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. Wikipedia →

Rare
Under 5% of wildlife watchers report a Sumatran Puddle Frog sighting in Singapore on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 20 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Sumatran Puddle Frog in Singapore on a given day, against under 5% in December to October, the lowest months. That is one of Singapore's wettest months, with about 280 mm of rain against 100 mm in February.
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.
2nd of 2
Of the 2 cities where we can rate Sumatran Puddle Frog sightings, Singapore ranks 2nd at under 5%. The best odds are in Kuching (Malaysia, about 30%).
GBIF citizen-science records
It is estimated from how often the Sumatran Puddle Frog is recorded against all the amphibians logged in Singapore (11 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.
