Australia has more than 1000 types of millipedes. Most millipedes are nocturnal and feed on leaf litter and mosses of our forests. One introduced species, the Portuguese Millipede is the one that most of us are familiar with and is easily identified ar shiny black in colour and curls into a flat spiral if disturbed. As Portuguese Millipedes have no natural predators, they often breed into plague numbers. Millipedes protect themselves by extruding a foul smelling, and in some cases caustic, liquid.
