Colony of bryozoan.

The preservation of these fenestellid bryozoan colonies is exceptionally fine and the colony illustrated in Fig. 1 is particularly intact. The largest fenestellid colonies reported are those from the Mississippian of North America that reached a maximum of 620 mm wide by 44 mm high in the case of Hemitrypa perstriata Ulrich (1890) (Snyder 1991).Bryozoans are tiny animals, no larger than 4 millimeters (5/32 of an inch) wide.

Bugula 'neritina' are colonial bryozoan whose individuals, called zooids, all work together to make the colony function as a single organism. Some zooids are responsible to collecting food while others are tasked with defense or reproduction.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.The bryozoan fossilization process often involves fragmentation (Key et al. 2016), so finding complete colonies may be a challenge. If the zooecial cavities are filled with carbonate cements and ...

Furthermore, some bryozoans have been shown to develop different and often-unusual colony morphology when kept in highly controlled laboratory conditions and fed microalgal monocultures . 23.

Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) [6] are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres ( 1⁄64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding.

Bryozoans are tiny, structurally complex organisms that live in colonies made up of modular, skeletonized living chambers called zooids. These microscopic homes allow their inhabitants to pop out to feed on plankton and then retreat if danger threatens. Within a single colony, multiple types of zooids may occur.

Bryozoans are members of the phylum Ectoprocta.The exoskeleton may be organic (chitin, polysaccharide or protein) or made of the mineral calcium carbonate. What type of zooid grows where in a colony is determined by chemical signals from the colony as a whole or sometimes in response to the scent of predators or rival colonies.

A freshwater bryozoan colony (Pectinatella magnifica) grows in a lake in Massachusetts. The colony is made up of thousands of tiny polyps that glean plankton out of the water column. "Magnificent Bryozoan" also knows as Sea Mats; Moss Animals; Lace Corals. Researchers in Virginia have identified an "alien pod" discovered in a local freshwater lake as a very large colony of freshwater bryozoans -- aka "moss animals."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).
