Types of Fouling Organisms

Biofouling communities are broadly categorized as either microfouling or macrofouling. Microfoulers included e bacteria and diatoms that create slimy films. Macrofoulers are divided intro hard and soft foulers. Hard foulers included barnacles, mussels, and encrusting yozoans that produce calcareous shells.
