I nearly stepped on this big guy last night while walking in the yard. (He was about 10-12 inches long if you stretched his legs out.) I see toads all the time - two of them live in the gardens - but this is only the second time in my life I've seen a frog. Romie says it's a bullfrog, and we've been hearing one every night for quite awhile now. Our neighbors have a pond, so it's a familiar summer sound and I love hearing it.
The way to tell a bullfrog from a green frog is that the green frog has ridges that go all the way down its back from its eyes. The bullfrog doesn't have these. And you can tell male from female by looking at their eardrums. The female's eardrums are the size of its eyes. The male's are smaller. Since our bullfrog's eardrums are even bigger than its eyes, I think it must be a female.
The American Bullfrog is the largest frog in North America. It's a nocturnal amphibian that comes out of hibernation in April and stays active until October. The average lifepan of a bullfrog is seven to nine years.
