They bud in a single plane. In one specimen the wall microstructure is well preserved and it is composed of evenly spaced, linear fibers, running parallel to the axis of the stems, and connected by transverse bars. We discuss possible biological affinities of these organisms; we consider algal, poriferan, hydrozoan and bryozoan affinities.Hydrozoans (Obelia plana), sea squirts (Ciona intestinalis, Styela clava, Chelysoma siboya), bryozoans (Alcyonidium polyoum), and skeleton shrimp (Caprella acanthogaster, Caprella equiliba, Caprella kroyeri) attach on the nets and on ear-suspended scallops (Maru and Kosaka, 2005).

Bryozoan colonies have a superficial similarity with corals, but the anatomy of the bryozoan animal is much more complex. The entire complex is called a 'colony'; the individual functional units can be called ' zooids ', although 'polyp' is used for coral individuals, and 'theca' in the case of graptolites. Apr 23, 2021 · Finally, bryozoans are hermaphrodites, that is, they have female and male reproductive structures. They reproduce in a sexual and asexual way, with internal fertilization and indirect development. Morphology - External anatomy.
