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 40% of wildlife watchers report a Nosy Komba ground boa sighting in Ankarana National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 12 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
May and December
In those months about 50% of wildlife watchers report a Nosy Komba ground boa in Ankarana National Park on a given day, against about 10% in April, June–July and September, the lowest months. January to March have too few records to rate.

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 seen both by day and at night.
3rd of 3
Of the 3 parks where we can rate Nosy Komba ground boa sightings, Ankarana National Park ranks 3rd at about 40%. The best odds are in Ankarafantsika National Park (Madagascar, about 50%) and Montagne d'Ambre National Park (Madagascar, about 50%).
GBIF citizen-science records
It is estimated from how often the Nosy Komba ground boa is recorded against all the reptiles logged in Ankarana National Park (6 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.
