Pelophylax ridibundus, commonly known as the marsh frog, is Europe's largest native frog species. It thrives in wetlands, rivers, and lakes. These frogs are known for their loud croaking and remarkable jumping ability. Their greenish-brown skin with dark spots provides excellent camouflage in aquatic environments.

Pelophylax ridibundus, commonly known as the marsh frog, typically inhabits freshwater environments such as ponds, lakes, rivers, and marshes. They prefer standing or slow-moving water bodies with abundant aquatic vegetation. The climate in these regions ranges from temperate to continental, with moderate to high humidity levels.

The marsh frog is a semi-aquatic species that plays a crucial role in its ecosystem as both predator and prey. It feeds on a wide range of invertebrates and small vertebrates, contributing to the control of insect populations. It also serves as an important food source for birds, mammals, and larger amphibians. The species has adapted to various environmental conditions, showing some regional variations due to subspecies or specific local adaptations.
