Pelophylax kl. grafi

Count shear hybrid frog ( Pelophylax " graphic " )

The Grafsche hybrid frog ( Pelophylax " graphic "), even Graf's hybrid frog, is a hybrid of the form hybridogenetische complex of water frogs. Originally, it was created by crossing the parental species marsh frog ( Pelophylax ridibundus) and the Iberian water frog ( Pelophylax perezi ). The form is named after its discoverer J.-D. Count named.

Features

The Grafsche hybrid frog reaches a head-body length of 65 to 80 ( rarely to 120 ) mm. The external appearance is very similar to the Iberian water frog, but the mating calls of the males almost sound like that of Seefrosches. A unique determination is possible only by molecular biological studies.

Occurrence and life

The distribution area of Graf 's hybrid frog covers southern France and northeastern Spain. In France, it is mainly found on the coast of the Mediterranean and Atlantic, in Spain he comes south to the Ebro before. He settled about the same habitats as the Iberian water frog.

For observations in a ground-mounted system in Poland gave females from late March to mid- July 6 to 10 spawning bales into the water, each consisting of 150 to 300 eggs.
