Facts about Millipedes
- 09
Certain millipede species roll their bodies into nearly impenetrable spiral coils, with African species like Zonostruma creating defensive formations so tight that predator teeth cannot penetrate the armored exterior.
- 08
Millipede eggs are laid in moist soil chambers and require 4 to 20 weeks of incubation depending on species and temperature conditions before hatching into miniature forms with only three body segments.
- 07
Millipedes first appeared during the Silurian period approximately 430 million years ago, making them among the earliest land animals to evolve.
- 06
Remarkably, millipedes breathe through spiracles, tiny openings along their body segments that allow oxygen to diffuse directly into tracheal tubes rather than relying on a centralized circulatory system like vertebrates.
- 05
Approximately 12,000 millipede species have been identified by scientists, though estimates suggest the true global diversity may exceed 80,000 species yet to be discovered and classified.
- 04
Most millipedes live 5 to 11 years in the wild, making them among the longest-lived arthropods relative to their body size.
- 03
Millipedes produce defensive chemicals called benzoquinones from specialized glands along their body, with some species spraying these toxins up to 80 centimeters away.
- 02
A millipede's body segments each contain two pairs of legs, allowing species like Narceus americanus to coordinate hundreds of appendages through a rippling wave motion traveling from rear to front.
- 01
The longest millipede species, Illacme plenipes, possesses up to 750 legs and measures nearly 10 inches in body length.
