Earthworm overview
Taxonomy
The sub-order Lumbricina belongs to the phylum Annelida, Class Clitellata and order Haplotaxida. It is considered that this sub-order consists of the so-called "true earthworms". To its part, the family Haplotaxidae, sub-order Haplotaxina, is considered to be phylogenetically a basal group in regard to the classical terrestrial earthworms. The very first earthworm species, Lumbricus terrestris, was described by Carl Linnaeus in 1758. Savigny showed, in 1826, that earthworms were in fact composed of several species. Today, 20 families have been described and up to 5000 valid species are recognized.

Ecology - Ecotoxicology
Lumbricina species are found in a large range of biota, from costal marine environments (i.e. Pontodrilus litoralis) to freshwaters (i.e. members of the Almidae family) and soils. However, most species are terrestrial, some of them living in mud or partially in freshwater. Haplotaxina species are mainly subservient to freshwater biota, including sediments.
