The ivory millipede (Chicobolus spinigerus) is a striking species native to the southeastern United States, particularly Florida and surrounding states. Its smooth, segmented body is pale tan to ivory in color, giving it a distinctive appearance compared to darker millipede species. Adults typically reach around 9 cm in length, with females growing slightly larger than males.

These millipedes are gentle, slow-moving detritivores that thrive in humid, forested environments. In the wild, they play an important role in breaking down decaying plant matter, recycling nutrients back into the soil. Their docile nature and ease of care have made them popular in the pet trade, where they are often kept in bioactive terrariums alongside isopods and springtails.
 
In captivity, ivory millipedes require a moist, deep substrate rich in leaf litter and rotting wood, with humidity maintained around 70–80% and temperatures between 22–26 °C. They are communal and can be housed in groups without aggression, making them an excellent choice for hobbyists who enjoy observing natural behaviors.
