### Identification The *Amphitomeus attemsi* is a striking representative of the "flat-backed" millipedes. Measuring roughly 15–20mm in length, its body is composed of twenty distinct segments, each adorned with prominent lateral keels called paranota. These give the millipede a jagged, architectural silhouette rather than the smooth, cylindrical shape of common garden varieties. Its coloration is its most defining field mark: a deep, glossy mahogany or charcoal-black trunk contrasted sharply by cream-to-pale-yellow edges on each segment. Unlike many millipedes, *A. attemsi* lacks eyes entirely; look for its unusually long, sensitive antennae which it uses to "see" its world through touch and scent.
### Habitat & Range This species is a specialist of the southern tip of Africa, specifically endemic to the moist leaf litter of the Western Cape. You will find them most frequently in the mist-belt forests and shaded kloofs of the Table Mountain range and the Garden Route. They favor micro-habitats with high humidity—underneath rotting logs, deep within damp moss, or nestled in the rich humus layer of fynbos ecosystems where the soil stays cool.
### Behaviour Observed in the field, *A. attemsi* is a slow, deliberate traveler. It is primarily nocturnal, emerging during the damp hours of dawn or after rainfall. When threatened, it does not possess the speed to flee; instead, it performs a tight "horizontal coil," tucking its head into the center of its armored rings. During the breeding season, males use specialized legs called gonopods to transfer sperm, and females can be found constructing tiny, silken-lined earthen chambers to protect their eggs from desiccation.
### Diet As a vital detritivore, this species is a connoisseur of decay. It feeds almost exclusively on decomposing leaf litter and rotting wood, breaking down tough cellulose into nutrient-rich soil. It uses its powerful mandibles to scrape away softened plant tissues, acting as a miniature recycler that keeps the forest floor healthy.
### Fascinating Fact Despite their delicate appearance, *Amphitomeus attemsi* are chemical warriors! When agitated, they can exude a pungent liquid containing hydrogen cyanide from pores along their sides. This almond-scented cocktail is enough to deter most predators, essentially making this tiny recycler a walking, non-lethal gas chamber for any bird or beetle brave enough to take a bite.
