Bryozoan colonies

Bryozoans are colonial benthic marine invertebrate calcifiers, important and especially abundant and diverse in southern hemisphere shelf environments. Large heavily calcified colonies can be up to 50 years old, but most longer-lived bryozoans are limited to 10–20 y. Many smaller species are annual. Radial extension in flat encrusting bryozoans is generally on the order of 1–5 mm/y. Erect ...

Colonies grow throughout the summer and reach their largest size in late ...Bryozoans are zoologically unrelated to reef corals, of course, but their hard, calcareous crustose, mounded, and branching colonies superficially resemble those of cnidarians. Whereas in the tropics, bryozoans are mostly dwarfed by stony corals, in cooler temperate waters they come into their own, and can form bio-herms and mini-reefs.Pectinatella magnifica, the magnificent bryozoan, is a member of the Bryozoa phylum, in the order Plumatellida.It is a colony of organisms that bind together; these colonies can sometimes be 60 centimeters (2 feet) in diameter. The individual organisms termed zooids feed using a lophophore in which cilia on the tentacles capture microscopic organic …The majority of non-cheilostome bryozoan colonies are made up of normal feeding zooids, often small tubes from which a retractable cluster of tentacles can extend to pull in food morsels. These animals find strength in numbers, combining to form intricate branching patterns or delicate lacing that give them their namesake of moss animals.As a consequence, the whole colony achieved a distally tapering morphology (Figs. (Figs.1a, 1 a, a,2a, 2 a, 4a, b, Extended Data Fig. 5a, b). The exhalant currents of filtered water would probably have been vented out from the sharp colony edges by analogy with living bryozoans with palmate branches 1.Membranipora membranacea is a very widely distributed species of marine bryozoan known from the Atlantic and Pacific Oceans, usually in temperate zone environments. This bryozoan is a colonial organism characterized by a thin, mat-like encrustation, white to gray in color. It may be known colloquially as the coffin box, sea-mat or lacy crust bryozoan …

While zooids are microscopic, bryozoan colonies range in size from one cm (0.39 in.) to over one meter (3.3 ft.) across. However, most colonies are under 10 cm (3.9 in.) across.Bryozoans take responsibility for many of the colony forms, which have evolved in different taxonomic groups and vary in sediment producing ability. The nine basic bryozoan colony-forms include: encrusting, dome-shaped, palmate, foliose, fenestrate, robust branching, delicate branching, articulated and free-living.tubular colonies with bean-shaped statoblasts that cannot float are in the family Fredericellidae. Branching weedy colonies with oval statoblasts that do float are in the Plumatellidae. Most “nuisance” bryozoans are from this latter family. Adults within the freshwater bryozoan families look very similar, soThese colonies are attached to objects in the water—branches, aquatic plants, dock supports. One form of bryozoan doesn't have the gel-like appearance, but looks like a branching growth on hard objects like boat hulls. Habitat: Bryozoans are a primitive, ancient group of creatures whose fossil remains are found in rocks from long ago.

Other potential sources of variation (distribution of colonies of bryozoan species) include: (1) positional (edge) effects within the apparatus and among microhabitats (effects presumed to be minimal, but unknown), (2) positional (edge) effects within microhabitats (effects apparently significant, and partially accounted for in this study), (3) …
