After posting the photos of the Fowler's Toad (click here for that post), I had a lot of emails from readers asking how to tell a toad and frog apart, so I thought I'd put something together quickly to explain. Let's start with two frogs I recently photographed while I was up at Magee Marsh for the Biggest Week in American Birding. After you see a couple of frogs, we'll move on to telling frogs and toads apart. The first frog is a Green Frog... Female Green Frog (Rana clamitans melanota) The easiest way to identify a Green Frog is to study the length of the dorso-lateral fold. Notice the fold of skin that starts just behind the eye, goes over the tympanum (ear drum disc behind the eye) and runs the length of the body. This ridge is the lateral fold. On Green Frogs, it runs the length of the body. Green Frogs (Rana clamitans melanota) and Bullfrogs (Rana catesbeiana) are both green, and a small Bullfrog can look a lot like a Green Frog, but if you look at the lateral fold, there is no mistaking the two. On a Bullfrog, the dorso-lateral fold curls around the tympanum.... Male Bullfrog (Rana catesbeiana) Notice how the lateral fold curls around the tympanum (eardrum disc next to the eye) and does not extend down the length of the back. Young Bullfrogs can resemble Green Frogs; however, as soon as you check out the lateral fold, you'll know which frog is which! Telling a male frog from a female frog There is an easy trick for determining the sex of a Green Frog and a Bullfrog. Look at the tympanum behind the eye. Female tympanums are about the same size as the eye. Male's are almost twice as big! Note: This little trick works only for Green Frogs and Bullfrogs. The tympanum on most other frogs and toads is slightly smaller than the eye. To determine the sex of a Green Frog or a Bullfrog compare the tympanum (ear drum) to the eye. A female's tympanum is about the same size as the eye; a male's is almost twice as large! I wish this trick worked for all frogs and toads! (Pencil sketch from my sketchbook.) What are the differences between a frog and a toad? Scientifically, there really is no difference between a frog and a toad--both are amphibians in the order "Anura." Morphologically, however, you can see physical differences between the two, and because of that, scientists have classified them into different families. The following characteristics separate "true frogs" (family Ranidae) from "true toads" (family Bufonidae)... Skin Frogs usually have wet and smooth skin because they rarely leave the water. Toads usually have dry and bumpy or warty skin because they prefer to live in damp locations away from the water. Legs Frogs have long legs and feet, and they can jump far. Toads have shorter legs and can hop, but they can't jump that far. Toads tend to walk around or make little hops. Parotoid gland Some frogs are poisonous to the touch, but only toads have the large parotoid gland behind the eyes that secretes a toxin that can burn the mouth and mucous membranes of a predator. Body shape Frogs tend to be leaner and more streamlined for swimming. Toads are often described as being "chubby" or squat. Eggs Frogs usually lay eggs in clusters or mats. Toads tend to lay eggs in chains. Eyes Frogs are said to have more prominent or "buggy" eyes. Toads less so (for me, the bugginess of the eyes is harder to distinguish. They all look pretty buggy to me!). The differences between a frog and a toad become apparent when you place them side by side. Toads definitely look chubbier, but the Parotoid gland is what really separates them for me. When I see that poison pouch, I know I'm looking at a toad, and if I see a lateral fold, I know I'm looking at a frog. (Pencil sketch from my sketchbook.) These characteristics are generalities and blur quickly when you look at all the Anura families. For example, a Blanchard's Cricket Frog looks a little toady at first glance. He's bumpy and muddy looking and can be found away from water, but if you look for a Parotoid gland you won't find one, because he's a frog...not a toad. (Click here for a post on Cricket Frogs.

In Ohio, you can find the following Anuran families: Ranidae ("true frogs") - Bullfrog, Green Frog, Leopard Frog, Pickerel Frog, Wood Frog Hylidae - Gray Treefrogs, Chrous Frogs, Spring Peeper, and Cricket Frog Bufonidae ("true toads") - American Toad, Fowler's Toad Scaphiopodidae - Eastern Spadefoot Toad For a complete list of Anuran families, click here.
