Archispirostreptus gigas, known as the giant African millipede, shongololo or Bongololo, is the largest extant species of millipede, growing up to 33.5 centimetres (13.2 in) in length, 67 millimetres (2.6 in) in circumference. It has approximately 256 legs, although the number of legs changes with each molting so it can vary according to each individual.

It is a widespread species in lowland parts of East Africa, from Mozambique to Kenya, but rarely reaches altitudes above 1,000 metres (3,300 ft). It lives mostly in forests, but can also be found in areas of coastal habitat that contain at least a few trees. It is native to Southern Arabia, especially Dhofar.

In general, giant millipedes have a life expectancy of about 7–10 years.
