This assay was previously used as a histological stain in studies of DOPA-containing adhesive proteins in polychaetes (Wang and Stewart, 2012) and DOPA-hardened hydroid perisarc (Hwang et al., 2013).
Marine hydroid perisarc: a chitin- and melanin-reinforced composite with DOPA-iron(III) complexes.
Hydroid: stolonal, hydranth 1-6 mm high, with very short pedicel, perisarc
of main stem moderately thick, thinner at secondary branches and pedicels.
No annulations on the perisarc
were seen and no gonophores were observed.
Long pedicels, 3.4-4.6 gin in length, 50-68 [micron]m in diameter; pedicel base with 2, 3 or 4 annulations; perisarc
Podocysts are essentially polyp-derived tissues encysted in a protective layer of perisarc
, and are able to withstand extreme salinity changes and desiccation, sometimes for years (Dumont, 1994; Ikeda et al., 2011; Carrette et al., 2014).
Resettlement of Iceland scallop (Chlamys islandica) spat on dead hydroids: response to chemical cues from the protein-chitinous perisarc
and associated microbial film.
caspia is difficult to control because colonies are able to regress, forming menonts, which are small pieces of tissue within the perisarc
of either the hydrocauli or hydrorhiza.
The colonies of thecate hydroids are covered with a chitinous tubelike outer skeleton, the perisarc
. The perisarc
shows a species-specific pattern of annuli, curvatures, and smooth parts.
The surface of the pawn is smooth and the first beginnings of a perisarc
, an outer noncellular protective coating, are seen at the base.
These mature colonies degenerated rapidly, and colonies with only perisarcs
were observed in August or September (surface water temperature, 26-30 [degrees]C),
