General Biology Additional Information	Ceramium virgatum colonizes rock and algal habitats from the midshore in rockpools to the open shore near to low water level and in the shallow subtidal (see Maggs & Hommersand, 1993). It also grows attached to the leaves of Zostera marina (see, for instance, Whelan & Cullinane, 1985). It occurs on bedrock through to pebbles. Dickinson (1963) notes that the species is either perennial or pseudoperennial. Settlement onto new surfaces can be rapid. For instance, panels were colonized within a month of being placed in Langstone Harbour (Brown et al., 2001)
