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.Closely packed zooids in encrusting bryozoan colonies pump water from ambient pressure above the colony to the higher base pressure prevailing under the lophophore canopy.Discover the beauty and history of Dutch Colonial architecture.

Colonies of Bryozoans are started by a single individual, which after its larval existence settles onto a substrate and after a little growth begins to reproduce asexually (by budding).

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.

This makes it possible to infer seasonal variation in temperatures experienced by the bryozoan colonies by measuring within-colony variations in zooid size (O’Dea and Okamura 2000).
