Cornufer papuensis is a species of frog in the family Ceratobatrachidae. It is found in the northern parts of New Guinea and in many surrounding islands, including the Bismarck Archipelago, D'Entrecasteaux Islands, Trobriand Islands (Papua New Guinea), and Maluku Islands including Sula Islands and Seram Island (Indonesia). Common name Papua wrinkled ground frog has been coined for the species.
Males can grow to 46 mm (1.8 in) and females to 64 mm (2.5 in) in snout–vent length. The toes have a trace of basal webbing. The dorsum has numerous short skin folds. There are three dorsal color patterns morphs: unicolored, two-striped (dorsolateral stripes), and one-striped (vertebral stripe).
The male advertisement call is loud and consists of partly clustered pulses. Note length is 96–157 ms and inter-note length is 130–306 ms. Note repetition rate is relatively low at 4 per second. Cornufer papuensis is a very common species in much of its range and occurs in a variety of habitats from primary rain forest to secondary regrowth, gardens, and other heavily disturbed habitats. It is a lowland species occurring at elevations below 1,200 m (3,900... Wikipedia →

Possible
About 20% of wildlife watchers report a Papua Wrinkled Ground Frog sighting in Raja Ampat on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 5 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.
December
In that month about 40% of wildlife watchers report a Papua Wrinkled Ground Frog in Raja Ampat on a given day, against under 5% in January–February, May and August, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Papua Wrinkled Ground Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Raja Ampat, in our data
Raja Ampat is the only park on Wallace's Line with enough records to rate Papua Wrinkled Ground Frog sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Cornufer

GBIF citizen-science records
It is estimated from how often the Papua Wrinkled Ground Frog is recorded against all the amphibians logged in Raja Ampat (12 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.
