Biofilm refers to the community of organisms which grows on any hard surface in the water, including the plankton associated with these communities. In the Chesapeake Bay there are many places where biofilm communities flourish: oyster beds, piers, rocks, even trash! Check out these links for activities and information about the biofilm:
