Bryozoan colonies
The Western Port bryozoan reefs are unique and globally significant because they: 1) occur in shallow water (typically 5-10 metres), 2) are dominated by delicate fenestrate colonies of T. moniliferum and T. munitum, 3) have two distinct morphologies (linear and patch-like), 4) form continuous rows of reef interspersed with fine sediment, and 5 ...Bryozoan fossils can be found in Kentucky's Ordovician, Silurian, Devonian, Mississippian, and Pennsylvanian rocks. Fenestrate bryozoa colonies, like the three diffenent types shown above, are lace-like in construction. The individual bryozoan animals lived in microscopic tubes or pores on the lace branches.Existing bryozoan colonial growth form classifications do not, however, fully exploit the ecological information present in colony form. A new scheme is proposed here (Analytical Bryozoan Growth Habit Classification), which provides a list of colony-level morphological characteristics for bryozoan growth habits. This differs from previous ...

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.

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.Thus, bryozoans typically form sessile colonies that live in marine and freshwater environments, and consist of individual zooids that are about 0.5 mm (0.02 in.) long. 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.
