Redworm aka red wiggler worm aka tiger worm, Eisenia fetida, Lumbricidae, Annelida
Native to Europe, this species has been introduced to every continent except Antarctica. They are specially adapted to thrive in decaying organic material, especially rotting vegetation, compost, and manure, and are rarely found in soil. When roughly handled, redworms exude a pungent defensive liquid, thus the specific name fetida.
