Réduises

Réduises are a group of primitive terrestrial arthropods belonging to the class Pauropoda, closely related to millipedes and centipedes. They are small, segmented creatures typically measuring between 1 and 3 millimeters in length, with a cylindrical, soft-bodied appearance. Réduises are often found in moist, decaying organic matter such as leaf litter, soil, and compost, where they play a role in breaking down detritus and recycling nutrients.

These organisms possess a distinct body structure divided into many similar segments, each bearing paired appendages. Unlike millipedes, réduises lack true legs and instead have unjointed, bristle-like appendages called pseudopods. Their bodies are covered in fine hairs and scales, which help retain moisture in their damp habitats. They are generally considered harmless to humans and other animals, feeding primarily on fungi, bacteria, and decaying plant material.

Réduises are primarily found in temperate and tropical regions worldwide, with the highest diversity observed in moist, forested environments. They are most active at night and during periods of high humidity. Due to their small size and cryptic lifestyle, they are rarely observed in the wild and are often overlooked in ecological studies. Their role in soil ecosystems highlights their importance in maintaining nutrient cycles and supporting plant growth.

Fossil evidence suggests that réduises have existed for millions of years, with some of the earliest records dating back to the Carboniferous period. Despite their ancient lineage, they remain relatively little-studied compared to other arthropods. Their simple anatomy and limited mobility make them useful models for understanding early terrestrial arthropod evolution.
