It has many pairs of tiny legs along its body, giving it a segmented, worm-like appearance. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Arthropoda - **Class:** Diplopoda - **Order:** Spirobolida - **Family:** Spirobolidae - **Genus:** Narceus ## Interesting facts - A baby millipede is born with only a few legs and gains more as it grows! - Millipedes are ancient; some fossil species grew over two meters long! - They move their legs in a smooth, wave-like motion, like a slow ripple. - Unlike centipedes, millipedes eat decaying plants, not other animals. ## Special abilities - **Defensive Goo:** American Giant Millipede Complex can secrete a stinky, irritating liquid to ward off predators because of glands along its body. - **Armor Roll:** American Giant Millipede Complex can coil its body tightly into a spiral to protect its soft underside from danger. - **Ground Navigator:** American Giant Millipede Complex has hundreds of tiny legs that help them push through soil and leaf litter with ease. ## Measurements & details - **Length:** 7 cm - **Lifespan:** 3 years - **Leg Count:** 200 ## Diet & Feeding They are nature's recyclers, munching on dead leaves and decaying plants! - **Age differences:** null - **Primary Foods:** Decaying Leaves, Rotting Wood, Fungi, Moist Soil - **Foraging Method:** Foraging ## Ecological connections - **Eaten by:** [American Robin](https://www.snappit.app/explore/american-robin) (*Turdus migratorius*) — A common bird that preys on millipedes. - **Eaten by:** [White-footed Mouse](https://www.snappit.app/explore/white-footed-mouse) (*Peromyscus leucopus*) — Small rodent that sometimes consumes millipedes. - **Depends on:** [White Oak](https://www.snappit.app/explore/white-oak) (*Quercus alba*) — Helps decompose fallen leaves from this tree. ## Traits - [Solitary](https://www.snappit.app/explore/traits/solitary): Solitary animals live alone for most of their lives, only interacting with others for mating or parental care. - [Herbivorous](https://www.snappit.app/explore/traits/herbivorous): This trait characterizes organisms whose diet consists entirely or primarily of plant material. - [Decomposer](https://www.snappit.app/explore/traits/decomposer): Describes organisms that break down dead organic material, recycling nutrients back into the ecosystem. - [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life. - [Nocturnal](https://www.snappit.app/explore/traits/nocturnal): Nocturnal animals are primarily active during the nighttime hours, typically resting or sleeping during the day. ## Collections - [Invertebrates](https://www.snappit.app/explore/collections/invertebrates) ## Safety **Danger:** 0/5 · No known danger These millipedes are harmless and great to observe but should not be handled. ## Frequently Asked Questions ### How to identify American Giant Millipede Complex?
