As a recent discovery, relatively little is currently known about the biology of Cooks’ cave millipede. Nevertheless, like most millipedes, this species probably feeds on detritus, which is likely to have been deposited by underground streams or by rainwater that has drained from the surface. Living in the darkness, Cooks’ cave millipede has little use for vision, and instead relies on its antennae, which not only help this species to feel objects, but also detect chemical signals in its environment (8).
Millipede reproduction involves the male transferring sperm to the female using specially modified legs called gonopods, after which, the female lays numerous eggs. The eggs hatch into a legless, pupoid stage, which then moults into a more developed form called the first “stadium” which has legs, but no ocelli. With each subsequent moult, the young millipede grows larger, gaining additional segments, legs and ocelli (8).
