The marsh Frog (Rana ridibunda), is the largest native European species of frog. It occurs in the largest part of Europe, in Asian Russia to Afghanistan and Pakistan. It is also found in the Chinese province of Xinjiang. Its habitat is waters that are approximately 15 degrees Celsius (59 degrees Fahrenheit). The marsh frog is a true frog and is known as a “˜green frog’ to distinguish from other, more terrestrial frogs which are known as “˜brown frogs’.
The marsh frog reaches a maximum length of 6.75 inches, with males being smaller at only 4.75 inches long. The head is large and the hind legs are long. The long hind legs give the marsh frog exceptional jumping abilities. This species is usually green in color, but can vary from dark green to brown or gray, sometimes with lighter green lines. Western populations are darker green to black with dark spot on the back and sides. There are also three obvious green lines on the back
The diet of the Marsh Frog consists of dragonflies and other insects, spiders, earthworms and slugs. Larger frogs also eat mice, and sometimes salamanders and fish.
