Lumbricus terrestris is still present in a pH of 5.4, Dendrobaena octaedra at a pH of 4.3 and some Megascolecidae are present in extremely acidic humic soils. Soil pH may also influence the numbers of worms that go into diapause. The more acidic the soil, the sooner worms go into diapause, and remain in diapause the longest time at a pH of 6.4.

The Lumbricidae are a family of earthworms.About 33 lumbricid species have become naturalized around the world, [1] but the bulk of the species are in the Holarctic region: from Canada (e.g. Bimastos lawrenceae on Vancouver Island) and the United States (e.g. Eisenoides carolinensis, Eisenoides lonnbergi and most Bimastos spp.) and throughout Eurasia to Japan (e.g. Eisenia japonica, E. koreana ...
This textbook-quality illustration of the anatomy of an annelid or "ringed worm", in this case an earthworm (Lumbricus terrestris), was created from scratch by KDS444, an extremely talented illustrator.
