The properties of mucus, which allow resistance to microbial colonisation, can be divided into physical and chemical processes. Physical processes include its gel properties, such as thickness, entrainment, sloughing and viscosity. Chemical processes include those conferred by enzymes and secondary metabolites. The antibacterial metabolite shown here, Eunicellol A, is secreted into the mucus of the Arctic soft coral Gersemia fruticosa
