There are thousands of species of earthworms in the world. Those that live in the soil can generally be grouped into three major behavioral classes: the litter-dwellers, shallow soil dwellers, and deep-burrowers. The litter- dwelling species live in the litter layer of a forest, for example, and are generally absent from agricultural fields. Typical agricultural fields may have one to five different shallow-dwelling species and perhaps one deep- burrowing species.
