Archispirostreptus gigas

Archispirostreptus gigas, known as the giant African millipede or shongololo, 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.^[2]

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).^[3] It lives mostly in forests, but can also be found in areas of coastal habitat that contain at least a few trees.^[3] It is native to Southern Arabia, especially Dhofar.

In general, giant millipedes have a life expectancy of about 7–10 years.^[4] Giant millipedes have two main modes of defence if they feel threatened: curling into a tight spiral exposing only the hard exoskeleton, and secretion of an irritating liquid from pores on their body. This liquid can be harmful if introduced into the eyes or mouth.^[4] Because of this defense, A. gigas is one of the few invertebrates that driver ants are incapable of taking as prey. The chemicals identified in this millipede’s defensive secretion are toluquinone and 2-methoxy-3-methylbenzoquinone^[5]

Small mites are often observed crawling on their exoskeleton and among their legs. The millipedes have a symbiotic relationship with these mites, in which the mites help clean the millipede's exoskeleton in exchange for food and the protection of their host.^[6]

A docile species, A. gigas is sometimes seen in the pet trade.^[7] However, the U.S. federal government requires anyone bringing giant millipedes into the country to have permits for them.^[8]

This package lacked required import permits and was misrepresented in an attempt to bypass federal regulations.
