A family of small, primitive segmented worms or annelids, typically microscopic soil-dwelling organisms.
From Latin 'anellus' (small ring) + the scientific suffix '-idae' (family classification). The name refers to the ring-like segments characteristic of these small worms.
These tiny worms are so abundant in soil that a handful of garden dirt contains thousands of them, yet most people never know they exist—they're part of the invisible ecosystem that makes soil fertile!
