   • 1993, Rod Preston-Mafham, The Encyclopedia of Land Invertebrate Behaviour, page 14,

     With one or two exceptions, male millipedes make direct contact with the female and transfer sperm via a pair of modified front legs (gonopods) which have been charged with semen from the genitalia situated towards the rear of the body.

   • 2005, Thomas Eisner, For Love of Insects, page 276,

     When alive, millipedes maintain tension in these^{[intersegmental]} muscles and are therefore difficult to straighten out when coiled.

     Soil millipedes (Diplopoda) possess a specific gut microbiota that differs from microbial communities in soil and leaf litter.

• The spelling "milliped" was formerly considered the only correct form by prescriptivists and is still preferred by many scientists who work with myriapods, but this spelling is by far the most common in actual use.
