What is a bryozoan
Bryozoans feed on small particulate material and would probably do well in some aquaria, particularly those with a good sand bed which produces a lot of bacterial particulates. They may also feed on the smaller varieties of phytoplankton such as small Nannochloropsis species.Bugulina flabellata is a colonial bryozoan forming small clumps up to 5 cm (2 in) high with a characteristic cone or fan-shape. The fronds have up to eight dichotomous branches with square tips. Each zooid bears two or three short spines. Colonies are dark buff when living and greyish when dried up. [2]

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).loensis is a bryozoan.

Bryozoa Bryozoans are colonial animals, meaning that many single zooids are stitched together to make one larger colony, akin to how corals grow. The zooids are soft bodied organisms with tentacles that live inside a cell that is part of the colony’s exoskeleton. The way these cells are arranged depends on the morphotype of the species. MorphotypesIf you have bryozoans in your pond, it is an indicator that you have a healthy ecosystem. Bryozoan feeding habits mean they filter the water as they feed, like oysters in saltwater, helping to consume algae and remove suspended sediments. Due to the flow of water and available food items around the colony, other small animals tend to congregate ...We use bryozoan (phylactolaemate, ctenostome, and cyclostome) and bilaterian out-groups and 18 fossil calibration points and present a time-calibrated bryozoan tree, asking how much of the early lineage leading to extant cheilostomes is now “invisible” (i.e., not detected) in the fossil record and when Bryozoa might have originated.…
