Giant Pill Millipedes (Sphaerotheriida) are found in Southern Africa, Madagascar, South and Southeast Asia, Australia and New Zealand. They like moist habitats in leaf litter on forest floors
They can roll into a ball if disturbed, smaller ones can be the size of a cherry, slightly larger ones can be golf ball. The largest which come from Madagasgar can be the size of an orange!

The Giant Millipedes first and last dorsal plate align perfectly with no gap, making a tightly sealed ball which most predators can't open, however there are some including snails in South Africa which specialise in feeding on them. Also Meerkats and birds will hunt and eat them!
They are ground dwelling detritivores, and feed on dead organic matter, such as leaves and wood on the forest floor. They play an important role in decomposition helping to break down organic matter back into the soil!
A few Giant Millipedes can produce sound!
Sphaeromimus pill-millipedes live in the rainforests of southeastern Madagascar.....Males have a structure on their anterior telopod, known as the harp, which has several ribs and is able to produce sounds. This stridulation organ is still not well understood, but may play a role during courtship. Source
The name for them in the local language [in Madagasgar] is 'tainkintana' which means 'star droppings'!
Their antennae are very dexterous and mobile, and resemble elephant trunks as they probe their environment!

Their sex lives have 4 different phases....
The first phase is when a male detects a female, and orientates itself by positioning its anal shield towards the potential partner. Second, once the male is in contact with the female it starts to make stridulation sounds and vibrations. If the female recognises the male and is receptive, she will open up from her rolled-up position, or not roll up, and the male will then move below the female and grab her front legs with his telopods
The male then ejects sperm from his penises (he has one small penis at the base of each of the first pair of legs on the second segment), and transfers the sperm backwards along his legs and into the female opening which is on her second pair of legs. The two millipedes will then separate. After that, the female lays her eggs in the soil and covers them with a mud layer for protection. The eggs hatch into very small, pale pill-millipedes. Source
They are slow movers and are able to burrow into the soil and leaf litter. They also come in a nice variety of colours and patterning!

Adult females have 21 leg pairs (42 in total), while males have an additional 2 leg pairs, which are probably used to grasp onto the females during mating!
