Description Two twin species can be found in the North Sea: Capitella capitata and Capitella minima. These two species are morphologically very hard to distinguish from each other, hence we speak of a Capitella complex. Capitella looks like earthworms because the exterior appendages (parapodia and gills) are very much reduced. The body is rather fragile and may contract and/or expand. The head is built rather simply and tapers conically. The colour of the living specimens is purple. [details]
Distribution Barring a single exception the distribution of Capitella capitata/minima is limited to the near-coastal zone. In the 1976-1986 period the complex was found in the entire near-coastal zone with a low frequency of occurrence. In the 1994-2001 period the complex of species had a higher relative
occurence, but its distribution was limited to the western near-coastal zone. Its maximum density
increased from 40 ind./m2 in the 1976-1986 period to 700 ind./m2 in the 1994-2001 period. [details]
Etymology Not stated. Blainville (1828) refers to an indistinct head and a 'Capitellum' is a neuter diminutive noun for a small head, whereas Blainville appears to intend a feminine by using Capitella. He never uses 'capitata' as the species name however, including the species names Capitella fabricii and the original name Lumbricus capitatus [details]
Grammatical gender apparently feminine as Blainville formulates the name as Capitella instead of the neuter Capitellum [details]
Habitat Capitella capitata/minima is found in all sediment types present on the Belgian part of the North Sea. Although this species occurs in very fine to coarse sediments, it tends to prefer fine-grained sediments with a median grain size of 50-250 µm. Capitella capitata/minima is almost completely absent in sediments without mud. The maximum relative occurrence (> 60%) is observed in sediments with a mud content of 10-20% whereas C. capitata/minima has a relative occurrence of 20 to 30% in sediments with higher mud contents. [details]
Nomenclature When Blainville named genus Capitella he named the species as Capitella fabricii, a new name for Lumbricus capitatus, the species he was basing his new genus on. The 'fabricii' name is a superfluous replacement name and a junior objective synonym of Lumbricus capitatus. Sometimes early taxonomists may have invented new species group names to avoid creating tautonymous names (names in which genus and species are the same or little different, but it is not known if Blainville attempted a new species name for this reason. He could have instead used a different genus name.Almost no subsequent author adopted the name Capitella fabricii (but it was used by Grube, 1850: 352), but it was sometimes included as a synonym of Capitella capitata (eg Van Beneden, 1857). New names must be introduced for a stated reason (such as junior homonymy of the original name). It would be anarchy if original species-group names could be replaced by a different species-group name in later publications [details]From regional or thematic species database
