caption_attribution_description: English: Fresh spawn clump of the Agile Frog (Rana dalmatina), submerged in a pool. The single spawn clump is attached to a thin branch that runs through the bale. This is a typical spawning behaviour of that species. (For better visibility, a piece of paper was pushed under the spawn.) Note: Mid April is a very unusual late date for Rana dalmatina spawning (caused by a long winter); "normal" would be about four weeks earlier in this region. Deutsch: Junger Laichballen des Springfrosches (Rana dalmatina) unter Wasser. Der Laich wurde charakteristischerweise als Einzelklumpen an einem dünnen Zweig verankert, der durch den Ballen führt. (Zur besseren Erkennbarkeit wurde für das Foto ein helles Stück Papier untergeschoben. Die untergetauchten, faustgroßen Laichballen der Art sind ansonsten oft kaum zu erkennen.) Bemerkung: Ein Laichdatum Mitte April ist extrem spät für den Springfrosch in dieser Region (verursacht durch einen strengen Spätwinter); "normal" wären eher ca. vier Wochen früher.
context_page_description: The agile frog is a European frog in the genus Rana of the true frog family, Ranidae.
context_section_description: The call is a fairly quiet "rog ... rog ... rog", and can last for up to 12 seconds, and almost sounds like a clucking chicken (listen here - https://www.youtube.com/watch?v=xIQhT4Z8LK0). They often also call under water, so the calls can only be heard from a very short distance by observers. Spawning only lasts a few days, and during this period, the males sometimes gather in large calling groups on the water surface to attract females. In Central Europe, spawning usually occurs in the first 20 days of March, but can also be delayed, depending on the weather.
  The spawn clumps consist of 450 to 1800 eggs, and are usually attached to tree branches, roots, or plant stems at depths of 5–40 centimetres (2.0–15.7 in). Therefore, they rarely sink to the bottom. Unlike the moor frog (Rana arvalis) and common frog (Rana temporaria), the agile frog does not lay its spawn all in one clump. The diameter of a single egg, not counting the gelatinous shell, is 1.5–2.1 mm (0.059–0.083 in).
