Lowland Leopard Frog vs. American Bullfrog

Bullfrogs were brought into Arizona's stock tanks, canals and rivers and now share almost every water the native leopard frogs live in (and eat them); young bullfrogs are often taken for leopard frogs. A: A ridge down each side of the back, broken and turned inward near the hips in the Lowland Leopard Frog; no ridges down the back: a fold from the eye curves round the eardrum in the American Bullfrog. B: Round dark spots in the Lowland Leopard Frog; plain green or brown, or finely mottled in the American Bullfrog. The Bullfrog grows far bigger (to 6 in or more) and gives a deep jug-o-rum call.
