No official source we use states whether this animal is venomous. That does not mean it is harmless: do not handle it.
Size
Usually 6 to 8 inches long (NCWRC); can reach 8 inches or more and weigh over 2 pounds (CDFW). Missouri gives 3.5 to 6 inches snout to vent, occasionally to 8.75.
How to recognize it
No ridge (dorsolateral fold) down each side of the back
Large round eardrum: about twice the eye in males, about eye-sized in females
Fully webbed hind feet, longest toe extends past the webbing

Size
2 to 3.5 inches long (NCWRC: up to 4 inches); females are larger than males.
How to recognize it
Dark spots on the back hold only a few large warts; the similar Fowler's toad has three or more. Agencies give different counts for the American toad (TWRA: one or two; Ohio DNR: one, two or three; Georgia DNR: usually no more than one), so wart count alone does not settle it; check the head crests too (see lookalikes).
A large, kidney- or bean-shaped parotoid gland behind each eye that usually does not touch the bony ridge (cranial crest) above the eye, or touches it only by a short spur.
The difference official sources agree on is at the head: in the American toad the ridge (cranial crest) behind each eye is separate from the parotoid gland or joined to it only by a short spur; in Fowler's toad the two touch. Fowler's toad also has three or more warts in each of the larger dark spots, while the American toad has fewer (TWRA: one or two; Ohio DNR: one, two or three; Georgia DNR: usually no more than one). Fowler's toad has a whitish belly, often with a single dark spot on the chest; the American toad's belly is peppered with dark spots. The two can hybridize, so some toads cannot be told apart.

Maine IF&W lists the spring peeper's distinguishing characteristics: Maine's smallest frog (about 0.8 to 1.5 inches), grayish- or orangish-brown above with a distinct dark X on the back, and smooth skin; it notes it is commonly confused with the gray treefrog.
Green frog (young; including bronze color form) Not stated
MDC: young green frogs can be similar in color but lack the dark brown mask through each eye.
Photos show typical adults; individuals vary. Never get close to compare.
