How do you identify different types of earthworms?
For example, the number of segments from the peristomium to the clitellum and the number of segments which make up the clitellum are species-specific in earthworms. This means that, if two earthworms have different numbers of segments to the start of the clitellum, they are different earthworm species.
How earthworms are classified based on ecological strategies?
Earthworms are classified as epigeics, anecics and endogeics based on their ecological strategies. Epigeics are the surface dwellers e.g., Perionyx excavaus and Eudrilus eugeniae. Anecics are found in the upper layers of the soil e.g., Lampiro mauritii, Lumbricus terrestris.
