E. fetida is a species only found in temperate and boreal countries. In nature, this epigeic species lives near the soil surface, within the decomposing organic matter, or in dead woods. Due to its high affinity with composting material, it has become the main species used in vermiculture. It is also a central species as model in toxicological studies and scientific research on earthworm molecular biology. |
