Interesting about the frog

  • During mating season, frogs use their sonic bladders to create the characteristic quacking mating calls.
  • The tree frog spends most of its adult life on land. Its light green color camouflages it optimally in the high grass.
  • Frogs can become over 10 years old in exceptional cases. As soon as the days get colder, the frog begins to retreat to a frost-free wintering habitat.
  • Frogs are usually found only near fish-free waters, because fish would eat the frog spawn even before the first tadpoles could hatch.
  • The tree frog spawns at night. This increases his chances of being missed by potential predators (e.g., diurnal birds) on open water.
  • The development from the tadpole to the frog is called metamorphosis (Greek for transformation / shape change). This transformation process takes between two and three months, depending on the food supply and the ambient temperature.
  • The biggest enemy of the tadpole is the voracious dragonfly larva.
  • Frogs are excellent climbers: With the adhesive pads on the ends of each finger, a frog can still find its way onto a mirror-smooth surface. A thin moisture film improves the adhesion between the surface and the frog skin.
  • The habitat of frogs has declined steadily for decades due to human intervention in natural ecosystems. Nevertheless, the frog is not threatened with extinction.
