The Nosy Komba ground boa (Sanzinia volontany) is a boa species endemic to the island of Madagascar. It is brownish in colour and is found on the western side of the island. It was once considered conspecific with the Madagascar tree boa. Like all other boas, it is not venomous.
Endemic to Madagascar. The type locality given is "Madagascar". Arboreal and generally nocturnal, it feeds on mammals and birds. Its thermoreceptive pits help it to locate its prey. It will also leave the trees to actively hunt for small mammals on the ground. It favors trees and shrubs near streams, rivers, ponds and swamps.

Likely
About 50% of wildlife watchers report a Nosy Komba ground boa sighting in Ankarafantsika National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 20 reptiles we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
April
In that month about 80% of wildlife watchers report a Nosy Komba ground boa in Ankarafantsika National Park on a given day, against about 10% in June to August, the lowest months. That is one of Ankarafantsika National Park's driest months, with about 55 mm of rain against 560 mm in January. February and March have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Nosy Komba ground boa sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Ankarafantsika National Park, in our data
Ankarafantsika National Park is the only park on Wallace's Line with enough records to rate Nosy Komba ground boa sightings: about 50% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Nosy Komba ground boa is recorded against all the reptiles logged in Ankarafantsika National Park (18 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.
