Giant African millipede
Archispirostreptus gigas

— Where the name comes from
The name assembles three Greek words: archi-, “first, founding”, speîra, the spiral, and streptós, “twisted”. It is therefore “the ancient one coiled in a spiral”, and describes the posture the animal takes when disturbed, rolling up with its head at the centre. The name of the millipede order, Diplopoda, says instead “double feet”: they have two pairs of legs per segment, not one.

— What sets it apart
No millipede has a thousand legs, and the word was a promise the group kept only in 2021, when an Australian mining borehole turned up Eumillipes persephone, an animal as thin as a thread with 1,306 legs: the first true millipede in history. This African species, among the largest in the world, stops at a little over 250. As for defence, it does not bite: it secretes from its flanks a fluid containing quinones and sometimes traces of cyanide, enough to deter a predator and to stain the fingers of anyone who picks it up for days.
