The Eastern Narrow-mouthed Frog is one of the smallest Kentucky frogs. A huge one may reach 1 1/2 inches, but most are smaller. An Eastern Narrowmouth has a round chubby body, very short stubby legs, and a pointy little head set off by a fold of skin across the nape of the neck. These frogs can be gray, brown, or reddish-brown above, darker along the sides, with or without a sizeable dark outline in the center of the back.

These curious little frogs can be found across southern and western Kentucky in a variety of habitats ranging from mature forests to overgrazed pastures, rocky glades​, abandoned quarries, gravel pits, and surface mines. They call and breed from late May through early August in wet grassy meadows, roadside ditches, and small ponds. Narrow-mouthed Frogs will often call by day just after a summer rain. Males hide under the grass and are very hard to find when calling; the voice is an angry buzzing bleat and sounds like the call of an undersized Fowler's Toad.
