Millipedes have many legs (milli= "1,000"; pede= "feet"). While no species discovered to date has 1,000 legs, hundreds of legs is the norm with two legs on each of several hundred body segments in more elongate species. Their numerous legs give them the power to burrow quickly into soil, but other defenses make the difference when cornered by a predator. Typically, a millipede has rows of pores (ozopores) that connect to glands that secrete toxic liquids. Millipedes that are brightly colored, or even fluorescent (such as Motyxia sp.), may be flashing a warning about their toxicity to predators. Some millipedes also can roll up into a defensive ball, exposing their hard external coverings (exoskeletons) and protecting their softer bellies. Despite their many defenses, millipedes are prey for some animals. Meerkats, for example, have overcome millipede defenses by developing immunity to their toxins and finding ways to clean them, such as rolling millipedes in sand before eating them.
