The familiar Nightcrawler, (Lumbricus terrestris). Probably our most familiar annelid, these tireless soil tillers are immensely useful recyclers of waste and aerators of gardens. The handsome specimen above clearly displays the segmented body of the annelids. Polychaete worms like the Feather Duster of the Eudistylia family are marine dwellers.
Two Classes and thousands of individual species of Phylum Annelidia represent wildlife in the Northwest:
Class Polychaeta - Predominately marine worms with distinct head, eyes, and tentacles
Class Oligochaeta - Earthworms and freshwater annelids
Class Hirudinea - Leeches
Red Tube Worm, Serpula vermicularis. A beautifully colored polychaete worm that stand out in dramatic contrast to Giant Feather Duster, Eudistylia, beside it. Growing only to four inches in length they are seen from low tide line to three hundred feet deep.
