Aspects of mast building and the fine structure of “amphipod silk” glands in Dyopedos bispinis (Amphipoda, Dulichiidae)
In the present study, we investigated the biology of Dyopedos bispinis , a mast-building amphipod that is abundant near the N. Pertsov White Sea Biological Station. To examine the peculiarities of mast building in Dyopedos bispinis , we studied the social structure of individuals inhabiting the mast...

In the present study, we investigated the biology of Dyopedos bispinis , a mast-building amphipod that is abundant near the N. Pertsov White Sea Biological Station. To examine the peculiarities of mast building in Dyopedos bispinis , we studied the social structure of individuals inhabiting the masts and identified the preferred substrata through underwater photography and direct observations, characterized the internal and external structures of the masts, and studied the ultrastructure of pereopodal silk glands using scanning and transmission electron microscopy (SEM and TEM, respectively). The most frequent substrata for mast building are other fouling organisms, including hydroids, bryozoans, ascidians and sponges. As in other corophiids, each Dyopedos bispinis mast represents the territory of one female and, occasionally, one male, but unique collective masts occupied by three or more (up to 23) adults were also observed. Masts comprise one or 2-4 central cylinders and a laminated cortex that contains detritus and amphipod silk layers. The pereopodal glandular complex of Dyopedos bispinis is composed of two distinct gland groups, proximal and distal, in each pereopod 3-4, and ducts in the glandular complex lead into a common chamber in the dactylus.
