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.

When alive, millipedes maintain tension in theseintersegmental 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.
