The enormous amount of plant and animal material on the forest floor is decomposed by fungi and bacteria in what is called saprotrophic nutrition – a process in which decaying matter is absorbed and metabolised on a molecular scale. The bigger bits are left for other recyclers such as worms, flies and millepedes, a group of animals often referred to as detritivores. Especially the millepedes are fascinating, roaming through the delicious rotting matter in search for food. Heavily armoured with dorsal plates, equipped with chemical-secreting glands and able to curl themselves into a tight pinball-like ball, these millepedes are able to bulldoze along relatively undisturbed. We thought that the orange-coloured giant Pill Millepede (Glomeridae) and the Tractor Millepede (Polydesmidae) we encountered in Danum Valley were particularly impressive!
