog in the state of Alaska. They are not actually native to the state, they were accidentally brought into the state by Christmas trees.
