What is bryozoan.

Fossilized skeleton of Archimedes Bryozoan. Archimedes is a genus of fenestrate bryozoans with a calcified skeleton of a delicate spiral-shaped mesh that was thickened near the axis into a massive corkscrew-shaped central structure. The most common remains are fragments of the mesh that are detached from the central structure, and these may not ...

Bryozoan colonies have a variey of forms. Encrusting bryozoans form flat sheets that spread out over rocks, shells, and other substrates. Forms that grow upwards into the water column may be massive (solid), foliaceous (sheetlike, with zooids on both sides), dendroid (branchlike or treelike), or fenestrate (many branches joining and rejoining to form a netlike or "windowed" shape).

Bryozoan research has been continuously conducted in New Zealand since 1841 (Gordon et al., 2009) and a governmental agency, the National Institute of Water and Atmospheric Research (NIWA), is both the data manager and custodian for fisheries and invertebrate research data, hence assuring knowledge curation. All of this means that a cheilostome ...Bryozoan growth habits, or colony forms, are phylogenetically constrained in many groups and phenotypically plastic in others.

The three are sometimes referred to as the Lophophorata.Bryozoans are a classic "wild card" taxa, jumping around in otherwise stable phylogenies. They seem to be closer to Trochozoa than to Ecdysozoa or Deuterostomia in most molecular analyses. Alas, the bryozoan genome is as derived as its morphology, making it a difficult subject for molecular methods.Mar 8, 2023 · Sid Perkins. March 8, 2023 at 11:00 am.

Bryozoans have also evolved integrated colony-wide patterns that increase and channel feeding currents. In erect colonies, the orientation of expanded lophophores is controlled by the skeletal structure of the colony. Adjacent lophophores are oriented away from each other and toward interbranch spaces, creating a strong unidirectional current ...
