Characteristics : Its body is round shaped and mouth is small and short. It is yellow and light blue on the back, and it has black stripe on the yellow stomach.


Ecology : Except during the spawning season, it mostly lives on land. It hides between the rocks or under the ground during the day and gets active in the night. Like other frogs, it lures the female by sound. It comes up on the ground to mate and spawn in the rainy season. Its eggs hatch in 28~30 hours and finish metamorphosis when they are about 30 days old. Boreal Digging Frogs goes through metamorphosis faster than other frogs since they spawn in the pond or puddle made in the rainy season.


Where you can see this specie at Dongbaekdongsan : You can easily hear them crying in the night after a rain in summer. Especially it can be seen in surrounding swamp in the rainy season more easily than in Munmulggak which has rather stable water level.
