Edible frog

It is used for food, particularly in France as well as Germany and Italy, for the delicacy frog legs.

The edible frog is introduced in Spain,[4] Norway[5] and the United Kingdom.

[9][10][12] The hybrid populations are usually propagated by mating (backcrosses) with a sympatric parental species – P. lessonae (LL) or P. ridibundus (RR) – providing the second, discarded parental genome (L or R respectively).

[13][11][12] For example, in the most widespread so called L–E system, edible frogs Pelophylax kl.

[9][12] Because this hybrid requires another taxon as a sexual host to reproduce, usually one of the parental species, it is a klepton,[14][15][16] hence the addition of the "kl."

Pelophylax esculentus complex
Example crosses between pool frog ( Pelophylax lessonae ), marsh frog ( P. ridibundus ) and their hybrid, edible frog ( P. kl. esculentus ). The first is the primary hybridisation generating the hybrid; the second is the most widespread type of hybridogenesis. [ 9 ] [ 11 ]
