The dragon millipedes: spined, flanged, frequently shocking pink, and honest advertisers, since the colour warns of hydrogen cyanide-laced defensive secretions that make the group inedible and make ventilation plus hands-off handling the sensible protocol. The chemistry is defensive, not aggressive; the animal is otherwise as docile as any millipede.
Keeping is tropical detritivore standard: humid, warm, deep substrate with decaying hardwood and litter, calcium, and stability. The spined pink profile is the display and there is nothing else like it on the shelf.
Southeast Asian supply arrives in rare pulses, identification runs at the shipment level, and captive breeding is thin. The genus trades on pure spectacle to the millipede hobby's collector end, available when a shipment lands and legendary between them.
