FIGURE 3. Juxtacribrilina annulata (Fabricius, 1780). Chupa Inlet, Kandalaksha Bay, White Sea; A–D, F, ZIRAS 33/50736; E, from study by Ostrovsky (1998). A. View of colony; ancestrula indicated by arrow. B. Non-ovicellate zooids in basal layer. C. Non-ovicellate and marginal ovicellate zooids in basal layer. D. Enlargement of ovicellate zooid in basal layer, showing details of ooecium. E. Detached colony fragment with two frontally positioned dwarf ovicellate zooids and a reduced marginal ovicellate zooid (right); arrowhead indicates cylindrical proximal 'cauda' of dwarf zooid apparently arising from distal pore chamber of basal zooid. F. Ancestrula (center) and periancestrular zooids. Scale bars: A, 1 mm; B, C, E, F, 250 µm; D, 100 µm.
