Eisenia fetida (older spelling: foetida), known under various common names such as redworm, brandling worm, tiger worm and red wiggler worm, red californian earth worm, is a species of earthworm adapted to decaying organic material. These worms thrive in rotting vegetation, compost, and manure; they are epigeal. They are rarely found in soil, instead preferring conditions that are inimical to some other worms. In this trait they resemble the Lumbricus rubellus.
Seems appropriate – a red wiggler worm.Tags: The Worm, Wikipedia
