The Asian giant toad (Phrynoidis asper), sometimes referred to as the river toad, is a species of true toad native to Mainland Southeast Asia and the Greater Sundas. It is a medium-large toad, but it is easily confused with its larger relative, the giant river toad (P. juxtasper).
Phrynoidis asper is generally a dark grey, green, black or brown in color, and is heavily covered in tubercles. Females can reach up to 14 cm (5.5 in) in snout–to–vent length and males up to 10 cm (3.9 in). They can be commonly found near stream and rivers.

Likely
About 40% of wildlife watchers report a River Toad sighting in Jakarta on a given day, based on 127 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 18 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.
November
In that month about 60% of wildlife watchers report a River Toad in Jakarta on a given day, against about 20% in April, the lowest month.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most River Toad sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 4
Of the 4 cities where we can rate River Toad sightings, Jakarta ranks 2nd at about 40%. The best odds are in Malang (Indonesia, about 50%).
Same family: Bufonidae
The closest relatives of the River Toad that you can see in Jakarta (family Bufonidae, True Toads) are Common Indian Toad (about 80%) and Crested Toad (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the River Toad is recorded against all the amphibians logged in Jakarta (127 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.
