Cover: A settled barnacle cyprid larva (Balaniusamphitrite) imaged from beneath using confocal laser scanning microscopy (see Aldred et al., pp. 1969−1972). Barnacle cyprid adhesive is present as two brightly fluorescent green deposits. Staining was accomplished using fluoresceinamine (green), a protein-sensitive fluorophore that highlights the proteinaceous inner phase of the glue deposit. Bacteria accumulate on and around the outer non-proteinaceous phase and are stained with Hoechst nuclear stain, appearing blue. The two-phase cyprid adhesive was previously believed to be a homogeneous mixture of components. Photo credit: Neeraj V. Gohad.
