Columbia Spotted Frog (Lithobates luteiventris)

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.

Wood Frog (Lithobates Sylvaticus)

The Wood Frog is highly adaptable to the cold, they can even freeze completely solid.

Northern Red-legged Frog (Rana aurora)

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.

Tree Frog Family – Hylidae

Pacific Chorus Frog

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.
