[edit] Description
The Oregon spotted frog reaches a length of 4 centimetres (1.6 in) to 10 centimetres (3.9 in). Females are slightly larger than males. These frogs range in color from green to reddish-brown and have black spots on the head and back. Rana pretiosa is identifiable by the reddish or salmon on sides and venter and eyes slightly upturned. Its diet is flies and small fish.[2]
[edit] Distribution
Oregon Spotted Frogs are found in British Columbia, Washington State and Oregon. They were previously found but have been extirpated in California.[3]
In Oregon, the Oregon spotted frog's current range is Deschutes, Lane and Klamath counties.[4]
