Bryozoa anatomy.

bryozoan , Aquatic invertebrate of the phylum Bryozoa (“moss animals”), members (called zooids) of which form colonies. Each zooid is a complete and fully organized animal. Each zooid is a complete and fully organized animal. 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.•Bryozoans are colonial and display characteristic zoarium (colony) and zooid morphology/anatomy. •Bryozoans can't eliminate nitrogenous waste, instead storing it in their tissues. They then can "eliminate" their internal tissue and regenerate from their body walls.Recent sampling of seamount and ridge habitats in the New Zealand Exclusive Economic Zone has yielded new cyclostome bryozoan taxa. We describe here one new genus, a new name, Dartevellopora (to replace the generic homonym Dartevellia Borg, 1944) and ten new species, comprising Filicisparsa albobrunnea n. sp. (Oncousoeciidae), Discantenna tumba n. gen., n. sp.

Anatomy. The interior of the shell is lined with a mantle, a membranous duplication of the body wall, through which respiration may occur and which secretes the shells. The shell is closed and opened by adductor and diductor muscles respectively. The scars of these muscles may be seen on the inside of the valves.

1 Anatomy. Bryozoa is a phylum of usually sedentary colonial marine invertebrates. Colony morphologies are diverse, typically encrusting or branching, many of them calcified. In all species, the majority or totality of the colony is composed of (typically) box- or cylinder-shaped “autozooids,” which feed, providing nourishment for the colony.
