Streblospio benedicti
Taxonomic Group: Annelids-Polychaetes


Streblospio benedicti is a small tube-dwelling, highly productive, opportunistic polychaete commonly known as the bar-gilled mud worm. It is native to the Western Atlantic, from the Gulf of St. Lawrence to Venezuela. It has been introduced to Hawaii, the West Coast of North America (Mexico to British Columbia), and Europe (Poland to Spain). It is found in mudflats and soft-sediments in estuaries and coastal waters and can tolerate a wide range of temperatures and salinities. It can attain very high abundances in introduced locations and is probably a significant grazer of phytoplankton in these areas, but further impacts have not been investigated.
