The Sumatran puddle frog (Occidozyga sumatrana) is a species of frog in the family Dicroglossidae. It might be endemic to Indonesia. However, it has often been confused with Occidozyga laevis, and was also for long considered to be its junior synonym.
Its known distribution is restricted to Sumatra and Java, as well as Sipora and Simeulue islands. The true distribution of this species is therefore poorly known but likely to be wider (perhaps from India through Malaysia to southern China). Its natural habitats are tropical moist lowland forests, rivers, intermittent freshwater marshes, and canals and ditches. It is threatened by habitat loss. However it has most recently been reported in Singapore on August 23, 2018.

Possible
About 20% of wildlife watchers report a Sumatran Puddle Frog sighting in Kubah National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 38th most-seen of the 41 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November
In that month about 50% of wildlife watchers report a Sumatran Puddle Frog in Kubah National Park on a given day, against under 5% in October and December–August, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Sumatran Puddle Frog sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Kubah National Park, in our data
Kubah National Park is the only park on Wallace's Line with enough records to rate Sumatran Puddle Frog sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Dicroglossidae
The closest relatives of the Sumatran Puddle Frog that you can see in Kubah National Park (family Dicroglossidae, Fork-tongued Frogs) are Matang Creek Frog (about 60%), Giant River Frog (about 50%) and Broad-headed Creek Frog (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sumatran Puddle Frog is recorded against all the amphibians logged in Kubah National Park (7 verified sightings from 2019 to 2026), 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.
