Zoosphaerium is a genus of giant pill millipedes endemic to Madagascar.

[1] The largest of the known species of giant pill millipede known is Zoosphaerium neptunus,[2] which is capable of growing to lengths of 90 mm (3.5 in).

[3] Madagascar is a hotspot for biodiversity and localized endemism, as a result some species occur sympatrically as microendemics.

[4] Species within the genus Zoosphaerium can be found living amongst damp leaf litter in forest and jungle habitats.
