[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).

[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.

[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.

[7] However, the U.S. federal government requires anyone bringing giant millipedes into the country to have permits for them.
