FIGURE 4. Hornera currieae n in Hornera currieae n. sp. (Cyclostomatida: Horneridae): a new bathyal cyclostome bryozoan with reproductively induced skeletal plasticity

FIGURE 4. Hornera currieae n. sp. colony and branch morphology. A. Abfrontal view of fan-like colony bearing five gonozooids (TAN0104 stn 153). B. Proximal portion of large colony, showing basal disc attached to a scleractinan coral fragment; note rounded, immured basal branch stumps in Figs A–C (TAN0104 stn 153). C. frontal view of colony with large attachment disc and main stem stained brown, as is common in this species (holotype, NIWA 8449). D. Frontal view of distal branches showing hyaline skeleton and long lateral peristomes emerging at high angles from branch axis (TAN0104 stn 153). E. Developing branch tip showing budding of 2 x 2 frontal/lateral autozooid arrangement, frontal view (NIWA 8449). F. SEM of distal branch showing ongoing secondary calcification leading to tapered form (NIWA 8449). G. Abfrontal surface of developing branch tip, with transition from pustulose to smooth walls with secondary thickening (NIWA 8449). Scale bars: A, C, 5 mm; B, 3 mm; D, 2 mm; E–G, 500 µm.
