In Madagascar, millipedes rarely go unnoticed. In fact, the island is home to an incredible diversity of myriapods, many of which are endemic and particularly remarkable for their size, coloration, or behavior. Though discreet, these creatures play a crucial role in the island’s forest ecosystems.
One of the most striking species is Spirostreptus sculptus, a giant dark brown millipede that can reach up to 30 cm in length. After more than a century without any recorded sightings, it was recently rediscovered in the Makira rainforest. This harmless forest giant feeds mainly on dead leaves and contributes significantly to the decomposition of organic matter. Its late sexual maturity and limited reproduction may explain its rarity in scientific observations.
Another notable species is Aphistogoniulus corallipes, easily recognized by its vivid red and black stripes. It inhabits lowland tropical rainforests and is now listed as Critically Endangered by the IUCN. Its bright coloration has made it popular among terrarium hobbyists, which further threatens its survival in the wild.
Even more unique are some millipedes from the order Sphaerotheriida, which can curl into a perfect ball as a defense mechanism. However, this clever behavior does not protect them from all predators—some meerkats have been observed using them as projectiles to force them to unroll.
Beyond their ecological roles, millipedes also benefit other species. For example, red-fronted lemurs have been observed using millipede secretions as a form of self-medication to repel internal parasites, a natural remedy that continues to intrigue researchers.
Often misunderstood or unfairly feared, these creatures reflect Madagascar’s exceptional natural wealth. Protecting their habitats also means preserving an entire ecological balance—one still full of secrets waiting to be uncovered.
Comparative Table of Key Malagasy Millipede Species :
| Species | Maximum Size | Coloration | Primary Habitat | Conservation Status |
| Spirostreptus sculptus | 27.5–30 cm | Dark brown | Makira rainforest | Not extinct, but extremely rare |
| Aphistogoniulus corallipes | Less than 10 cm | Red and black | Lowland tropical rainforest | Critically Endangered (IUCN) |
| Sphaerotheriida (order) | Variable | Variable | Forests and savannas | Not assessed (relatively common) |
