Figure 5 in The first catenicellid (Bryozoa, Ascophora) from Mediterranean shallow waters: a hidden resident or a new immigrant?

Figure 5. Catenicella paradoxa sp. nov. The "articulated basal complex". (A) Basal portion of the paratype specimen (PMC B 17b 5 July 2006) in Figure 2(A) showing a proximally located bifurcating bizooidal segment. Scale bar 200 µm. (B) Close-up of the "articulated basal complex" showing the relationships with the thick underlying wrinkled chitinous tube. Scale bar 200 µm. (C) A further paratype (PMC B 17b 5 July 2006) with a proximally located unizooidal segment apparently directly emerging from the Flabellia petiolata thallus surface, but note the possible presence of a diagonal basal tube under the detrital and organic cover. Scale bar 200 µm. (D, E) Dorsal and frontal side of the basal portion of the holotype specimen (PMC B 17a 5 July 2006) in Figure 2(B). Note the proximally placed fertile bizooidal segment and short rhizooids emanating from the dorsal proximal surface of the first zooid and attaching to the Jania rubens with their branching ends. Scale bars 200 µm. (F) Close-up of (E) showing the "articulated basal complex", partly concealed by detrital matter. Scale bar 100 µm. (G) Close-up of (D) showing the "articulated basal complex" not adhering to the substratum. Scale bar 100 µm.
