Polydesmid millipedes make up the largest group of millipedes with 2,700 known species worldwide
Adult polydesmid millipedes have between 18 and 21 segments. Each segment contains two pairs of legs and wing-like projections, giving them a hairy, flattened appearance. They have many pores along their body that produce hydrocyanide, formic acid and other irritants used for defence. Most species release the liquid slowly, but some can discharge it as a spray.
Polydesmid millipedes live in forests.
Polydesmid millipedes are found throughout Australia.
Feeding and diet
Polydesmid millipedes are typically blind, living in the leaf litter and feeding on decaying vegetation. Many species are the favourite food of funnel-web spiders.
