The Sulawesi Giant Squirrel occurs on Sulawesi. Its back is flecked with buff, orange, and black, while its belly is reddish. It is active by day and also uses the forest understory and ground.
The dorsal fur is flecked with buff, orange, and black, and the belly is reddish. The ears have black tufts, and a pale ring surrounds each eye.
This diurnal, semi-arboreal squirrel moves in the understory and on the ground rather than mainly in the canopy. It eats seeds, fruits, and insects, and may dig into rotten wood for arthropods.
