| While C. virginica has not become established in Elkhorn Slough, 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), Atlantic Oyster Drill (Urosalpinx cinerea), tube-dwelling amphipods (Ampelisca, Ampithoe, Monocorophium spp.) and tunicates (Botryllus schlosseri, Molgula manhattensis) (Carlton 1979; Wasson et al. 2001; de Rivera et al. 2005). | ||
