FIGURE 1 in Revision of the genus Setosella (Bryozoa: Cheilostomata) with description of new species from deep-waters and submarine caves of the Mediterranean Sea

FIGURE 1. Setosella vulnerata (Busk, 1860), Leuca, Holocene, colonies from sample AP1 (a, c, j, k, l), AP8 (g, h, i, m) and AP21 (b, d, e, f). a–e Colonies on mollusc shell fragments, except for (d) on a lithic clast. Note the variably shape of the ancestrula and the arrangement of periancestrular autozooids sometimes leaving exposed the substratum. f. Irregular colony with broken ancestrula on an echinoid plate. g. Autozooid and vibracula. h, i. Ovicellate autozooid with dimorfic orifice, and associated distal vibraculum, in frontal and oblique view. j. Ovicellate autozooid with intramural budding. k–m. Three ancestrulae showing the variability of the opesia and the long stolk of the distal vibraculum. Scale bars: a–f = 500 μm; g, j–l = 100 μm; h, i, m = 200 μm.
