Image of California Red-legged Frog

Description:

I am failry sure this is a male CA Red-legged Frog (Rana draytonii) in aplexus with a female bullfrog (Rana catesbeiana). Maybe not quite as cool as cross-order confusion, but still odd. I wonder if there are conservation implications for the red-legged, which is threatened by habitat destruction in some parts of the state. Would there be any noticeable impact of males wasting their time on females of another species?
