The edible frog is one of three species of European water frog (along with Graf’s hybrid frog and the Italian edible frog) that is the result of a process called hybridogenesis. In this process, the hybrid species must mate with one of its parent species to reproduce, and half of the offspring are clones of the hybrid species.

In the case of the edible frog, which is the fertile offspring of a pool frog and a marsh frog, it must mate with either a pool frog or a marsh frog to produce more edible frogs.
