Calumma glawi is a species of chameleon, a lizard in the family Chamaeleonidae. The species is endemic to Madagascar. The specific name, glawi, is in honor of German Herpetologist Frank Glaw. The preferred natural habitat of C. glawi is forest, at altitudes of 1,030–1,200 m (3,380–3,940 ft).
C. glawi is oviparous. Böhme W (1997). "Eine neue Chamäleonart aus der Calumma gastrotaenia-Verwandtschaft Ost-Madagaskars ". Herpetofauna 19 (107): 5–10. (Calumma glawi, new species). (in German).

Likely
About 50% of wildlife watchers report a Glaw's Chameleon sighting in Ranomafana National Park on a given day, based on 105 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 29 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.
May and August–September
In those months about 70% of wildlife watchers report a Glaw's Chameleon in Ranomafana National Park on a given day, against about 10% in March, the lowest month. Those are among Ranomafana National Park's driest months, with about 100 mm of rain a month against 450 mm in January.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Glaw's Chameleon sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Ranomafana National Park, in our data
Ranomafana National Park is the only park on Wallace's Line with enough records to rate Glaw's Chameleon sightings: about 50% of wildlife watchers there report one on a given day.
Same genus: Calumma
The closest relatives of the Glaw's Chameleon that you can see in Ranomafana National Park (genus Calumma) are Cryptic Chameleon (about 80%), O'Shaughnessy's Chameleon (about 80%) and Deceptive Chameleon (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Glaw's Chameleon is recorded against all the reptiles logged in Ranomafana National Park (105 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.
