Figure 18 in Rocky-intertidal cheilostome bryozoans from the vicinity of the Sesoko Biological Station, west-central Okinawa, Japan

Figure 18. Pleurocodonellina microperforata Tilbrook: (a) NSMT-Te 1108, marginal autozooids showing one or two distal oral spine scars; (b) NSMT-Te 1108, ovicelled autozooids; (c) NSMT-Te 1112, ovicelled autozooids, with blunt suboral avicularia and larger pseudopores in ooecia; (d) NSMT-Te 1108, primary orifice, with sides of oral sinus nearly perpendicular; (e) NSMT-Te 1110, enlargement of orifice showing condylar denticulation; (f) NSMT-Te 1114, marginal autozooids, showing distribution of uniporous septula in vertical walls. All panels are scanning electron microscopic images of bleached specimens. Scale bars: a–c, f = 300 µm; d = 100 µm; e = 30 µm.
