Trachylepis gravenhorstii, also known commonly as Gravenhorst's mabuya, is a species of skink, a lizard in the family Scincidae. The species is endemic to Madagascar. The specific name, gravenhorstii, is in honor of German zoologist Johann Ludwig Christian Gravenhorst.
The preferred natural habitats of T. gravenhorstii are rocky areas, grassland, shrubland, and forest, but is also found in coffee plantations and ylang-ylang plantations. T gravenhorstii may attain a snout-to-vent length (SVL) of 7 cm (2.8 in), and a total length (including tail) of 18 cm (7.1 in).
T. gravenhorstii is oviparous. Duméril AMC, Bibron G (1839). Erpétologie générale ou Histoire naturelle complète des Reptiles. Tome cinquième [Volume 5]. Paris: Roret. viii + 854 pp. (Euprepes gravenhorstii, new species, p. 686). (in French).

No species of the same family or order lives in Mantadia National Park, so these are its closest relatives here: other reptiles.
Possible
About 30% of wildlife watchers report a Gravenhorst's Mabuya sighting in Mantadia National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
November
In that month about 40% of wildlife watchers report a Gravenhorst's Mabuya in Mantadia National Park on a given day, against under 5% in March–June, August–September and December–January, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Gravenhorst's Mabuya sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Gravenhorst's Mabuya sightings, Mantadia National Park ranks 2nd at about 30%. The best odds are in Ranomafana National Park (Madagascar, about 50%).
GBIF citizen-science records
It is estimated from how often the Gravenhorst's Mabuya is recorded against all the reptiles logged in Mantadia National Park (9 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.
