The bullfrog is Missouri’s largest frog; it ranges from green to olive to brown. The back may have small brown spots or dark, indistinct, irregular blotches. The hind legs are marked with distinct dark brown bars. The belly is white, and the throat may have some gray mottling. The external eardrum is large and round. On adult males this tympanum is much larger than the eye; on females, it’s about the same size as the eye. This species has been known to reach 8 inches from snout to vent. Call is a deep, sonorous “jug-a-rum, jug-a-rum” that can be heard from half a mile away or more.
