Salpidobolus sp. “Sulawesi Horned Millipede” is an unusual and visually striking species from the forests of Sulawesi, known for the small, raised projections—or “horns”—on the collum and anterior segments. These subtle structures give the millipede a rugged, almost prehistoric look, setting it apart from the smoother, more cylindrical species commonly kept in captivity. Their coloration varies from deep chocolate brown to warm reddish tones, often with a matte, textured finish that blends beautifully with the leaf‑litter environment they inhabit.
 
In the wild, these millipedes occupy humid, shaded forest floors rich in decaying wood and organic debris. They spend much of their time burrowed beneath rotting logs or deep leaf litter, emerging at dusk to forage on decomposing plant matter, fungi, and biofilm. Like other tropical millipedes, they play a vital ecological role as decomposers, helping to break down forest detritus into nutrient‑rich soil. Their behaviour is calm and deliberate, and they rely on curling tightly and secreting mild defensive compounds when disturbed.
 
In captivity, the Sulawesi horned millipede thrives in a deep, nutritious substrate that mirrors the rich, humid forest floor of its native range. They appreciate stable warmth, high humidity, and plenty of decaying hardwood to feed on. When kept in groups, they coexist peacefully and often share burrows or hiding spots. With the right setup, they become a rewarding, unusual display species—perfect for keepers who enjoy something a little different from the more commonly seen African giants.
