Organism information awaits expert curation
Class: Gymnolaemata

Size (Zooecium): Length 350-500 µ; breadth 110-130 µ.

Zoarium whitish in hue. Internodes long with 4 to 6 zooecia. Long zooecium with narrow more or less cylindrical proximal regions. Opesia occupy less than half of the front. The external lateral side of the zooecium produced into a flank. Two external and one internal spines. Scutum, frontal and lateral avicularia wanting. Bifurcation of type 11 of Harmer (1923). The joints traverse the opesia of the outer zooecia. Radicles arise from the external aspect of the proximal region of the zooecia.

Hermaphroditic. Reproduction may be sexual and asexual; bryozoan colonies consist of replicated series of zooids, each budded asexually from a predecessor. The founding zooid metamorphoses from the sexually produced larva.

It is also subject to competition and overgrowth from sponges, algae, and tunicates.
