The EDIBLE FROG is a hybrid between the pool frog and the marsh frog and displays a morphology (size and colouration) intermediate between its parental species. Its body size is usually 8-12 cm, its hind legs are moderately long, and the metatarsal tubercle also has an intermediate size. The dorsal skin colouration varies: primary colour is green with dark brown or black patches or longitudinal stripes. Sometimes young individuals are brown, thus they are easy to confuse with common frog, moor frog or agile frog, however, the dark mask across the eyes is missing. The belly is usually mottled with grey patches, rarely it is pure white (like that of the pool frog), or dark with a black pattern (like that of the marsh frog). The thighs generally have yellow transverse bands. The male’s paired vocal sacs are usually mid-grey.
