Marsh frogs like to spend all their time in, or within jumping distance of, water. Both powerful swimmers and amazing jumpers, they often just stand in the mud, ready to leap into deep water at the first sign of trouble and landing with a resounding plop. They are robust and warty members of the green frog group, have a laughing call and a talent for singing whose quality is judged by females waiting to mate. Europe's largest native frog (reaching 17cm long) are now enlarging their range, partly naturally but mostly through being sold for garden ponds.
