Hediste diversicolor
Taxonomic Group: Annelids-Polychaetes


Hediste diversicolor is known as the Common Ragworm. It is native to the Northeast Atlantic from Northern Europe to Morocco and the Mediterranean, Black and Azov Seas. Introduced populations are known from the Northwest Atlantic including the Gulf of St. Lawrence, the Bay of Fundy, and the Gulf of Maine. It is commonly found in muddy sediments in intertidal and shallow subtidal estuarine habitats with low or highly variable salinity. We treat H. diversicolor as a single species, but cryptic species are likely present throughout its global range.
