What is a bryozoan.
Bryozoan colony attached to a rock in the Baudette River Each fall the bryozoans begin to die off, but create overwintering "eggs" that will form new colonies the next year. When the colony is dying, gas produced by decomposition may cause it to float loose, sending gelatinous globs floating down the river.
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).Bryozoans: Moss animals. Bryozoans are small, mostly marine animals that form skeletons of a variety of shapes: tiny twigs, nets, domes, and mossy crusts. The zooecium (skeleton) houses highly structured colonies of zooids, or cuplike animals. Bryozoans, like brachiopods, contain a tentacle-bearing lophophore used in feeding and gas exchange.Quadrisemicoscinium is an extinct genus of fenestrate bryozoan, known from the Early Devonian period, of the family Semicosciniidae. It formed net-like colonies of relatively thick branches with two rows of autozooids per branch, supported by a vesicular skeleton. Species. Three species are recognized.Bryozoans occur in both still and running waters. Their presence indicates good water quality. Movement: Most bryozoans are sessile and immobile, but some colonies are able to slowly glide on the substrate. Size: Individual zooids are about 0.5 mm long. Life cycle: The life cycle includes both sexual and asexual reproduction.
Mississippian limestones in Illinois are generally pure carbonate with little shale or sand and often have caves systems in them. The fossil fauna is highlighted by abundant and diverse crinoids and brachiopods, plus corals, bryozoans, including Archimedes (corkscrew bryozoan), molluscs, sharks, and fish, but trilobites are rare.BRYOZOANS are colonial animals that live in both freshwater and seawater. A colony is composed of hundreds of very tiny individuals, each of which has a special organ that filters small food particles from the water. Bryozoan colonies are attached to the seafloor or to other organisms.
Argentinodictya is an extinct genus of bryozoans which existed in what is now Argentina during the Late Ordovician.It was described by Andrej Ernst and Marcelo Carrera in 2012, and the type and only species is Argentinodictya lenticulata.. References

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. MorphotypesBryozoan found in 2014 in Lake Isabella, Mason County (photo courtesy of Erica Marbet). Bryozoans usually grow around a submerged branch, plant stem, or part of your dock. They can be long and thin or shaped like a ball, depending on the surface to which they are attached. Bryozoans have tiny tentacles that filter food particles from the water.
