See love frog on an altitude of 1.800m

Above the altitude of 1.800m, the Alps exist a unique lake. This is the home of hundreds of frogs Rana, one of the rare creatures living on this altitude, in glacial lakes.

Although the frog lake is still covered by ice, it is still possible to hear the male frog calling children. Their search journey usually begins in the spring, when the ice in the lake begins to melt.

Male Rana frogs are usually smaller than females. When spawning, the male will jump from behind to hold the female's back tightly. The breeding process will last about 2 days or maybe longer.

In these days, the male will stay on the female's back. When the female ovulates, she will pump the sperm into the egg.

During hibernation for a few months, they often sleep in a group. This gives them an advantage when spawning, in warm weather, to find a mate quickly.

Surviving at such a height, these frogs spend 30% more eggs each season than those living in the plains to ensure a high survival rate.
