The agile frog (Rana dalmatina) is a frog in the genus Rana in the family of the true frogs.
This species is thin and has long limbs and a pointy snout. Adult males are rarely larger than 6.5 cm, while females can grow up to 8 cm.
The call is a fairly quiet “rog … rog … rog”, and can last for up to 12 seconds. 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 attracts females. In Central Europe, spawning usually occurs in the first 20 days of March, but can also be delayed, depending on the weather.
The agile frog prefers light deciduous mixed forests with plentiful water. The open land around a forest is often also populated, as long as it is connected to the forest by shrubs.
