The family comprises marine annelids distributed in diverse benthic habitats across Oceania, Europe, South America, North America, Asia and Africa. [1] The Eunicid anatomy typically consists of a pair of appendages near the mouth ( mandibles ) and complex sets of muscular structures on the head ( maxillae ) in an eversible pharynx . [ 2 ]

This list of prehistoric annelids is an attempt to create a comprehensive listing of all genera that have ever been included in Annelida which have been found preserved as fossils. This list excludes purely vernacular terms.
Pleistoannelida is a group of annelid worms that comprises the vast majority of the diversity in phylum Annelida.Discovered through phylogenetic analyses, it is the largest clade of annelids, comprised by the last common ancestor of the highly diverse sister groups Errantia and Sedentaria (Clitellata and related polychaetes) and all the descendants of that ancestor.
The annelids, collectively called Annelida, are a large phylum of animals, comprising the segmented worms, with about 15 000 modern species including the well-known earthworms and leeches The main article for this category is Annelid .
Clitellate annelids are segmented worms characterised by the clitellum or girdle which is located near the head end of mature individuals. The mouth is on the ventral surface and is overhung by the prostomium (proboscis). The brain is not located in the head but in one of the body segments.
