| The Pacific Treefrog is the most commonly heard frog on the west coast. The color of the individual can vary. They are most often a green or a gray, but may also be brown or black. Within the same individual it may change colors within only a few minutes from one color to another. They usually have some dorsal markings as shown in the upper right photo, but the photo to the right shows that there are exceptions. One thing that goes without exception, however, is the dark band running through the eye towards the front limb and the white underbelly. They are a small treefrog attaining lengths up to 2 inches. The voice of this frog is known around the world - the "ribbit" that Hollywood uses in all of its films as the "standard" frog call is actually the call of the Pacific Treefrog! |

| Although this species is called a treefrog, it has been found to be more closely related to the Chorus Frogs of genus Pseudacris. Below are more photos of the Pacific Treefrog. |
