Pickeral Frog (Lithobates palustris)

Pickeral Frog (Lithobates palustris) and Northern Leopard Frog (Lithobates pipiens) / Atlantic Coastal Leopard Frog look very similar to each other because of the spots but the Pickeral frog’s spots are more rectangular than the Northern Leopard / Atlantic Coastal Frog. Now for Atlantic Coast Leopard Frog vs Northern Leopard Frog, the Atlantic Coastal Frog has more white in its tympanum than the Northern.
