Scaphiophryne spinosa is a species of frog in the family Microhylidae. It is endemic to eastern Madagascar. It has been considered synonym of Scaphiophryne marmorata, but a revision in 2002 restored its species status. It inhabits pristine rainforests, swampy forests, forest edges, and degraded forests; it is absent from very open areas. Habitat loss is a threat to this species. Wikipedia →

Possible
About 20% of wildlife watchers report a Spiny Rain Frog sighting in Ranomafana National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 14 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.
January
In that month about 60% of wildlife watchers report a Spiny Rain Frog in Ranomafana National Park on a given day, against under 5% in February and April–October, the lowest months. That is one of Ranomafana National Park's wettest months, with about 450 mm of rain against 80 mm in September.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Spiny Rain 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 Ranomafana National Park, in our data
Ranomafana National Park is the only park on Wallace's Line with enough records to rate Spiny Rain Frog sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Spiny Rain Frog is recorded against all the amphibians logged in Ranomafana National Park (7 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.
