Figure 5. Pentapora fascialis (Pallas, 1766), scanning electron micrographs of uncoated recent specimens imaged using back-scattered electrons. A, B, Tino Island, Italy, NHM 2007.9.14.14. A, group of autozooids, some with ovicells. B, autozooidal orifice and giant suboral avicularium. C, D, Oran, Algeria, NHM 1963.9.4.8. C, edge of branch showing autozooids (most with normal suboral avicularia) and marginal kenozooids. D, orifice and normal suboral avicularium. E, F, reputedly from Port Western, South Australia, NHM 34.2.20.15. E, inferred predator boreholes (arrowed) in frontal shields. F, giant suboral avicularia. Scale bars: A = 280 Mm; B = 100 Mm; C = 470 Mm; D = 60 Mm; E = 300 Mm; F = 100 Mm.
