Pectinatella magnifica
Taxonomic Group: Bryozoans


Pectinatella magnifica is a freshwater bryozoan which forms large, slimy and gelatinous colonies. Its native distribution spans Eastern North America from New Brunswick and Ontario to Louisiana and Texas. It is introduced in the Western US (Oregon and Washington), Europe (France, Germany and the Netherlands) and Asia (Japan and Korea). It inhabits lakes and rivers and has been found attached to rocks, wood, aquatic vegetation, sponges, freshwater mussels, and other bryozoans. Although freshwater bryozoans can clog fishing nets and foul power plant and municipal water systems, there are no reported impacts of P. magnifica from its introduced range.
