description Moor Frog Overview

The moor frog, Rana arvalis, is a small true frog distributed across much of northern and central Europe into western Siberia. It inhabits damp meadows, bogs, woodland edges, floodplains, and other wetlands, breeding in shallow water during spring. Breeding males in many populations temporarily develop a conspicuous blue coloration, while females and nonbreeding animals remain predominantly brown with darker markings.

help Moor Frog FAQ

Why do male moor frogs turn blue?

During the brief spring breeding season, male moor frogs turn a striking bright blue color as a form of sexual display. This vivid coloration lasts only a few days and is used to attract females and establish dominance among other males.

Are moor frogs poisonous to humans?

Despite their vivid blue appearance during mating season, moor frogs are completely harmless and not poisonous to humans. Their bright coloration is temporary for mating purposes and does not indicate the presence of toxins.

Where can I find the moor frog in the wild?

The moor frog (Rana arvalis) is native to a wide range across Europe and central Asia. They prefer damp, swampy habitats like moorlands, wet meadows, and flooded forests.

Is the moor frog currently an endangered species?

While the moor frog is not globally endangered, local populations are declining in parts of Western Europe due to habitat loss. They require specific wetland environments to breed, making them vulnerable to agricultural drainage and urban development.
