Marenzelleria neglecta
Taxonomic Group: Annelids-Polychaetes


Marenzelleria neglecta is a spionid polychaete, one of several species of red-gilled mudworms. It is native to the Northwest Atlantic, but its full range is somewhat uncertain, owing to its long confusion with the congeneric M. viridis. Introduced populations are known from California, the Baltic Sea, the Netherlands, Germany, and Sweden. It inhabits mudflats and shallow muddy bottoms, usually in areas of variable or low salinity. In some introduced locations, it reaches high densities and can dominate benthic communities, displace native infauna, and affect the characteristics of sediments.
