Earthworms Classification
The vermitechnological genus “earthworms” contains manure, brandling and other species of earthworms. Dogel (1975) considers them belonging to the brandling worm family (Lumbricidae), higher oligochaetes order (Lumbricomorpha), oligochaetes type (Оligochaeta), clitellates subtype (Clitellata), annelids type (Annelida), metazoan subkingdom, animal kingdom.
However, T.S. Perel (1979) believes the systematic division of the earthworm family is a complicated issue.
V. G. Matveeva, T. S. Perel (1982) divided earthworms into three ecological groups according to vertical distribution of earthworms in soil:
- surface and compost dwellers (E.fetida, Dendroboena oktaedra, Lumbricus castaneus);
- soil-litter (Lumbricus rubellus, Eisenia nordenskioldi);
- burrow dwellers of the deep soil layers (Lumbricus terrestris, Dendroboena platura).
