No official source we use states whether this animal is venomous. That does not mean it is harmless: do not handle it.
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.

Green Treefrog or Gray Treefrog and Cope's Gray Treefrog?
Missouri Department of Conservation calls both gray treefrogs gray, unlike the green treefrog, but its gray treefrog account says their color may be green to light greenish gray, gray, brown or dark brown, so color alone does not settle it. MDC: gray treefrogs have warty (granular) skin; the green treefrog's back is smooth and a light stripe runs from its upper lip down the side of the body.
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.
Photos show typical adults; individuals vary. Never get close to compare.
