The development of the oocytes of Nereis (Hediste) diversicolor and Nereis (Nereis) pelagica takes up to 18 months from their first appearance in the coelom to maturity, and in the natural conditions experienced by the population studied in north-east England the females are in their second year before the oocytes begin to appear.

Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Previous studies on the common ragworm Hediste diversicolor (Polychaeta: Nereididae) revealed a marked genetic fragmentation across its distribution and the occurrence of sibling taxa in the Baltic Sea. The legs, parapods, are positioned closer together than for instance the legs of Hediste diversicolor. Mol Ecol 18:1980–1994 The other way around, as Hediste (Nereis) diversicolor, is wrong however, because in this case Nereis is not, and never will be, a subgenus of Hediste.

[Hediste diversicolor] and [Corophium volutator] in littoral mud Sheltered estuarine shores of sandy mud, which may become firm and compacted if present in the upper shore where there is more time for drainage between high tides. Macroscopically it is similar to other nereid species occurring in Nordic waters, e.g. hediste diversicolor (diverse colours and distinctive red blood vessel down back) phyllodoce lamelligera (dark green with blue irridescence) eulalia viridis ... (common periwinkle) littorina mariae. Hediste diversicolor: commonly known as a ragworm, is a polychaete worm in the family Nereidae. The biotope is typically found on the mid and lower shores in the upper and mid estuary. Microscopically it has a distinct pattern of paragnaths (small chitinous spines on the eversible pharynx), and al… It lives in a burrow in the sand or mud of beaches and estuaries in intertidal zones in the north Atlantic. Nereis (Hediste) Malmgren, 1867 Wikispecies has an entry on: Hediste . Hediste (after the first full mention only the generic name is used for the common species) can feed in three ways (Scaps, 2002, Durou et al., 2007). The harbour ragworm, Nereis (Hediste) diversicolor is a common intertidal marine polychaete that lives in burrows from which it has to partially emerge in order to forage. Virgilio M, Fauvelot C, Costantinif F, Abbiati M, Backeljau T (2009) Phylogeography of the common ragworm Hediste diversicolor (Polychaeta: Nereididae) reveals cryptic diversity and multiple colonization events across its distribution. Journal of the Marine Biological Association of the United Kingdom, Vol. In doing so, it is exposed to a variety of predators. is to roll down a slope to escape from predators. It is native to the Northeast Atlantic from Northern Europe to Morocco and the Mediterranean, Black and Azov Seas. Hediste diversicolor is known as the Common Ragworm. ... Hediste diversicolor. Myohemerythrin is an oxygen-binding protein found in the retractor muscles of certain worms. Thus Nereis (Hediste) diversicolor is correct because Hediste can be a subgenus of Nereis. it has one pair of antennae, one pair of palps and 4 pairs of tentacles.

The common ragworm Hediste diversicolor plays a pivotal role in sedimentary littoral ecosystems of the North Atlantic as an abundant prey item and ecosystem engineer, but exhibits a restricted dispersal capacity that may limit connectivity at both evolutionary and ecological time scales.
