A busy giant pill millipede in the highland rainforest of North Sumatra, 1600m above sea level. Despite the similar appearance, it is not closely related to woodlice. But they are both detritivores, feed on organic materials and play important roles in recycling nutrients in their ecosystems.
P.S. Correction: its Chinese name should be 球马陆.
