Status

Green Frog (Lithobates clamitans) is an ubiquitous frog species of shallow freshwater, including ponds, lakes, ditches, temporary seasonal pools, slower creeks and rivers, bogs, and many other similar habitats. Green Frogs are generalist predators of a wide variety of prey within its environment, including invertebrate and small vertebrate prey. The call sounds like a sudden, loud pluck of a banjo string (Conant & Collins, 1998). This frog is found abundantly in most areas of Maryland and is recorded from every county (Maryland DNR).

Description

The dorsolateral ridges on the back end before reaching the groin, and there isn't a well-developed pale facestripe parallel to the mouth (cf. Leopard and Pickerel Frogs).
