Rana catesbeiana

Bullfrog

Identification/Variations: A large introduced frog that is typically greenish brown with brown blotches. They reach over 7 inches in length making them the largest frog in the Pacific Northwest. Males have a very large tympanum (frog ear) and you can see with difference between the male on the left compared to the females on the right. There are no recognized variations of this frog.

Range/Habitat: Enjoys lowland sloughs and ponds. This frog is often seen peering out from underneath lily pads. Only young Bullfrogs are regularly observed out of the water. Even they will not stray far and are only a hop or two away from the waters edge. Bullfrogs are found throughout the Pacific Northwest except for high elevations in the Cascade and Olympic Mountains in Oregon and Washington. In British Columbia they are mercifully only found in the southwest corner of the provence.

Notes: This non-native frog will eat absolutely anything including turtles, snakes, ducks, and even other Bullfrogs. When I was younger I had two pet Bullfrogs of the same size that both died when one tried to eat the other.
