Giant African Millipede

The Giant African Millipede (Archispirostreptus gigas) is the largest species of millipede. They live in African rain forests, where they roam the forest floor searching out decaying vegetation to consume. Millipedes are none venomous, unlike centipedes which are carnivorous and will attack without provocation. There are over 10,000 species of millipedes in the world.
When threatened, the Giant Millipede will curl up into a spiral for self defense.
