Illinois Chorus Frog
Tan to tannish-gray with a white belly and many dark brown or gray irregularly-shaped markings on its body. This frog has a distinguished "V"-shaped marking between the eyes, a dark stripe from snout to shoulder, and a dark spot below each eye. Young froglets are dull gray and have inconspicuous body markings.
The skin of the Illinois chorus frog has a rough texture. The large and muscular forearms of this frog are used to dig the burrows where it spends much of the year. The webbing on the hind feet is poorly developed.
