Rana temporaria is a common terrestrial frog in Europe and northwestern Asia. They are resistant to cold climates and live as far north as the Arctic circle in Scandinavia, farther north than any other amphibian in the region.

Rana temporaria can be found in just about any damp habitat within its range, though they are more common in cooler upland forests and wet meadows.

Their powerful legs are not only used for jumping but for swimming as well.

They have a brown-black triangular area around their eardrum, and brown shades covering the rest of their body, though there is a lot of variation in color, with gray, olive, even yellow or pink hues as well. For the most part females tend to be larger than males. The common frog is approximately 8 cm long.

They tend to hide in damp places during the day, but often wander far from standing water. They search for food during the night or on rainy days. During the winter they stay in the soil of earth holes.

Rana temporaria consume insects, which helps control populations of mosquito's and crop-damaging insects.

Rana temporaria is difficult to recognise from Rana agilis. I think this is rana temporaria because of longer distance between the eye and the eardrum.

That one trusted so much his camouflage talent that he prefered to freeze than jumping away. If jumping away he would freeze at the moment of hitting the ground. The pose is then quite dependant of the landing. The result in this particular case is to show the under side of one feet.

Distance: 8 cm.

Jean, I like frogs, but I rarely see them around here.

Some friends of mine have already told me I have to look for a marsh in order to catch them - during the night...

Anyway, I like your image. Great composition and pov. If the image were mine, I'd try to add a little bit of saturation, but it's just an opinion.

Hi JeanMarie

I had a look across your gallery today and i saw this lovely photo that apparently i overlooksed before.
It's indeed an excellent example of the natural camuflage of the frogs.
The details here are impressive and the low angled POV offers a great close-up of the species that enhances teh composition.
Just one question: are you sure this is not Rana dalmatina? :) It really looks like that to me :)

Anyway, Bravo for this lovely macro and TFS
Horia
