Illustration of American Giant Millipede (Narceus americanus)

The American Giant Millipede is one of North America's largest arthropods, reaching 4 inches, with a cylindrical dark gray body banded with pink-orange segment margins. Unlike centipedes, it is harmless and slow-moving, feeding on decomposing plant matter. When threatened it coils into a tight spiral and secretes benzoquinones — chemicals that can temporarily stain skin yellow.
