The marsh frog (Pelophylax ridibundus) is a species of water frog native to Europe and parts of western Asia. The first scientific description of the marsh frog was published in 1771 and written by Prussian zoologist Peter Simon Pallas, who gave it the scientific name Rana ridibunda after collecting specimens of it during an expedition through the Russian Empire. Pallas did not precisely specify the type locality (where he found the frogs), only noting it as "versus mare Caspium; Volgae et Iaico" (opposite to the Caspian Sea, Volga, and on the Yaik River). A more precise location of "Gurjew" on the north coast of the Caspian Sea (now the city of Atyrau in Kazakhstan) was given in a 1928 publication written by German herpetologists Robert Mertens and Lorenz Müller. However, a 1994 paper by herpetologists Alain Dubois and Annemarie Ohler noted that because Pallas never designated a holotype specimen, a neotype needs to be selected for the species. The restriction of the type locality done by Mertens and Müller is therefore invalid unless a specimen from Atyrau is designated as the neotype, which Dubois and Ohler suggest should be done...

Possible
About 30% of wildlife watchers report a Marsh Frog sighting in Almaty on a given day, based on 72 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April–May and July
In those months about 40% of wildlife watchers report a Marsh Frog in Almaty on a given day, against under 5% in November to March, the lowest months. Those are among Almaty's wettest months, with about 55 mm of rain a month against 20 mm in September.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Marsh Frog sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 32
Of the 32 cities where we can rate Marsh Frog sightings, Almaty ranks 9th at about 30%. The best odds are in Dushanbe (Tajikistan, about 60%), Antalya (Turkey, about 50%) and Jerusalem (Israel, about 40%).
GBIF citizen-science records
It is estimated from how often the Marsh Frog is recorded against all the amphibians logged in Almaty (72 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.
