Colony of bryozoan
Bryozoans are microscopic aquatic invertebrates that live in colonies. The colonies of different species take different forms, building exoskeletons (outer protective structures) similar to those of corals. Most colonies are attached to a structure such as a rock or submerged branch. Freshwater bryozoans' exoskeletons are gelatinous (like jelly) or …However, bryozoans are not closely related to marine corals. These gelatinous masses feed and reproduce together and range in size depending on the stage of the developing bryophyte. Figure 1 shows a newly forming bryozoan on a branch, however, a single colony can grow up to the size of a basketball. Bryozoans form colonies, like coral, that consist of thousands of microscopic animals called “zooids” spread around the surface of a hard, jelly-like mass. Colonies start out small in the spring, but may grow to more than a foot in diameter. Bryozoan found in 2014 in Lake Isabella, Mason County (photo courtesy of Erica Marbet).

Bryozoan growth habits, or colony forms, are phylogenetically constrained in many groups and phenotypically plastic in others. The many relationships among environmental factors and the distributions of bryozoan species (i.e., their concomitant growth habits) allows for paleoenvironmental analyses based on the occurrence of …Bryozoans, or "moss animals," are aquatic organisms, living for the most part in colonies of interconnected individuals. A few to many millions of these individuals may form one colony. Some bryozoans encrust rocky surfaces, shells, or algae. Others, like the fossil bryozoans shown here, form lacy or fan-like colonies that in some regions may ... Zooids live together in attached colonies that can be encrusting, like the white lacework of Membranipora, or branching, like the tufted erect bryozoan (this type looks just like a seaweed, except it is pink to tan in color). The "crust" is formed by a protective limestone covering secreted by the colony.
Colonies of magnificent bryozoan can grow more than two feet across and form slimy translucent brown masses that are often found attached to floating sticks or an underwater substrate; in rare occasions bryozoan can be found free floating. Each zooid found within a colony has separate body parts, but share certain tissues and fluids with unify ... Bryozoan colonies grow by zooidal budding, with the distribution pattern of the budding loci underlying the diversity of colony forms. Budding is usually restricted to the zooids at the periphery of the colony, which form a "growing edge" or local terminal growth zones. Non-budding parts of the colony can be functionally subdivided, too.If you've ever seen a light brown, gelatinous blob in your lake, you may have been looking at a bryozoan. Bryozoans form colonies, like coral, that consist ...moss animal. Moss animal - Colonial, Filter-Feeders, Habitats: Colonies in extant bryozoans are not just aggregations of zooids but whole organisms having an integrated physiology and behavior that appear to be coordinated to some extent. The most ancient bryozoans are from the Lower Ordovician. Phylum Bryozoa is divided into three classes and ...Bryozoan definition, belonging or pertaining to the Bryozoa. See more.
Bryozoans are found in freshwater, brackish and marine ecosystems throughout the world, from all depths and latitudes. ( Brusca and Brusca, 2003; Ramel, 2012) Biogeographic Regions nearctic native palearctic native oriental nativeBryozoans 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. Morphotypes ….

In the freshwaters of Delaware, you are most likely to encounter the native Magnificent Bryozoan ( Pectinatella magnifica) . This colonial species forms jelly-like “green blobs” on underwater vegetation, branches and other structures. They may also form free floating round colonies.
