bryozoer
Bryozoer, or bryozoans, are a phylum of small aquatic invertebrate animals. Most species form colonies composed of many individual units called zooids that live together in a shared exoskeleton. Each zooid functions as its own animal, primarily feeding and maintaining the colony. Bryozoans are filter feeders that extend a crown of ciliated tentacles known as a lophophore to capture suspended particles from the water.
Colonies vary in form, being encrusting, branching, or stalked, and they attach to substrates such as rocks,
Feeding is carried out by the lophophore, which creates water currents and captures microscopic plankton and
Ecologically, bryozoans contribute to habitat complexity and can form reef-like structures in some regions. They are
