| While C. virginica has not become established in Humboldt Bay, Eastern Oyster introductions have been a probable/possible vector for many fouling organisms and predators including Cliona sp. (boring sponges) and other sponges, polychaetes (Streblospio benedicti), slippershells (Crepidula convexa, C. plana), Atlantic Oyster Drill (Urosalpinx cinerea), and tunicates (Botryllus schlosseri, Molgula manhattensis) (Carlton 1979; Boyd et al. 2002; Wonham and Carlton 2005). | ||
