These worms thrive in rotting vegetation, compost, and manure. They are epigean, rarely found in soil.
Eisenia fetida (Savigny, 1826) with head regeneration, in an anterior direction, possible at each intersegmental level back to and including 23/24, while tails were regenerated at any levels behind 20/21; thus two worms may grow from one. [43]
