Bryozoans are predominantly marine, epifaunal, sessile suspension feeders. They have a modular, colonial organization, each colony being composed of genetically uniform zooids that may be differentiated morphologically and functionally into autozooids (feeding zooids) and various types of heterozooids.Bryozoans are colony-forming organisms comprised of individual animals called zooids. For any given plate-shaped colony encrusting the surface of an ocean bed or sliver of seaweed, there can be up to thousands of individual zooids, all cooperatively fused together into a chimeric body scouring the currents for food.

And while zooids are small individuals on their own, colonies can be quite complex. Zooids within a single colony can come in different functions and morphologies – a bit like the organs in our bodies. This is known as zooid polymorphism and is associated with the division of labour within the colony.The “breadbasket colonies” were the North American colonies that produced more food than the other colonies in the country. These colonies were comprised of small farms that grew wheat, apples, peaches and other foods.Once referred to as ‘Ectoprocts’, bryozoans or moss animals are exclusively colonial animals formed of tens of thousands of modules called zooids. These colonies can encrust rocks, algae or ...

Apr 1, 2022 · The Bryozoa (moss animals) is a diverse phylum of colonial aquatic invertebrates found in almost all freshwater and marine environments. The phylum comprises ~6000 living species [] which grow into a bewildering array of colony types, including soft (weedy or gelatinous) and hard (calcified) forms, which may be moss-, sponge-, or coral-like in overall appearance.

Asexual reproduction occurs by budding off new zooids as the colony grows, and is this the main way by which a colony expands in size. If a piece of a bryozoan colony breaks off, the piece can continue to grow and will form a new colony.Taken during a freshwater mussel survey on Powder Mill Pond in Peterborough, NH.

Bryozoan colonies can take many forms, but most Recent species are encrusting sheets (McKinney and Jackson, 1991). Whether the encrusting sheet has come to be the dominant bryozoan colony form because it is advantageous is unclear. Although the phylogeny of bryozoans is far from resolved, the encrusting sheet form is found across theIntracolony variation in colony morphology in reassembled fossil ramose stenolaemate bryozoans from the Upper Ordovician (Katian) of the Cincinnati Arch region, USA.
