Wikipedia wrote:Eisenia fetida (older spelling: foetida), known under various common names such as manure worm, redworm, brandling worm, panfish worm, trout worm, tiger worm, red wiggler worm, etc., is a species of earthworm adapted to decaying organic material. These worms thrive in rotting vegetation, compost, and manure. They are epigean, rarely found in soil. In this trait, they resemble Lumbricus rubellus.
Red wigglers are reddish-brown in color, have small rings around their body and have a yellowish tail. They have groups of bristles (called setae) on each segment that move in and out to grip nearby surfaces as the worms stretch and contract their muscles to push themselves forward or backward.
Eisenia fetida worms are used for vermicomposting of both domestic and industrial organic waste. They are native to Europe, but have been introduced (both intentionally and unintentionally) to every other continent except Antarctica. Tiger worms are also being tested for use in a flushless toilet, currently being trialled in India, Uganda and Myanmar.
Eisenia fetida also possess a unique natural defense system in their coelomic fluid: cells called coelomocytes secrete a protein called lysenin, which is a pore-forming toxin (PFT), which is able to permeabilize and lyse invading cells. It is best at targeting foreign cells whose membranes contain significant amounts of sphingomyelin. (Lysenin is also toxic to organisms lacking sphingomyelin in their cell walls, including B. megaterium, though the pathway is not understood).
Wikipedia wrote:Perionyx excavatus is a commercially produced earthworm. Popular names for this species include composting worms, blues, or Indian blues. This species is marketed for its ability to create fine worm castings quickly. It has recently become more popular in North America for composting purposes.
This species belongs to the genus Perionyx. It may have its origins in the Himalayan mountains. This species is suited for vermicomposting in tropical and subtropical regions.
