Glandirana emeljanovi
In 3 days ~20% in a week ~40%
The Imienpo Station frog (Glandirana emeljanovi) is a species of frog found in Northeast Asia. It has sometimes been regarded as a subspecies of the Japanese wrinkled frog, Glandirana rugosa, with which it shares many characteristics. It is found throughout the Korean Peninsula and adjacent northeast China. It is speculated to be or have been present in the Russian Primorye region as well but attempts to find it there have been unsuccessful.
The Imienpo Station frog is found at low elevations, from 100 to 300 meters above sea level. It favors still and slow-moving waters, such as river backwaters and rice paddies. Adult frogs are 4–6 cm in length. They lay eggs in the late spring, from late April to the end of May. The tadpoles overwinter in their immature state, only undergoing metamorphosis the following summer.
Like the Japanese wrinkled frog, the Imienpo Station frog has wrinkled skin with irregular dark blotches. They are poisonous, like toads, and generally sluggish. Wikipedia →

With luck
About 10% of wildlife watchers report an Imienpo Station frog sighting in Seoul on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 9 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March to September
In those months about 10% of wildlife watchers report an Imienpo Station frog in Seoul on a given day, against under 5% in October to February, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Imienpo Station frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Seoul, in our data
Seoul is the only city on Wallace's Line with enough records to rate Imienpo Station frog sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Ranidae
The closest relatives of the Imienpo Station frog that you can see in Seoul (family Ranidae, Typical Frogs) are Black-spotted Frog (about 20%), Ueno's Brown Frog (about 10%) and Rana huanrenensis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Imienpo Station frog is recorded against all the amphibians logged in Seoul (21 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
