There is a similarly named version titled Worms Eat Our Garbage: Classroom Activities for a Better Environment, first published in 1993 and directed at classroom education. [5] In 2017 Joanne Olszewski updated the book for a 35th anniversary edition, and in addition to Appelhof's work the new book contains information on invasive species and ...
Eudrilus eugeniae, also called the "African nightcrawler", is an earthworm species native to tropical west Africa and now widespread in warm regions under vermicompost; it is an excellent source of protein and has great pharmaceutical potential. [1] [2]
Vermicast (also called worm castings, [a] worm humus, worm poop, worm manure, or worm faeces) is the end-product of the breakdown of organic matter by earthworms. [1] These excreta have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than the organic materials before vermicomposting.
Eisenia fetida, known under various common names such as manure worm, [2] 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.
The length of earthworms can vary from 1.0 cm (0.39 in) to 2 m (6 ft 7 in). [3] The number of spermathecal pores is normally paired, but multiples can be present in some species. The location of spermathecal pores and how they are positioned in different segmental locations is used in the identification of different megascolecidids.

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.
In ecosystems, earthworms such as Lumbricus rubellus increase the rate of transfer between trophic levels by making it easier for plants to uptake nutrients. In food chains, earthworms such as Lumbricus rubellus are primary consumers whose role is converting the energy synthesized by photosynthetic plants into food for animals at higher trophic ...
