Scaphiophryne marmorata is a species of frog in the family Microhylidae. It is commonly known as the green burrowing frog and the marbled rain frog. It is endemic to Madagascar. It is classified as "Vulnerable" by the IUCN as it is threatened by habitat loss.
A revision of the Scaphiophryne marmorata complex was undertaken in 2003 and as a result, Scaphiophryne spinosa was removed from synonymy with Scaphiophryne marmorata and a new species, Scaphiophryne boribory, was described.
The female green burrowing frog grows to a length of about 40 millimetres (1.6 in) but the male is smaller at 30 millimetres (1.2 in). It is nearly globular in shape with a small, flattened head, short snout, prominent eyes and well muscled limbs. The skin of the back is mostly smooth but there are two symmetrical pairs of thorny tubercles on the upper back. The digits on both fore and hind limbs are elongated which helps the frog to clamber around in trees and bushes. There are expanded discs at the end of the fingers which is a distinctive feature of this species. The hind limbs are short with bony flanges on the heels to help with digging. The colour is a bright green liberally... Wikipedia →

Likely
About 40% of wildlife watchers report a Marbled Rain Frog sighting in Mantadia National Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 7 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.
January
In that month about 70% of wildlife watchers report a Marbled Rain Frog in Mantadia National Park on a given day, against under 5% in June to September, the lowest months. That is one of Mantadia National Park's wettest months, with about 340 mm of rain against 60 mm in September.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Marbled Rain Frog sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Mantadia National Park, in our data
Mantadia National Park is the only park on Wallace's Line with enough records to rate Marbled Rain Frog sightings: about 40% of wildlife watchers there report one on a given day.
Same order: Anura
The closest relatives of the Marbled Rain Frog that you can see in Mantadia National Park (order Anura, Frogs and Toads) are Baron's Mantella (about 50%), Madagascar Bright-eyed Frog (about 30%) and Madagascar Jumping Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Marbled Rain Frog is recorded against all the amphibians logged in Mantadia National Park (38 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.
