Earthworms - Winter Wildlife

Earthworms are not actually a type of scientific classification but instead is the common name used to describe the largest members of Oligochaeta which are found in the phylum Analidia. Currently there are 29 species of earthworms in the UK that are considered native. And they are typically split into 3 ecological groups Epigeic, Endogeic and Anecic although some people also consider compost worms to be an extra ecological group.
