Figure 36. Interzooidal epibiont in two Rhynchozoon species. (a–d) Rhynchozoon maculosum, NSMT- Te 1187 (paratype): (a, b) calcified tubes (arrowheads) secreted by bryozoan around epibiont, with occasional openings (arrows); (c) enlargement of calcified tube (asterisk), with broken area showing tubular structure of epibiont (arrowhead) in cross section; (d) epibiont emerging from between vertical walls of two newly forming zooids (asterisk); annular structure of emergent epibiont (arrowhead) suggests it may be a hydroid; note that epibiont appears to have suppressed avicularium formation. (e, f) Rhynchozoon scimitar, NSMT-Te 1206 (paratype): calcified tubes (arrowheads) secreted by bryozoan around epibiont, with epibiont opening indicated by arrow; note that epibiont appears to have suppressed avicularium formation. Panels are scanning electron microscopic images of bleached (a, b, e, f) or dried but non-bleached (c, d) material. Scale bars: a, b, d–f = 300 µm; c = 50 µm.
