Bryozoa, also known as Ectoprocta, is a major invertebrate phylum, whose members, the bryozoans, are tiny, aquatic, and mostly sessile and colonial animals. Also known as moss animals or sea mats, the colonial species of bryozoans generally build collective stony skeletons of calcium carbonate that are superficially similar to coral .Bryozoa. : Life History and Ecology. Bryozoans can reproduce both sexually and asexually. 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.1 Anatomy. Bryozoa is a phylum of usually sedentary colonial marine invertebrates. Colony morphologies are diverse, typically encrusting or branching, many of them calcified. In all species, the majority or totality of the colony is composed of (typically) box- or cylinder-shaped “autozooids,” which feed, providing nourishment for the colony.The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Institution , Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in ...Zooids can take several forms, but the most common forms in each class are autozooids, which function in feeding the colony and excreting waste. Branching bryozoans may look similar to branching corals, but the zooids in bryozoa do not have septa or a columella as corallites do in corals. Figure 7.19 – Common bryozoan fossils.Anatomy.
