Breeding season for Moor Frogs occurs from late March to early May. During this time, the males develop striking blue coloration on their throats and upper chests, which is used to attract females. The males gather in shallow water and produce a low croaking sound to communicate with potential mates. After successful mating, the females lay their eggs in shallow water, attaching them to aquatic plants. The tadpoles hatch within a few weeks and complete metamorphosis into adult frogs within a few months.


One of the most noticeable features of Moor Frogs is their ability to change color depending on their environment and mood. They can range from pale brown to green, blending in with the surroundings and providing effective camouflage. Additionally, the vibrant blue coloration displayed by the males during breeding season sets them apart from other frog species.

Agile Frog


The Agile Frog, scientifically known as Rana dalmatina, is a slim and agile amphibian. It has a slender body, long hind limbs, and a pointed snout. The males measure around 6 to 8 centimeters in length, while the females range from 7 to 10 centimeters.


Agile Frogs can be found in a variety of habitats throughout Austria, including grasslands, marshes, meadows, and open woodlands. They prefer areas with abundant vegetation and proximity to water sources, such as ponds, lakes, and slow-moving streams. Unlike other frog species, Agile Frogs can tolerate slightly drier conditions and are known to be more terrestrial.

Jumping Abilities

The Agile Frog is renowned for its remarkable jumping abilities. It can leap incredible distances when disturbed, utilizing its muscular hind legs and webbed feet. This agility allows the frog to quickly evade predators and escape from potential threats. Additionally, their slender body and elongated limbs enable them to move swiftly through dense vegetation and navigate challenging terrains.

Defense Mechanisms

When faced with a threat, Agile Frogs employ several defense mechanisms to ensure their survival. They have the ability to inflate their bodies, making themselves appear larger and more intimidating to would-be predators. These frogs also possess special glands on their skin that secrete toxic substances, making them unpalatable to predators. The combination of their remarkable jumping abilities and chemical defenses provides the Agile Frog with excellent protection in its natural habitats.
