critter_bob;4228959; said:One good way to tell the difference between bullfrogs and green frogs is the dorsolateral grove (the "ridge" that goes from the eye area down towards the leg).
On green frogs, the ridge goes all the way from the head to the hind legs, while on bullfrogs, the ridge does not. I didn't see any clear side view photos of the ID frog, but it looked like it could very well just be a green frog with different color than normal. Can you look at the ridge, and describe it?
