“…Various Idotea species have repeatedly been found in large numbers associated with floating seaweeds in the NE Atlantic (Franke et al, 1999;Ingólfsson, 1995;Tully and Ó Céidigh, 1986;Vandendriessche et al, 2006). Clarkin et al (2012b) showed that these isopods continuously colonize floating seaweeds. In general, rafting assemblages on floating seaweeds can be highly dynamic as rafts frequently break up and re-assemble in drift rows, where castaways may switch among rafts (Hobday, 2000).…”
