This is widespread and common frog and have many common names, including dark-spotted frog, black-spotted pond frog, and black-spotted frog.
The adult male is about 62 mm (2.4 in) and females 74 mm (2.9 in) in snout-vent length. The dorsal coloration varies from grey to greyish-olive, olive, and green. There are usually large dark spots, a light mid-dorsal line, and two lines on dorso-lateral folds. The belly is white. The toes are webbed. Males have a paired vocal sac and nuptial pads on the first finger.
Mating season occurs soon after hibernation. Maturation probably occurs at an age of two years, and the total life span may reach 13 years. The clutch size is 1800-3000 or 600-5000 eggs. The eggs are laid in shallow water.
It is widespread and common in the Far East of Russia (with some localized declines), but it is declining in China (although it remains a common species).
They are low altitude species. The terrestrial habitats of this species include meadows, leafy and mixed pine and broadleaved forests, bush lands and desert (in Turkmenistan). They can also be found in waterbodies, including river pools, channels, lakes, reservoirs, ponds, swamps, ditches and paddy fields.
Over-exploitation in the live animal trade and water pollution are the major threats.
