Figure 3 in Taxonomy of the fouling cheilostome bryozoans Schizoporella unicornis (Johnston) and Schizoporella errata (Waters)

Figure 3. (A–F) Lectotype of Schizoporella errata (MM H1186.3113). (A) Growing edge of colony in primogenial unilamellar mode. (B) Portion of colony showing development of frontally budded zooids in intial phase of multilamellar growth. (C) Various stages of the development of the frontal shield of frontally budded autozooids. (D) Frontal shield of zooids in early astogeny with wide areolae and polygonal shaped border surrounding pseudopores. (E) Primary orifice and adventitious avicularia with operculum intact. The sinus is a wide U-shape with the proximal border of the orifice directed distally from the sinus. The avicularium bears an acutely pointed mandible with a hooked tip. (F) Primary orifice with operculum absent. Condyles small with acute tips. Scale bars: 1 mm (A, B); 500 µm (C); 250 µm (D); 50 µm (E, F).
