Staurois tuberilinguis (common names: Borneo splash frog, green-spotted rock frog) is a semi-aquatic amphibian of the true frog family (Ranidae). This diurnal and crepuscular frog is also commonly associated with its very close relative Staurois parvus (common name: Borneo rock frog). In fact, many do not consider the two species to be taxonomically separate. This species is commonly found within the tropical rainforests of on Borneo, Malaysia next to fast-flowing rivers and streams. Due to the frog's noisy choice of habitat, S. parvus are well-known for their multi-modal system of communication that combines acoustic calls with visual display signals. S. parvus seems to be in decline in part of its range, but overall is listed as being of "least concern" in the IUCN Red List of Threatened Species. It is threatened by habitat loss, especially by deforestation and sedimentation of streams.
S. parvus tadpoles possess a strongly depressed body with small subcutaneous eyes, tiny external nares, a vermiform appearance with a long tail and reduced fins, and nearly pigmentless skin. Compared to S. tuberilinguis, the two tadpoles are nearly indistinguishable... Wikipedia →

Likely
About 40% of wildlife watchers report a Green-spotted Foot-flagging Frog sighting in Kinabalu Park on a given day, based on 56 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 40 amphibians we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July–September and December
In those months about 50% of wildlife watchers report a Green-spotted Foot-flagging Frog in Kinabalu Park on a given day, against under 5% in May, the lowest month.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Green-spotted Foot-flagging Frog sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Green-spotted Foot-flagging Frog sightings: about 40% of wildlife watchers there report one on a given day.
Same genus: Staurois
The closest relatives of the Green-spotted Foot-flagging Frog that you can see in Kinabalu Park (genus Staurois) are Black-spotted Rock Skipper (about 40%) and Rock Skipper (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green-spotted Foot-flagging Frog is recorded against all the amphibians logged in Kinabalu Park (56 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.
