Millipedes
Millipedes are a group of arthropods with their defining characteristics being two pairs of jointed legs on most of their body segments. Each segment has two single parts fused. Whenever it is stretched out, the millipede has a very elongated and cylindrical body.
Because they cannot move very fast and are not able to sting, the millipedes tend to curl into a tight coil whenever they feel threatened. The hard exoskeleton acts like armor to protect the delicate legs and the creature’s underbelly. They can also ooze toxic cyanide and foul-tasting chemical from the small pores on the sides of their bodies.
