Marsh frog and relatives

The marsh frog (Pelophylax ridibundus) and its relatives (edible frog Pelophylax kl. esculentus, Iberian water frog Pelophylax perezi, pool frog Pelophylax lessonae etc.) are fairly easy to recognise as a group, although it is difficult to distinguish between the different species. Collectively they are referred to as 'green frogs', or 'water frogs'.

Marsh FrogThe background colour can be green, brown or grey.  Green coloration can be vivid.  Some have a light stripe running along the back.

In spite of the variability in coloration, there are several characteristics these frogs share.

Marsh Frog - Variant 4 Alien Pool Frog

These frogs are more aquatic than our native common frog, remaining in and around the water all year (most common frogs spend a good proportion of the year on land).  They like to sunbathe and can be seen basking by the side of ponds.
